US Patent:

7963960, Jun 21, 2011
Filed:

Nov 7, 2006
Appl. No.:

11/557204
Inventors:

Walter Bruszewski - Guerneville CA, US
Patrick Macaulay - Windsor CA, US
Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61B 18/14
US Classification:

606 32, 606 41, 606 45, 606 46
Abstract:

RF power is applied to a circular RF electrode cutting a side opening in a graft material of a main stent-graft in situ. As the side opening is formed by the applied RF power and the associated plasma discharge, the side opening is formed with a minimal application of force to the graft material. Further, the side opening is circular and has a fused edge.

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61F 2/06
US Classification:

623 113, 623 136
Abstract:

A stent graft system and method of use includes a stent graft for fixation at an attachment site with graft material defining at least one opening having an opening perimeter; a support attached to the graft material; a guide rail attached around the opening perimeter; and a helical anchor having a plurality of coils with a point at one end. The plurality of coils are rotatable around the guide rail to cause the pointed end of the coils to penetrate the graft material and the adjacent tissue in contact with the stent graft to sew the stent graft to the attachment site.

US Patent:

8052741, Nov 8, 2011
Filed:

Mar 23, 2009
Appl. No.:

12/409012
Inventors:

Walter Bruszewski - Guerneville CA, US
Masoumeh Mafi - Mountain View CA, US
Shahram Shamlou - Mountain View CA, US
Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61F 2/06
US Classification:

623 135, 606153
Abstract:

A branch prosthesis configured for placement in a branch vessel includes an expandable tubular body portion, an expandable annular flange attached to a proximal end of the body portion, and a sealing sleeve proximally extending from the annular flange. The sealing sleeve is adapted to deform to a generally straight cylindrical hollow shape during implantation. When deployed, the sealing sleeve rolls up to a tightly-wound coil that bears against the annular flange. When used in conjunction with a main prosthesis having a side opening and deployed within in a main vessel, the annular flange of the branch prosthesis engages an outer surface of the main prosthesis around a perimeter of the side opening and the sealing sleeve engages an inner surface of the main prosthesis around the perimeter of the side opening to form a fluid-tight seal between the main prosthesis and the branch prosthesis.

Bloused Stent-Graft And Fenestration Method

US Patent:

8100960, Jan 24, 2012
Filed:

Mar 20, 2008
Appl. No.:

12/052591
Inventors:

Walter Bruszewski - Guerneville CA, US
Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61F 2/06
US Classification:

623 113
Abstract:

A method includes deploying a bloused stent-graft into a main vessel such that a bloused section of the bloused stent-graft covers a branch vessel emanating from the main vessel. The bloused section includes loose graft cloth. A pressure differential between the main vessel and the branch vessel causes the bloused section to be forced into an ostium of the branch vessel creating a pocket aligned with the branch vessel. A distal tip of a puncture device is located in the pocket and thus aligned with the branch vessel. An outward force is applied to the puncture device to cause the distal tip of the puncture device to fenestrate the bloused section thus creating a collateral opening in the bloused section precisely aligned with the branch vessel.

Method And Structure For Ameliorating Side-Effects Of Performing In Situ Fenestration Using A Plasma Rf Catheter

US Patent:

8197475, Jun 12, 2012
Filed:

Mar 17, 2008
Appl. No.:

12/049522
Inventors:

Walter Bruszewski - Guerneville CA, US
Trevor Greenan - Santa Rosa CA, US
Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61B 18/18
A61B 18/04
US Classification:

606 41, 606 34, 623 132
Abstract:

When a main stent-graft is placed in a vessel of a patient and a branch vessel is blocked by the main stent-graft, a RF plasma catheter is used to cut out a portion of the graft cloth of the main-stent graft adjacent to an ostium of the branch vessel to be perfused. To ameliorate possible adverse effects associated with the use of the RF plasma catheter, e. g. , creation of coagulum, (desiccated, coagulated blood) or perhaps a cut stent strut, a special process using saline flushing, a novel RF plasma catheter with an insulated tip, or a combination of the two is used.

US Patent:

8292885, Oct 23, 2012
Filed:

Apr 21, 2008
Appl. No.:

12/106677
Inventors:

Walter Bruszewski - Guerneville CA, US
Masoumeh Mafi - Santa Rosa CA, US
Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61B 18/18
US Classification:

606 45, 606 41, 623 111
Abstract:

To facilitate the widespread use of the RF plasma catheter to provide in situ fenestration of a main stent-graft, potential side-effects of the fenestration are ameliorated using an electrode from a family of electrodes. Specifically, a family of electrodes is provided so that for a particular application, an appropriate electrode can be selected.

Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:

A61F 2/06
US Classification:

623 135, 623 113, 623 115
Abstract:

An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, a forms a lumen therethrough. The mobile external coupling extends outwardly from the tubular body. The mobile external coupling includes a graft material and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top, wherein the coupling lumen is in flow communication with the body lumen. A cylindrical sealing cuff of graft material is attached to and extends from the top of the mobile external coupling towards the tubular body within the coupling lumen. The sealing cuff is configured to contact a portion of a branch vessel prosthesis and thereby provides an elongated interference seal between the branch vessel prosthesis and the mobile external coupling.
