Apparatus And Methods For Deployment Of Multiple Custom-Length Prostheses (Iii)

View page
US Patent:
7320702, Jan 22, 2008
Filed:
Jun 8, 2005
Appl. No.:
11/148546
Inventors:
Dan Jeffrey Hammersmark - San Mateo CA, US
Stephen Kao - Sunnyvale CA, US
Craig Welk - Tracy CA, US
Pablo Acosta - Newark CA, US
Joseph Karatt - Millbrae CA, US
Assignee:
Xtent, Inc. - Menlo Park CA
International Classification:
A61F 2/06
US Classification:
623 111, 623 112
Abstract:
Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.

US Patent:
8083788, Dec 27, 2011
Filed:
Nov 28, 2006
Appl. No.:
11/563793
Inventors:
Pablo Acosta - Newark CA, US
Bernard Andreas - Redwood City CA, US
Stephen Kao - Sunnyvale CA, US
Joe Karratt - Millbrae CA, US
Steve Landreville - Mountain View CA, US
Eric Lang - Foster City CA, US
David Sanderson - Burlingame CA, US

David W. Snow - Menlo Park CA, US
Assignee:
Xtent, Inc. - Menlo Park CA
International Classification:
A61F 2/06
US Classification:
623 111
Abstract:
Apparatus for delivering stents to body lumens include a flexible catheter shaft, an expandable member, a tubular prosthesis selectively movable in an axial direction over the expandable member, and a stop member disposed on the catheter shaft near the distal end of the catheter shaft for stopping the prosthesis at a deployment position on the expandable member. A variety of different stop members are provided according to various embodiments, such as stop members disposed outside the expandable member, stop members disposed inside the expandable member, movable stop members, and the like. Methods of delivering stents are also provided.

In Situ Stent Formation

US Patent:
8460357, Jun 11, 2013
Filed:
May 31, 2005
Appl. No.:
11/142788
Inventors:
Michael C. McGarry - Truckee CA, US
Craig Welk - Tracy CA, US
Assignee:
J.W. Medical Systems Ltd. - Palo Alto CA
International Classification:
A61F 2/06
US Classification:
623 111, 623 121
Abstract:
Apparatus and methods for delivering stents and other prostheses to body lumens include a prosthesis forming and deploying mechanism carried at the distal end of a catheter shaft. The mechanism is adapted to form and deploy prostheses of a variable length, and to form and deploy multiple prostheses during a single interventional procedure.

Filed:
Jul 2, 2004
Appl. No.:
10/884616
Inventors:
Pablo Acosta - Newark CA, US
Bernard Andreas - Redwood City CA, US
Stephen Kao - Sunnyvale CA, US
Joe Karratt - Millbrae CA, US
Steve Landreville - Mountain View CA, US

US Classification:
623001110
Abstract:
Apparatus for delivering stents to body lumens include a flexible catheter shaft, an expandable member, a tubular prosthesis selectively movable in an axial direction over the expandable member, and a stop member disposed on the catheter shaft near the distal end of the catheter shaft for stopping the prosthesis at a deployment position on the expandable member.

Self-Constrained Segmented Stents And Methods For Their Deployment

View page
US Patent:
20060069424, Mar 30, 2006
Filed:
Sep 27, 2004
Appl. No.:
10/952568
Inventors:
Pablo Acosta - Newark CA, US
Craig Welk - Tracy CA, US
Jeffry Grainger - Portola Valley CA, US
Assignee:
Xtent, Inc. - Menlo Park CA
International Classification:
A61F 2/06
US Classification:
623001120, 623001160
Abstract:
A self-expanding stent includes a plurality of segments having a collapsed configuration and an expanded configuration. Preferably, the segments are unconnected to each other in at least the expanded configuration. The segments include restraining structures that temporarily restrain them from expansion until activated. This allows the user to position the desired number of segments at a treatment site and to deploy them simultaneously, thereby avoiding misalignment, overlap, and excessive spacing between segments. In preferred embodiments, multiple segmented stents of user-selectable length may be deployed at multiple locations in a single intervention.

Apparatus And Methods For Deployment Of Linked Prosthetic Segments

US Patent:
20070219612, Sep 20, 2007
Filed:
Mar 19, 2007
Appl. No.:
11/687885
Inventors:
Bernard Andreas - Redwood City CA, US
Sunmi Chew - San Jose CA, US
Jeremy Dittmer - Stanford CA, US
Jeff Grainger - Portola Valley CA, US
Stephen Kao - Sunnyvale CA, US
David Lowe - Redwood City CA, US
Bryan Mao - San Francisco CA, US
Steve Olson - Los Altos CA, US
David Snow - San Carlos CA, US
Craig Welk - Tracy CA, US
Assignee:
XTENT, INC. - Menlo Park CA
International Classification:
A61F 2/84
A61F 2/90
US Classification:
623 111, 623 116
Abstract:
A luminal prosthesis comprises a plurality of radially expandable prosthetic stent segments arranged axially. Two or more of the prosthetic stent segments are separable upon expansion from the remaining prosthetic stent segments and a coupling structure connects at least some of the adjacent prosthetic stent segments to each other. The coupling structure permits a first group of the adjacent prosthetic stent segments to separate from a second group of the prosthetic stent segments upon differential radial expansion of the first group relative to the second group and the coupling structure maintains or forms an attachment between the adjacent prosthetic stent segments in the first group which have been expanded together. A delivery system and methods for deploying the multiple coupled prosthetic stent segments are also disclosed.
