Medtronic owes spine doc inventor $24m for patent infringement Medtronic must fork over nearly $24 million to the physician inventor behind a group of patents covering a technique for treating spine defects. Dr. Mark Barry sued Medtronic in February 2014 in the U.S. District Court for Eastern Texas, alleging infringement for 3 patents covering a “system and method for aligning vertebrae in the amelioration of aberrant spinal column deviation conditions.” Read more 4. FDA panel recommends approval TransMedics lung transplant device An FDA advisory panel yesterday recommended that the federal safety watchdog approve a device made by TransMedics to keep donated lungs perfused during transport to transplantation procedures. The FDA’s Gastroenterology &Urology Devices panel voted 11-2 that the OCS Lung system is safe; 8-5 that it’s effective; and 9-4 that its benefits outweigh the risks, an FDA spokeswoman told MassDevice.com via email. Read more 3.

This report presents 3 procedures with visceral “chimney stenting” in conjunction with an endovascular aneurysm sealing (EVAS) device, known as chEVAS, for treatment of type 1a endoleak. It includes the first published chEVAS in a patient with previous fenestrated endovascular aneurysm repair (FEVAR). Cases include an 80-year-old man 8 years after FEVAR for a juxtarenal abdominal aortic aneurysm (AAA); an 85-year-old woman 9 months after endovascular aneurysm repair (EVAR) for a ruptured infrarenal AAA; and an 84-year-old woman 3 months after EVAR for a symptomatic infrarenal AAA. Technical success was achieved...

Publication date: May 2018 Source:Journal of Vascular and Interventional Radiology, Volume 29, Issue 5 Author(s): Ramsey Al-Hakim, Libby Watch, Alex Powell An 83-year-old man with bilateral common iliac artery aneurysms (right, 3.0 cm; left, 2.7 cm), bilateral internal iliac artery aneurysms (right, 3.4 cm; left, 2.6 cm), and an abdominal aortic aneurysm (3.8 cm) was treated with an aortobi-iliac stent graft and bilateral iliac branch devices. The internal iliac components were extended into opposing posterior (left) and anterior (right) divisions of the internal iliac artery using stent grafts. Computed tomography angiog...

A 66-year-old man presented with an infected bilateral renal artery (RA) branch fenestrated endograft (Fig 1) placed 14 months earlier for a juxtarenal abdominal aortic aneurysm. Explantation of the endograft, axillobifemoral bypass, and right external iliac artery –to–right RA bypass graft (with cryopreserved superficial femoral artery; Fig 2) were performed. This involved proximal and distal transection and exclusion of the stent-implanted portion of the right RA. The patient’s tenuous condition and increased intraoperative risk precluded further disse ction to remove the transected right RA stent graft...

An 83-year-old man with bilateral common iliac artery aneurysms (right, 3.0 cm; left, 2.7 cm), bilateral internal iliac artery aneurysms (right, 3.4 cm; left, 2.6 cm), and an abdominal aortic aneurysm (3.8 cm) was treated with an aortobi-iliac stent graft and bilateral iliac branch devices. The internal iliac components were extended into opposing posterior (left) and anterior (right) divisions of the internal iliac artery using stent grafts. Computed tomography angiography demonstrated that all aneurysms decreased or were stable in size with patent stent grafts at 1 month.

This study sought to quantify EndoAnchor (Medtronic Vascular, Santa Rosa, Calif) penetration into the aortic wall in patients undergoing endovascular abdominal aortic aneurysm repair and to assess predictors of successful penetration and its relationship to postprocedural type IA endoleak.

Recognizing that some abdominal aortic aneurysm (AAA) endografts have a small offset between the radiopaque markers and the proximal fabric edge that may result in unintended partial renal artery coverage, the authors investigated the hemodynamic effect of this potentially adverse event. It is generally accepted that blood flow-induced low arterial wall shear forces are associated with development of atherosclerosis (wall shear force per unit wall area is wall shear stress, WSS) and that extremely high shear rates may produce thromboembolism with or without local turbulence.

Incisional hernia is a frequent late complication after open abdominal aortic aneurysm (AAA) repair. We aimed to determine whether prophylactic mesh reinforcement of the abdominal wall at open AAA repair via midline laparotomy reduces the rate of incisional hernia compared to standard sutured closure.
