Ascension Technology teams with CIVCO on new medical procedure

first_imgCIVCO Medical Solutions and Ascension Technology Corporation, based in Burlington, have announced a new biopsy needle localization and guidance system for minimally invasive medical procedures.When integrated with 3D ultrasound visualization tools it enables accurate, percutaneous targeting to lesions without radiation or open surgery.  The companies will show live demonstrations of the system at SIR 2009, San Diego, CA, March 7 – 12, 2009.Ascension developed the world’s smallest six degrees-of-freedom (DOF) sensor, 0.9mm in diameter, for the application.  Key advantages include: inconspicuous guidance of surgical instruments, metallic immunity, and fast, simultaneous tracking of multiple sensors. CIVCO has designed a proprietary tracking needle with a protective reusable housing for the six degrees-of-freedom (6DOF) sensor.  Combined with the Ascension sensor technology, the needle allows simultaneous tracking of the distal tip of the needle and the ultrasound scan planes allowing clinicians to visualize the necessary patient anatomy as well as the position of the needle tip in real-time.Ultrasound imaging alone cannot always guarantee the tip of a needle or the electrodes of an ablation probe will hit the center of a three-dimensional lesion – especially a small one.  The new approach takes the estimation and inconsistencies out of ultrasound-assisted biopsy and RF ablation by instantly tracking both the 3D location of the ultrasound transducer and the tip of the needle.  If pre-operative imaging is indicated for selecting the best interventional path or for comparing the results of different imaging modalities, the sensor aligns the real-time ultrasound image with the pre-operative image in a process called image fusion.Procedurally, the sensor’s real-time spatial data is graphically overlaid on video images of the B-scan plane.  The clinician can then monitor the real-time trajectory of the needle through delicate anatomy of the geometric center of an internal target, such as a tumor, cyst or polyp.  This process clearly visualizes the location of the needle – either “in” or “out” of plane – for either a longitudinal or transverse approach.  Even before the skin is punctured, the system registers the biopsy needle to the center of the target, predicting the path of the needle while avoiding other anatomical structures.  As the needle advances towards the target, the fused images provide real-time feedback as the path to be taken.  Once optimally positioned, the needle can be rotated to a perpendicular plane to provide three-dimensional verification that the tip is on target.  Targets can also be marked and mapped for follow-up. Measurements are unaffected when tracking in close proximity to intravascular ultrasound arrays, composite beds, low frequency noise sources, and common hospital metals, such as 300-series stainless steels, titanium, and aluminum.  When used with Ascension’s flat magnetic field generator, the system can be used on gurneys, hospital beds, and procedural tables without distortion of measurements by the presence of ferromagnetic metals.At SIR, CIVCO will demonstrate the device in Booth #108. Ascension will demonstrate in Booth #1442.  About CIVCOWith over 25 years of experience, CIVCO Medical Solutions is recognized as an industry leader in enabling technology for improved treatment outcomes.  Its products continue to be the benchmarks for quality and design in diagnostic ultrasound imaging, patient positioning and radiation oncology.  CIVCO’s commitment to enhancing patient care is strengthened by the relationships built with clinicians and original equipment manufacturers (OEMs) around the globe.  The company’s ongoing collaborative research and development efforts seek to simplify procedures and improve the quality of care for patients.  Corporate information and product information is available at is external)About AscensionAscension Technology Corporation is a world leader in magnetic 3D localization and guidance for medical applications.  Its third generation magnetic sensors represent the key enabling technology for image-guided procedures.  More information about Ascension trackers along with streaming video is available at is external)Biomedical reference and procedures described herein are examples of what can be accomplished with 3D tracking and imaging technology when used in compliance with pertinent FDA/CE/IRB directives.Procedural or Applications Patents Pending.Source: Ascension Technology.

Coach Doc Rivers enjoying Clippers’ defensive trend

first_imgClippers coach Doc Rivers was still raving about the defensive effort his team gave in its 112-91 victory over Denver on Saturday.But even more impressive to Rivers was it represented the fourth consecutive game the Clippers held an opponent to fewer than 100 points in a game.“I do like the trend,” Rivers said. “I think we’ve been trending that way for a while defensively and it’s nice. My belief is you can play defense every night, offense you can try to play every night but it might not work out for you. You can miss open shots and just have a bad night, but your defense should always be there. At least the effort.”It’s not just at one end of the court, either. The Clippers limited Denver to six fast-break points in addition to the Nuggets’ 35.7 percent shooting from the field. Recently, the talk of the Clippers’ defense has started with the almost fanatical way Jordan has embraced his role as the defensive captain.“It starts with our bigs. DJ and Blake (Griffin) have been amazing,” Rivers said. “DJ’s leadership defensively – It’s funny, he’s mad the most on defense now, which I love because he takes it so personal when anybody scores.“Earlier in the year I thought he took it personally when his guy scored. Now he’s taking it personal if a guy’s making a 3 on the opposite side of the floor.“That’s what you need to take scoring personal and I think our guys are starting to do that.”Chirp chirpRivers was asked if the Clippers were the type of the team that could get under the skin of the other team on the court.“I noticed that last year. We probably talk,” Rivers said, “I don’t know what the hell’s going on out there. I really don’t.“We’ve just got to keep playing. I hate when we get distracted by it. I think we’re getting better but that’s an area we still have to improve in. We’re getting better also at leaving the officials alone and playing. We still have to get better there.”As if to prove that point, less than two minutes into the second quarter Jordan picked up his third foul. And a technical foul.Less than five minutes later, Rivers picked up a technical of his own. “We’ve had the effort in my opinion all year. We just weren’t in the right places all year and now we’re starting to get to the right places, the right spaces, and our talk defensively has been phenomenal. Our weak side defense has been improving. “Last night was one of our better nights because Denver runs. Against them that’s saying a lot . We’re starting to obey our rules, which is nice.”Opponents are noticing too. It didn’t surprise Minnesota coach Rick Adelman.“They certainly had the tools to do that,” Adelman said. “They had the size with (DeAndre) Jordan, and they’re active, and Chris (Paul) has always been one of the better point guards defensively too. It’s just something that as they play more under Doc, they’ll continue to get better defensively.”It’s personal nowcenter_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more

