An electrophysiology catheter which includes: a catheter tube having a band of electrically conductive material extending around substantially the entire circumference of the catheter tube, the conductive material being non-adhesive; a flexible electrical conductor within the catheter tube, the elec ...
Invasive medical catheters with distal end assemblies having a protective surface coating bonded thereto are constructed by applying a hydrophilic primer to at least a portion of a tubular polymer body. The primer coating chemically bonds to the polymer substrate by developing covalent bonding or cr ...
A mapping catheter includes an elongated body for inserting into patient vasculature. A distal end of the elongated body includes a distal portion that includes a plurality of electrodes, a proximal portion disposed proximal to the distal portion, and a reduced-dimension portion disposed between the ...
An embodiment of an open-irrigated catheter system comprises a tip section, a distal insert, and mapping electrodes. The tip section has an exterior wall that defines an open interior region within the tip section. The exterior wall includes mapping electrode openings and irrigation ports. The exter ...

An embodiment of a mapping probe assembly includes a body frame with a lumen therein. The body frame includes a catheter shaft region, a loop section and a transition region between the catheter shaft region and a loop section. A plurality of mapping electrodes are attached around the loop section. ...
Disclosed herein, among other things, are methods and apparatus related to radio frequency (RF) ablation catheters. The present subject matter provides a method for forming an ablation catheter having a balloon at a distal end of the catheter. The method includes applying a band of conductive materi ...
Discloses herein are ablative catheters and methods of use. The catheters can include a cooling chamber for circulating cooling fluid within the catheter tip to reduce hot spots within the catheter tip and/or to reduce the formation of coagulum. A proximal cooling chamber can be positioned proximall ...
A medical device system includes an elongated body with a distal end that is configured and arranged for insertion into a patient. A housing is disposed in the distal end of the body. A rotatable magnet is disposed in the housing. At least one magnetic field winding is configured and arranged to gen ...
