International Classification:

A61F 2/06

US Classification:

623 111, 623 112, 606108, 606200

Abstract:

A catheter system and method for implanting an endoprosthesis such as a stent at a treatment site in a patient's body lumen. The catheter provides a complete system for stent delivery, dilatation, and delivery and/or recovery of an expandable device, such as an embolic protection device, adjacent to the treatment site in the body lumen.

US Classification:

623 111, 623 112, 606108, 606198, 606200

Abstract:

A catheter system for implanting an endoprosthesis at a treatment site in a patient's body lumen. The catheter includes an elongated shaft outer member and a stent sheath distal portion and a self-expanding stent radially restrained in a collapsed configuration within the stent sheath distal portion. A balloon catheter dimensioned for relative axial movement within the shaft outer member has an elongated shaft having an inflation lumen and a device receiving lumen. A stent stop secured to the balloon catheter is reversibly radially expandable to deploy from a collapsed to a radially expanded configuration. In the expanded configuration, the stent stop prevents longitudinal displacement of the stent. A balloon is located on a distal shaft section is releasably locked with respect to the shaft outer member and slidably disposed therein in an unlocked configuration.

International Classification:

A61F 2/24

US Classification:

623 236, 623 211

Abstract:

Disclosed are devices and methods for treating regurgitation through a valve in the heart. The devices can include an expandable, fluid-tight bladder configured to be deployed between valve leaflets of the heart valve. The bladder can include an upper portion that extends into the atrium of the heart; a lower portion that extends into the ventricle of the heart; and a middle portion positionable within the line of valve leaflet coaptation that provides a sealing surface for one or more of the leaflets.

Appl. No.:

11/353391

Inventors:

Alexander Nikanorov - Palo Alto CA, US
Keif Fitzgerald - San Jose CA, US
Steven Tyler - Portola Valley CA, US
Boris Anukhin - San Jose CA, US

International Classification:

A61F 2/06

US Classification:

623001150

Abstract:

An expandable stent has larger cells located at the distal end of the stent than in the body portion so that a catheter balloon can more easily protrude into the cells to increase stent retention relative to the balloon. The intravascular stent has a plurality of cylindrical rings connected by links, the spacing of which is a factor in defining the cell size. The stent can be compressed or crimped onto a balloon catheter to a very low profile and maintain a high degree of stent retention due to increased spacing between rings in the region of the distal end ring.

International Classification:

A61F 2/24

US Classification:

623 237

Abstract:

Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.

International Classification:

A61B 17/03

US Classification:

606151

Abstract:

The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.
