Abstract: A novel catheter is disclosed comprising an electrode array that is capable of switching between a sensing configuration for sensing electrical signals of biological tissue and an ablation configuration for delivery of ablation energy at a region of interest. Irrigation ports are interlaced within the electrode array to vent irrigant during an ablation procedure to; prevent excessive heating, charring of tissue, coagulation of blood, and allow for efficient delivery of ablation therapy for maximum therapy efficacy. The novel catheter includes a plurality of splines with linear portions wherein the electrodes of the electrode array are disposed. The splines are connected by connectors which include one or more bends capable of storing potential energy when the bends are elastically deformed, enabling collapse and expansion of the catheter in a sheath.

Abstract: An implant removal device for removal of ruptured silicone breast implants includes a hollow container having a middle portion disposed between a first end and a second end. The device also has a connector port coupled to the second end that is coupled to a suction device during use. The device also includes a nozzle coupled to the first end that is configured for placement against an incision of a patient for removing a ruptured breast implant from the patient. The positioning of the nozzle on said first end is offset from a longitudinal axis that extends in a direction parallel to the length of the middle portion and within the middle portion. The nozzle opening may include gripping portions for aiding in gripping the implant shell during the removal process.

Abstract: An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical rings generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting links placed so that the stent is flexible in the longitudinal direction. The link pattern is optimized to reduce strain on the links and enhance longitudinal flexibility and security of the stent. The stent includes a distal end ring and a proximal end ring that have a length that is shorter than the length of the body rings.
