Publication number: 20170128240Abstract: Devices and methods for treating aneurysms, such as abdominal aortic aneurysms (“AAA”) generally include one or more stent-graft devices. Some embodiments include self-expanding and/or balloon-expandable stent components and one or more graft components coupled with the stent components. Using various combinations of self-expanding stent members, balloon-expandable stent members, graft members, and/or anchoring members enhances the anchoring abilities of a stent-graft device to prevent leakage around it, and may further allow the device to be adjusted after placement at a site for treatment. Some embodiments further include a skirt graft member for further prevention of leakage and/or device slippage.Type: ApplicationFiled: July 6, 2016Publication date: May 11, 2017Inventors: Mark Deem, Hanson S.

Patent number: 8579915Abstract: The present invention provides an obstruction removing device and a method for making the obstruction removing device. The method includes two mandrels with an elongate element being wound around the first mandrel and then wrapped around the second mandrel. The mandrels are movable relative to one another so that the second mandrel may be moved closer to the first mandrel after winding the element around the first mandrel and before winding the element around the second mandrel.Type: GrantFiled: January 17, 2012Date of Patent: November 12, 2013Assignee: Concentric Medical, Inc.Inventors: Ron French, Scott Wilson, Neil Barman, Emily Vu, John Miller

Patent number: 8016871Abstract: Blood vessels and other body lumens are stented using multiple, discreet stent structures. Stent structures may be balloon expandable or self-expanding and are delivered by a delivery catheter which is repositioned to spaced-apart delivery sights. By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having both a pusher rod for advancing the stents relative to a sheath and a reciprocatable delivery catheter for implanting the stents.Type: GrantFiled: June 10, 2009Date of Patent: September 13, 2011Assignee: Xtent, Inc.Inventors: Sunmi Chew, Bernard Andreas, Hanson S.

Patent number: 8016870Abstract: Blood vessels and other body lumens are stented using multiple, discrete stent structures, or continuous coiled or mesh stent structures. Stent structures may be a balloon expandable or self-expanding and are delivered by a delivery catheter which is repositioned to spaced-apart delivery sites. By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having a deployment mechanism for deploying one or more stents of selectable length into the vessel.Type: GrantFiled: November 12, 2007Date of Patent: September 13, 2011Assignee: Xtent, Inc.Inventors: Sunmi Chew, Bernard Andreas, Hanson S.

Publication number: 20110178589Abstract: Blood vessels and other body lumens are expanded using an evertible braided prosthesis. The braided prosthesis is delivered to the blood vessel in a radially collapsed configuration. A leading edge of the braided prosthesis is then everted so that it expands as it is advanced through the blood vessel. Optionally, the prosthesis can be provided with a biologically active substance in order to inhibit hyperplasia or have other desired biological effects.Type: ApplicationFiled: April 1, 2011Publication date: July 21, 2011Applicant: XTENT, INC.Inventors: Bernard Andreas, Ron French, Mark E.

Patent number: 7314484Abstract: Methods and devices provide delivery of one or more therapeutic agents to a treatment site at or near an aneurysm, such as an abdominal aortic aneurysm (“AAA”). Methods typically include placing a device at or near the AAA and releasing one or more therapeutic agents from the device. This may also involve releasing multiple agents in sequential fashion. Examples of possible therapeutic agents include doxycycline, roxithromycin, tetracycline, tetracycline derivatives, and collagen promoting agents, such as propranolol. Devices used to deliver one or more therapeutic agents may include stents, grafts, stent grafts, balloons with perforations and/or needles, expandable wire baskets, drug-eluting capsules, or suitable combinations thereof. One embodiment includes a stent graft with a distally-extending skirt and an supra-renal anchor.Type: GrantFiled: July 1, 2003Date of Patent: January 1, 2008Assignee: The Foundry, Inc.Inventors: Mark Deem, Hanson S.

Publication number: 20070270936Abstract: Methods and apparatus for delivering prostheses to body lumens, such as stents and grafts to blood vessels, utilize a delivery device which carries one or more linearized elements. The linearized elements assume non-linear configurations, particularly helical configurations, when advanced and released from the delivery device. By selectively controlling the length and/or number of elements delivered from the delivery device, extended and disseminated disease within the body lumens may be effectively treated.Type: ApplicationFiled: August 8, 2007Publication date: November 22, 2007Applicant: Xtent, Inc.Inventors: Bernard Andreas, Ron French, Allan Will
