20130190688CATHETER AND CATHETER ARRANGEMENT - A catheter with an elongated catheter body which, with regard to a position of use, has a distal and a proximal end, wherein at the distal end, a sponge- or cushion-like elastic deformation body is arranged which has, in particular, electrically, mechanically or optically acting measuring means or a measuring connection for detecting a pressing force exerted on the deformation body.07-25-2013
20130197432MEDICAL DEVICE SYSTEM AND METHOD FOR PUSHABILITY - Medical device system comprising a catheter including an elongate tubular member having an inner wall surface defining a lumen extending longitudinally through at least a portion of the tubular member. The medical device also includes an inner stop extending inwardly from the inner wall surface of the tubular member at a distal end section of the catheter and a pusher device insertable into the lumen. The pusher device has a contact surface to abut the inner stop of the tubular member.08-01-2013
20130204184KERSTPIEK TIP FOR MEDICAL DEVICES - An apparatus may include a medical device including an elongate shaft disposed about a guidewire, and a distal tip including a plurality of rounded protrusions, wherein adjacent protrusions are fixed directly to each other by a discrete, relatively flexible connector. The plurality of protrusions may each decrease in size from a proximalmost protrusion distally to distalmost protrusion.08-08-2013
20120083732CATHETER WITH A POLYMIDE DISTAL TIP - A catheter having an elongated shaft which has a multilayered distal tip with a first layer formed of a polyimide first material and a second layer formed of a polymeric second material. In one embodiment the multilayered distal tip is a separate member, distal to the distal end of a proximal portion of the shaft. In another embodiment, the shaft has an outer tubular member, and a multilayered inner tubular member with a distal end which forms the multilayered distal tip of the shaft. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. In one embodiment, the polymeric second material is a polyamide material.04-05-2012
20120095395APPARATUS AND PROCESSES FOR APPLYING SUBSTANCES WITHIN MAMMALIAN TISSUE - An apparatus for applying a substance to internal mammalian tissue is provided. The apparatus includes a member having a flexible, absorbent, porous portion connected to a non-porous portion. The apparatus may be used to treat atrial fibrillation or other non-atrial fibrillation issues with internal mammalian tissue.04-19-2012
