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.

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.

Appl. No.:

12/114616

Inventors:

Elizabeth Nee - Chicago IL, US
Thao Thu Nguyen - South Bloomington MN, US
Scott Salys - Los Angeles CA, US

Assignee:

PACESETTER, INC. - Sylmar CA

International Classification:

A61N 1/05

US Classification:

607116

Abstract:

Disclosed herein is a tool for implanting a medical lead. In one embodiment, the tool includes a body, an electrode, and a conductor. The body includes a distal end and a proximal end. The electrode is supported by the body. The conductor is in electrical contact with the electrode and extends along the body from the electrode to the proximal end. The electrode and conductor form an electrically conductive path that extends from a surface of the electrode to a proximal most point of the conductor on the body. The electrical resistance of the electrically conductive path is at least approximately 100 Ohms.

International Classification:

A61B 17/00

US Classification:

606129

Abstract:

An implant tool for use with an endocardial or other implantable lead having an extendable/retractable active fixation tip includes a housing, a shaft rotatably supported by the housing, and a shaft rotation mechanism for rotating the shaft through a predetermined angular travel. The shaft includes a lead attachment portion for selectively coupling a lead to the shaft such that the lead is rotatable with the shaft. The implant tool may include a control tab slidably supported by the housing, wherein longitudinal movement of the control tab actuates the shaft rotation mechanism. The shaft rotation mechanism may include a gear train, an electric motor, a double acting spring mechanism, or a retractable tape wound around the shaft. The gear train includes an input member coupled to the control tab and an output gear coupled to the shaft. The input member meshes with an input gear supported by the housing.
