Filed:

Jan 23, 2006

Appl. No.:

11/338031

Inventors:

Bradford A. Bjorkman - Elk River MN, US
Daniel J. Potter - Stillwater MN, US
Donald G. Goblish - Cologne MN, US

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61M 5/14
F16K 1/48

US Classification:

604256, 251369, 60416405

Abstract:

The present invention is a tool coupled to a hemostasis valve and adapted to slit/split a tubular body of a catheter or sheath to facilitate the removal of the tubular body from about a medical device extending through the hemostasis valve and tubular body. The tool comprises a conical barrel portion supporting one or more radially outward extending blades. The tool also comprises a stabilizing component for preventing displacement between the tool and medical device when the tubular body is being removed from about the medical device.

A61B 18/14

Abstract:

The present disclosure provides electroporation systems, methods of controlling electroporation systems to limit electroporation arcs through intracardiac catheters, and catheters for electroporation systems. One method of controlling an electroporation system including a direct current (DC) energy source, a return electrode connected to the DC energy source, and a catheter connected to the DC energy source is disclosed. The catheter has a at least one catheter electrode. The method includes positioning the return electrode near a target location within a body and positioning the catheter electrode adjacent the target location within the body. A system impedance is determined with the return electrode positioned near the target location and the catheter electrode positioned within the body. The system impedance is adjusted to a target impedance to arcing from the catheter electrode.
