摘要： A steerable catheter and methods of fabrication including a catheter body (12) formed of a continuous wire braid formed of wires braided over a delivery lumen (24) liner and a pull wire lumen (26) liner distal to a pull wire jacket port (32), braided around the pull wire jacket port to form a braid port (90), and over at least a portion of the delivery lumen liner proximal to the pull wire jacket port. A pull wire (30) extends from a pull wire proximal end through the pull wire lumen port and through the pull wire lumen to a pull wire distal end. A band is attached to the pull wire distal end and fitted over a distal segment of the wire braid proximal to the catheter body distal end to fix the pull wire distal end to the catheter body.

摘要： A non-sheath based medical device delivery system is provided including an elongated tubular guide body (10) having a distal end (14) fixedly attached to a resilient collet (18) with a longitudinal opening to receive a medical lead or other device. The collet may be opened by actuating a retraction member (26) to cause the closing member (22) to slide proximally along the collet shaft, allowing the collet to maintain a normally open position. With the collet closed, the device may be advanced to a desired internal body location by advancing the guide body. The majority of the device body will be exposed, running alongside the guide body, allowing any sensors or electrodes located on the device body to be fully operational during the implantation procedure. The delivery system may be removed by opening the collet, to slidably disengage from the device body.
