Patent number: 11395725Abstract: The present invention provides a package comprising an aortoiliac artery graft and a record of a measured pressurized diameter of the aortoiliac artery graft, which measurement has been determined ex vivo under a pressure. A method of processing an aortoiliac artery graft is also provided. The processing method comprises subjecting an aortoiliac artery to a pressure ex vivo, and determining a measured pressurized diameter of the aortoiliac artery under the pressure. A method of treating abdominal aortic aneurysm, infected aortoiliac endograft or a traumatically damaged abdominal aorta or an iliac artery in a patient is further provided. The treatment method comprises anastomosing a processed aortoiliac artery graft with an aorta of the patient on the proximal end and the iliac or femoral arteries on the distal end, wherein a measured pressurized diameter of the processed aortoiliac artery graft has been determined ex vivo under a pressure.Type: GrantFiled: September 19, 2018Date of Patent: July 26, 2022Assignee: LifeNet HealthInventors: Alyce Linthurst Jones, Jason B. Schulte, Eric Moore, Perry L. Lange, Rex Nagao

Patent number: 8337411Abstract: Described herein are devices, systems, kits and methods for measuring intra-abdominal pressure (IAP) from a patient catheterized with a urinary catheter system. Devices may include a bypass lumen configured to connect to a pressure transducer, a sampling port connector connected to the bypass lumen, a drain tube housing configured to at least partially enclose a portion of the drain tube of a urinary catheter system, and a clamp mechanism. The sampling port connector may be configured for removable attachment to the sampling port of the urinary catheter system to form a fluid connection between the urinary catheter system and the bypass lumen of the IAP device. The clamp mechanism may be configured to controllably occlude the lumen of the urinary catheter system drain tube.Type: GrantFiled: July 13, 2006Date of Patent: December 25, 2012Assignee: C. R. Bard, Inc.Inventors: Vasu Nishtala, Rex Nagao, Scott D. Ferguson, Robin J. Hanson, Anatoly Solunin, Alexander Shamray

Patent number: 5830191Abstract: A flexible endoscopic surgical port comprises a trocar tube or cannula made partially or entirely of flexible material which can be inserted into a body wall at an intercostal location to allow the insertion and manipulation of endoscopic surgical instruments within the thoracic cavity. The surgical port includes a hollow tubular body which is inserted through an intercostal opening in the body wall extending into the thoracic cavity with an annular flange at one end of the tubular body projecting radially outward and engaging the body wall adjacent to the opening. The flange is able to flex relative to the tubular body whereby the surgical instrument inserted in the tubular body can be manipulated over a wide range of motion inside the thoracic cavity. A retainer ring can be installed at the end of the tubular body opposite to the flange to secure the surgical port in the body wall. Improved obturators are provided for installation of the flexible surgical port.Type: GrantFiled: January 10, 1994Date of Patent: November 3, 1998Assignee: Ethicon, Inc.Inventors: Roger L. Hildwein, Robert C. Uschold, J. D. Staley, Jr., Paul Riestenberg, Laura Gallagher, Rex Nagao
