摘要:
A method for passivating a biomaterial surface includes exposing the biomaterial surface to therapeutic electrical energy in the presence of blood or plasma. The biomaterial surface may be removably secured within a chamber of a treatment system, which communicates the therapeutic electrical energy to the biomaterial surface while interfacing the biomaterial surface with blood or plasma.

A system for minimizing and/or eliminating coagulative or mineral deposits on respective blood-contacting surfaces of implanted medical devices includes an implantable system having a current generating device that is electrically coupled to at least first and second electrodes for developing a current therebetween. The at least first and second electrodes are disposed across a patient's thoracic cavity in a manner so that a particular implanted medical device having at least a portion thereof that is fabricated from an electrically conductive material is disposed in a path substantially between such electrodes, thereby focusing the generated electrical current at the electrically conductive portion of the implanted medical device for therapeutic treatment thereat.

A deflectable sheath with increased range of curvature for human use is provided. The improvement focuses on the use of different durometer polymers that compose the lumen in the portion of deflection. The use of differing durometer polymers allow the deflectable sheath to be bent in a multitude of asymmetric curvature radii therefore providing the physician with a sheath that can traverse different regions of the body than with previous sheaths.

摘要:
A medical balloon for attachment to a catheter tube, and method of making the balloon. The balloon comprises a plurality of co-extruded and coextensive layers of different polymeric materials (20A, 20B) at least one of which is a base structural layer (20B) and the other of which (20A) is formed of polyethylene and copolymers thereof or of Selar. The base structural layer is thicker than the other layer.

A catheter includes a shaft including a proximal end and a distal end, an electrical conductor coupled to the catheter, and an electrode coupled to the electrical conductor. The electrode includes at least one recessed portion, and an impedance reduction layer disposed in the at least one recessed portion. The impedance reduction layer has a thickness less than a depth of the recessed portion.
