US Patent:

20120035708, Feb 9, 2012

Filed:

Aug 3, 2011

Appl. No.:

13/197511

Inventors:

Richard A. Swift - South Bend IN, US
Oliver Bach - Neuenburg, DE
Ralf Steiner - Pforzheim, DE

Assignee:

Cook Medical Technologies, LLC - Bloomington IN

International Classification:

A61F 2/82

US Classification:

623 116

Abstract:

A perfusion device and a delivery system for repair of a damaged portion of a body vessel. Perfusion device can include a tubular body that is self-expandable, having a proximal portion, a distal portion, and an intermediate portion. One or more series of barbs can be disposed circumferentially along the intermediate portion. Barbs are capable of penetrating into the tunica intima and tunica media of said vessel wall upon insertion of said device into said body vessel, and not into said tunica adventitia. A graft can be associated with the tubular body. Graft has a proximal end and a distal end, and preferably extends entirely along a luminal wall of the tubular body. Graft may also extend along an exterior surface of the tubular body at the proximal and distal portions. A remodelable covering can be applied along the intermediate portion. Delivery devices for the perfusion implant and methods of delivering the perfusion implant are also provided.

International Classification:

A61F 2/915
A61F 2/844

Abstract:

The present disclosure describes intraluminal support devices having high radial stiffness regions with smaller diameter and low radial stiffness regions with larger diameter. When deployed to the vasculature of a patient in need of treatment, the high radial stiffness region is sized such that it has approximately the diameter of the vessel in need of treatment, so that it produces substantially zero chronic radial force when the vessel is not being subjected to external compression. The low radial stiffness regions anchor the device to the vessel wall and provide a less-abrupt transition from the high radial stiffness structure. Methods of making and using such devices are also described.

Appl. No.:

16/207391

Inventors:

Richard Swift - South Bend IN, US
Shuo Yang - West Lafayette IN, US
Tracy Willis - Bloomington IN, US
Gary Neff - Bloomington IN, US

International Classification:

A61M 25/09
A61B 5/055
G01R 33/28

Abstract:

The disclosure relates to medical devices and methods of assembling medical devices, such as MRI-compatible interventional wireguides. An example of a wireguide includes a series of individual segments, a plurality of connectors, and a plurality of spacers. Each segment in the series of individual segments has a first end and a second end. Each connector of the plurality of connectors joins adjacent segments in the series of individual segments to one another such that a first end of a first segment and a second end of a second segment in the series of individual segments are attached to a connector of the plurality of connectors. A spacer of the plurality of spacers is disposed between each pair of adjacent segments in the series of individual segments. Each of the segments in the series of individual segments is electrically insulated from an adjacent segment in the series of individual segments.

Inventors:

- Bloomington IN, US
Richard A. Swift - South Bend IN, US
Conor Dillon - Co. Tipperary, IE

International Classification:

A61F 2/915

Abstract:

Disclosed herein is an intraluminal support device including a closed cell design on at least one end of the device. In such a device, the closed cell structure is formed by connecting all peaks of an ultimate ring to all peaks of a penultimate ring, and all valleys of the ultimate ring to all valleys of the ultimate ring. The support device expands evenly due to this structure.

International Classification:

A61F 2/915
A61F 2/844
A61F 2/958

Abstract:

Examples of a stent is provided with interlocking joints removably coupling adjacent axial stent segments. Mating elements forming the interlocking joints maintain circumferential and axial engagement when the stent is in the radially compressed configuration, for example, during tracking of the stent to a treatment site of a body vessel, and become disengaged during radial expansion of the stent. The length of mating elements may be sized as large as the strut width. When disengaged, the disconnected the axial stent segments remain discrete stent structures separated from one another along the point of treatment.
