Patent number: 10022220Abstract: Methods of implanting prosthetic heart valves for minimally invasive valve replacement are disclosed. In one preferred embodiment, a compressible and expandable prosthetic heart valve includes a support stent comprising an expandable tubular base and three upstanding commissure posts. The three commissure posts are spaced at 120 degree intervals. The prosthetic heart valve further includes a tubular flexible member which is secured to the support stent. The tubular flexible member preferably includes a prosthetic section and a fabric section. The prosthetic section is connected to the three commissure posts and defines three leaflets and three commissure portions. The commissure portions are secured along the commissure posts. The tubular base of the support stent may be self-expandable or balloon-expandable. The fabric section of the tubular flexible member surrounds the tubular base of the support stent for contacting an annulus of the native heart valve.Type: GrantFiled: April 3, 2014Date of Patent: July 17, 2018Assignee: Edwards Lifesciences CorporationInventor: Stefan Schreck

Publication number: 20180193131Abstract: Some embodiments are directed to a stent graft comprising a first stent graft having a first and a second stent and a first and a second inner graft supported by the first stent, and an outer graft. The second inner graft can be spaced apart from the first inner graft so that a portion of the first stent is not covered by either the first inner graft or the second inner graft. A first and second portion of the outer graft can be attached to the first stent, the outer graft being unsupported by the stent between the first and second portions so as to form a fillable space between the outer graft, the first inner graft, and the second inner graft. Some embodiments further comprise a second stent graft deployable within the inside of the first stent graft to sealingly cover the uncovered portion of the first stent.Type: ApplicationFiled: March 5, 2018Publication date: July 12, 2018Inventors: Stefan Schreck, Daniel Hawkins

Patent number: 9961062Abstract: In various example embodiments, an authentication server provides a secure communication pathway between a client device and a service provider. The authentication server has been previously authenticated with the service provider and establishes a tunnel for receiving requested information from the service provider. The tunnel is implemented according to Representational State Transfer (“REST”) principles, so the client device can send one or more REST requests to the authentication server, which then redirects such requests to the service provider via the established tunnel. In addition, the client device may be previously authenticated with the authentication server such that the client device does not need to explicitly authenticate to the service provider each time information is requested.Type: GrantFiled: July 21, 2015Date of Patent: May 1, 2018Assignee: SAP SEInventors: Marko Degenkolb, Sascha Kiefer, Christian Schmitz, Stefan Schreck

Publication number: 20170304098Abstract: A modular catheter system including a sheath projecting distally from a delivery catheter having a main body module. An inner core module carrying a stent thereon, the inner core being axially movable through the main body of the delivery catheter and the delivery catheter sheath, a handle member supported by the main body of the delivery catheter, the handle member being selectively axially engageable with the inner core such that the handle member and the inner core move together in an axial direction when the handle member is engaged with the inner core; and an adjustment member supported by the main body, the adjustment member being configured such that rotation of the adjustment member causes the adjustment member to move axially along the main body by either axially sliding the handle member relative to the main body or by rotating the adjustment member.Type: ApplicationFiled: June 23, 2017Publication date: October 26, 2017Inventors: Stefan Schreck, Elbert Tzeng, Todd Abraham, Jonathan Phan, Joshua Benjamin, Jacqueline Macias, Kevin Chu, Bill Gould

Publication number: 20170296791Abstract: Some embodiments are directed to a catheter system comprising an introducer having a main body, an introducer sheath projecting from the main body, and a first seal supported within the introducer and a catheter having a main body, an outer sheath projecting from the main body, a second seal supported within the catheter, and an inner core configured to be advanced axially through the main body, the second seal, and the outer sheath. The introducer can be configured to be selectively engageable with the catheter so that the catheter can be selectively and removably linked with the introducer in the axial direction. The catheter system can also be configured such that, when the introducer and the catheter are linked, the catheter can be rotatable relative to the introducer. The introducer can be configured to radially restrain an endoluminal prosthesis.Type: ApplicationFiled: June 30, 2017Publication date: October 19, 2017Inventors: Joshua Benjamin, Stefan Schreck

Publication number: 20170007263Abstract: Methods for treatment of aneurysms using a sequential manifold console to deploy multiple filling structures are provided herein. In one aspect, aneurysms are treated by simultaneously filling two double-walled filling structure using a sequential manifold console to guide a user in the steps to be followed in the procedure and to reliably achieve a consistent and durable aneurysmal treatment using a curable medium. The structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Pairs of filling structures delivered to the aneurysm from different access openings of a patient can be simultaneously prepared and pressurized from a single treatment console when treating abdominal aortic aneurysms using the described systems and methods.Type: ApplicationFiled: July 8, 2016Publication date: January 12, 2017Applicant: ENDOLOGIX, INC.Inventors: Stefan Schreck, Jason Fox

Publication number: 20160354206Abstract: An annuloplasty ring having a three-dimensional discontinuous form generally arranged about an axis with two free ends that are axially offset. The ring is particularly suited for repair of the tricuspid valve, and more closely conforms to the annulus shape. The ring is more flexible in bending about radially extending axes than about the central axis. The ring may have an inner structural support covered by a pliable sleeve and/or a fabric tube. The structural support may have a varying cross-section, such as a C-shaped cross-section in a mid-section between two free ends and a rectangular cross-section at the free ends. A deliver template having a mounting ring with about the same shape as the ring facilitates implant, and may be releasably attached to a delivery handle. The deliver template may include a plurality of cutting guides for releasably attaching the annuloplasty ring thereto while presenting maximum outer surface area of the ring.Type: ApplicationFiled: August 15, 2016Publication date: December 8, 2016Inventors: Patrick M.

Patent number: 9289536Abstract: A method for forming a material in an in situ medical device by initiating polymerization of water soluble polymer precursors in an aqueous solution during or after transport of the polymerizable solution from its storage container to a space inside the in situ medical device is described. The stored aqueous solution with water soluble precursors lacks a free radical initiator which, in a powder form, is introduced into the aqueous solution during or after its transport into the space inside the in situ medical device. This storage and delivery system provides greater stability to the stored aqueous solution, allowing it to be stored at ambient temperature and providing extended shelf life over the solutions used in existing in situ polymerization systems. The flexibility to store and deliver/transport only one aqueous solution, instead of requiring the use of two different solutions, is also a benefit.Type: GrantFiled: March 7, 2014Date of Patent: March 22, 2016Assignee: Endologix, Inc.Inventors: Charles Bankert, Paolo Mendoza, Stefan Schreck
