US Patent:

6409737, Jun 25, 2002

Filed:

Oct 8, 1999

Appl. No.:

09/645987

Inventors:

Richard C. Fortier - Concord MA
Susan M. Ostrowski - Arlington MA

Assignee:

Scimed Life Systems, Inc. - Maple Grove MN

International Classification:

A61B 1712

US Classification:

606140, 606139, 606151, 606157

Abstract:

An improved elastic band for ligating tissue within a living body comprises a central opening defining an axis. A first curved edge is formed between a first surface extending substantially parallel to the axis and a second surface extending substantially perpendicular to the axis. A method of ligating tissue within a living body using such a ligating band comprises the steps of positioning the elastic band, which has been stretched to increase the size of a central opening extending therethrough, adjacent to a portion of tissue to be ligated. The tissue to be ligated is then drawn through the central opening of the elastic band and the elastic band is released so that the size of the central opening decreases to grip the tissue received therein.

US Classification:

604540, 604 8, 604544, 604523

Abstract:

A single operator drainage catheter delivery system and method of use. The delivery system includes a guide member having a guidewire lumen extending through a distal portion thereof, with a proximal guidewire port located distal of the proximal end. A placement catheter disposed over the guide member has a catheter lumen extending through a distal portion thereof, with a proximal guidewire port located distal of the proximal end. Locating the proximal guidewire ports as such allows the delivery system to be used by a single person with a shorter guidewire. A drainage catheter is disposed about the guide member distal of the placement catheter. The drainage catheter delivery system preferably includes a means for releasably connecting the placement catheter to the drainage catheter, wherein the releasable connecting means disconnects the drainage catheter upon displacement of the guide member.

International Classification:

A61B 18/18

US Classification:

606 14

Abstract:

A method for treating a cardiac condition with visual inspection of a tissue treatment site includes the step of delivering an expanding member formed on a distal end of a catheter to a position adjacent a tissue treatment area within a patient's heart. The expandable member has an elastic portion configured to conform to the tissue treatment area. The method further includes the steps of expanding the expandable member thereby allowing the elastic portion of the expandable member to conform to the tissue treatment area and positioning an energy emitter at a first location within an inner lumen of the catheter. A visible aiming beam is projected during positioning of the energy emitter and ablative energy is delivered from the energy emitter to the tissue treatment area thereby resulting in a first spot lesion. The ablative energy is coincident with the aiming beam and the aiming beam is in the form of pulsed visible light to allow intermittent visual inspection of the first spot lesion at times when the aiming beam is not projected onto the tissue treatment area, thereby allowing visual inspection of the ablative characteristics and sufficiency of the first spot lesion.

US Classification:

Abstract:

A transducer assembly, suitable for medical examinations, for generating an apodized sector shaped beam of energy. A transducer in the form of a crystal, has a ring-like structure on its face which apodizes the signal produced by the transducer by providing a greater amount of attenuation at the transducer's periphery than at the transducer's center.