Clippers sign forward Johnathan Motley, guard Derrick Walton

first_imgThe Clippers also recently signed Amir Coffey to their other allotted two-way contract, which allows players to spend a maximum of 45 days with the NBA team while otherwise playing for the G League squad.Walton will join the team on an Exhibit 10 deal. The 6-1 former Michigan standout is the only Wolverine with 1,000 points, 500 rebounds and 400 assists. He also holds the program’s single-game assist record (16).Walton played for the Miami Heat on a two-way contract in 2017-18, when he appeared in 16 games and averaged 1.8 points,  and he has international experience, having played in Lithuania and Germany.This summer, he played in four games with the Clippers Summer League contingent, averaging 4.3 points, 1.8 assists and 1.8 rebounds in Las Vegas. The Clippers added a couple of promising players to the mix this week.No, not the pair they introduced in a celebratory news conference at Green Meadows Recreation Center on Wednesday, where hundreds of media members were on hand to hear introductory comments from new Clippers superstars Kawhi Leonard and Paul George.The Clippers also brought aboard 24-year-old point guard Derrick Walton Jr. on an Exhibit 10 contract – a one-year contract that pays a minimum salary but offers bonuses intended to compel a player to stick with the franchise’s G League program – and brought back 24-year-old power forward Johnathan Motley, again as a two-way player, an NBA source said.Clippers fans are familiar with Motley, who impressed last season as he split time between the Clippers and the organization’s G League affiliate in Ontario. With Agua Caliente, he averaged 24.5 points and 9.9 rebounds and shot 55.3 percent from the field in 27 games, production for which the 6-foot-10 prospect from Baylor was named to the All-G League second team. The honor was appreciated, though not unexpected, Motley said last season, after he and fellow two-way standout Angel Delgado were honored by the G League. “We’re supposed to get it,” Motley said. “We want to be NBA players … so those are awards we’re supposed to get.“We’re supposed to dominate at that level every night, and I think we did a good job of that this year, showing that we’re NBA players. We’re very thankful for the G League awards, but we have a higher goal in mind.”On the big stage with the L.A. Clippers, Motley – whom Dallas initially signed as a two-way player in 2017 before trading him to the Clippers last year – appeared in 22 games, 4.6 points and 2.3 rebounds and 7.1 minutes.“When we got him, I wasn’t too familiar with the overall personnel of the entire G League, but everybody told me, ‘This is a top center in the G League,’ ” Bryan Adams said before coaching a G League team last season. “And Mot had an amazing training camp for us with the big team, so the thing that I’ve been telling him is while I’m excited to have him here, the goal is to make him stay up there. He’s great, he’s supposed to be one of the more legit guys and I can see why.”Surmised Delgado, in respect to his buddy in the post: “He’s probably the best offensive big man I ever played with. He’s a bucket.”center_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more

Camper is `doing well’

first_img It didn’t matter, though. “This,” Lorraine Camper said, “is going to be the best New Year’s ever.” 160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set! “But they (doctors) say he’ll probably go back into his (general) room once it goes down a little, either (Saturday night) or (this) morning.” According to doctors “the (transplanted) kidney is doing well and producing gallons (of urine),” she said. More than 24 hours after receiving a kidney from Brenda Wells, Brian Camper was in “good spirits” while recovering in an intensive care unit room at Cedars-Sinai Medical Center in Los Angeles, his mother said early Saturday evening. “He’s not in any pain … he’s doing well,” Lorraine Camper said the day after her 34-year-old son, a resident of Lakewood and middle school teacher in Compton who was a basketball standout at Lakewood High and Long Beach State, underwent surgery for the transplant. Camper, who had been on dialysis for four years, was moved into the ICU room “when his blood pressure got a little high (Friday evening),” his mother said. center_img Camper, who is on a catheter, has been resting comfortably, watching television and seeing some visitors, including his mother and wife, Jennifer. Wells, who is from New Cumberland, Pa., and contacted Camper in August when she learned she was a possible match, was still in pain Saturday evening. “I’m a little rough around the edges right now,” she said, speaking on Lorraine Camper’s cellular phone. “But, otherwise, I’m feeling pretty good.” Lorraine and her daughter-in-law take turns visiting with Brian and Brenda. The celebratory toasts for New Year’s will have to come another time, perhaps when Camper and his family reunite with Wells. last_img read more
