Filed:

Oct 28, 2005

Appl. No.:

11/260981

Inventors:

Thomas A. Osborne - Bloomington IN, US
Charles W. Agnew - West Lafayette IN, US
Brian C. Case - Bloomington IN, US

Assignee:

Cook Incorporated - Bloomington IN

International Classification:

A61F 2/06

US Classification:

623 126, 623 214, 623 216

Abstract:

Prosthetic valves for regulating fluid flow through a body vessel are described. The valves include a valve member that includes at least a portion that is capable of moving to selectively permit and substantially prevent fluid flow through the body vessel, either alone or with one or more additional valve members. A cannula is associated with the valve and permits a controlled amount of fluid flow through the valve, such as retrograde flow while the valve member substantially prevents fluid flow through the body vessel.

International Classification:

A61F 2/06

US Classification:

623 136, 427 224, 623 146

Abstract:

Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device can include a frame with one or more projections each having at least one edge extending from the surface of the frame, and a biocompatible, water-soluble removable material coated over at least a portion of the at least one edge. The projections can be barbs positioned to engage the interior wall of a body vessel or to attach a material, such as a valve leaflet or graft, to the frame. The removable material can be dissolved within a body vessel upon implantation, thereby exposing the at least one edge. Methods of making an implantable medical device and methods of treating a subject are also disclosed.

International Classification:

A61F 2/06

US Classification:

623 136, 623 115

Abstract:

A medical prosthesis for implantation within the body of a patient comprises a support structure and an anchoring element that comprises a basal portion and at least one barb extending from the basal portion. The anchoring element may be slidably attached to the strut and the strut may include a first stop and a second stop that define a longitudinal zone of movement for the anchoring element. Other devices and methods are described.

Appl. No.:

11/103137

Inventors:

Brian C. Case - Bloomington IN, US
Jacob A. Flagle - Bloomington IN, US
Charles W. Agnew - West Lafayette IN, US

Assignee:

Cook Incorporated - Bloomington IN

International Classification:

A61F 2/06

US Classification:

623 124

Abstract:

Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. Embodiments of the invention relate to medical devices comprising a frame having a compliance that can change upon implantation of the medical device within the lumen of a body vessel. Controlled fracture or bioabsorption of frame material can, in some embodiments, increase the compliance of a frame after implantation. Medical devices comprising a frame and one or more valve members adapted to regulate fluid flow in a body vessel, such as a vein, are also provided.

Appl. No.:

11/708860

Charles W. Agnew - West Lafayette IN, US

Assignee:

Cook Incorporated - Bloomington IN

International Classification:

A61F 2/06
A61F 2/24
A61F 2/86

US Classification:

623 124, 623 21, 623 212

Abstract:

Methods of reducing retrograde fluid flow through a valve within a body vessel are provided. The methods can include the steps of identifying a valve exhibiting an undesirable amount of retrograde fluid flow within a body vessel, such as a venous valve or a heart valve, and providing a means for reducing the retrograde fluid flow. A medical device providing a desired amount of retrograde fluid flow can be modified after permitting the medical device to remain in a body cavity for a remodeling-effective time period. The implanted medical device can be modified by subsequently reducing the amount of retrograde fluid flow permitted across the implanted prosthetic valve within the body vessel.

Assignee:

Cook Medical Technologies LLC - Bloomington IN

International Classification:

A61F 2/06

US Classification:

623 124, 623 233

Abstract:

Prosthetic valves, methods of making medical devices, and methods of treatment are provided. The prosthetic valves of the invention have a valve portion moveable between first and second positions, and a spacing member that has a thickness and protects a portion of the valve portion from contact with a wall of a vessel in which the prosthetic valve is implanted, and/or another structural component of the prosthetic valve, such as a support frame.
