Filed:

Sep 29, 2009

Appl. No.:

12/569786

Inventors:

Duy Nguyen - Corona CA, US
Sheldon Nelson - Plymouth MN, US
Elizabeth Nee - Minneapolis MN, US
Guy P. Vanney - Blaine MN, US

Assignee:

St. Jude Medical, Atrial Fibrillation Division, Inc. - St. Paul MN

International Classification:

A61B 5/04
A61B 18/18
A61M 25/00
A61M 31/00
A61M 37/00

US Classification:

604528, 600374, 600585, 604523, 604 9504, 606 41

Abstract:

The invention provides a deflectable catheter capable of forming many variable radius spiral forms from a single, flexible, distal end section. In one aspect, the catheter employs a variable radius control wire to extend or deform a pre-formed loop structure into a three dimensional spiral-like form or geometry. The ability of a single catheter to create a multitude of shapes and sizes allows users to access to a number of anatomical areas without changing the catheter during a procedure or treatment. In another aspect, the invention encompasses methods of producing deflectable variable radius catheters, where two or more regions of the catheter having common control wires are fused or formed onto one another.

US Classification:

600486, 600481, 600485, 600488, 600492, 600509, 607 23

Abstract:

Disclose herein is a method of measuring pressures in a coronary sinus. In one embodiment, the method includes: introducing a distal portion of a lead or tool into the coronary sinus, wherein the distal portion includes first and second pressure sensors and at least one selectably expandable member; expanding the at least one expandable member such that the first and second sensors are isolated from each other within the coronary sinus; and taking pressure measurements with the first and second sensors when isolated from each other.

US Classification:

600373000, 600585000, 604523000

Abstract:

The invention provides a deflectable catheter capable of forming many variable radius spiral forms from a single, flexible, distal end section. In one aspect, the catheter employs a variable radius control wire to extend or deform a pre-formed loop structure into a three dimensional spiral-like form or geometry. The ability of a single catheter to create the multitude of shapes and sizes possible allows users to access a greater number of anatomical areas without changing the catheter during a procedure or treatment. In another aspect, the invention encompasses methods of producing deflectable variable radius catheters, where two or more regions of the catheter having common control wires are fused or formed onto one another.
