6383198, May 7, 2002

Filed:

Dec 7, 1999

Appl. No.:

09/456835

Inventors:

Peter Hamilton - East Bridgewater MA

Assignee:

SciMed Life System, Inc. - Maple Grove MN

International Classification:

A61B 1900

US Classification:

606115, 606110

Abstract:

A grabbing device includes a transparent flexible cup that can be placed adjacent to a selected region of an inner surface of a body cavity. The flexible cup is visually put in place by the surgeon, and a vacuum is applied to draw a selected amount of tissue into the flexible cup, so that it may, e. g. , be excised. The device may also retrieve the tissue excised from the body cavity.

International Classification:

A61M 5178

US Classification:

604158, 60416413, 604159, 600585

Abstract:

An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire. The apparatus includes a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device for connecting the guidewire to the extension guidewire. The connecting device is configured for mating with the steering device to form an integral unit. The invention further includes a method of inserting a guidewire in a body and connecting the guidewire to an extension guidewire. The method includes the steps of: providing an integral guidewire holder and tool for connecting a guidewire to an extension guidewire; gripping the guidewire with the integral guidewire holder; inserting the guidewire into a body lumen; displacing the integral guidewire holder and tool relative to the guidewire so that the proximal end of the guidewire is located in a slot of the integral guidewire holder and tool; inserting an extension guidewire into the slot of the integral guidewire holder and tool; and connecting the guidewire to the extension guidewire. The method further includes the step of aligning the guidewire and extension guidewire in the slot prior to the connecting step.

International Classification:

A61F 206

US Classification:

623 111, 623 112

Abstract:

The present invention relates to a system for delivering a medical prosthesis into a body lumen. A preferred embodiment of the invention utilizes a catheter having a stent mounted at the distal end that is released into the body lumen by movement of an outer sheath covering the stent in the proximal direction. The stent expands to conform to the inner wall of the lumen and the catheter is withdrawn.
