摘要：
A catheter for delivering a medical device to an implant site within a receptacle of a distal-most portion thereof, includes a coiled spring member, which has one or more proximal turns, secured to a shaft proximal portion, one or more distal turns, secured to the distal-most portion, and a plurality of open-pitch turns that extend between the proximal and distal turns and are, preferably, pre-loaded by longitudinal compression prior to forming a sheath thereover. A deflection assembly pull wire extends through a lumen of the shaft proximal portion and alongside the plurality of open-pitched turns of the spring member, wherein a pull wire proximal end extends proximally out from a proximal opening of the lumen of the proximal portion and into a handle of the catheter, for coupling to a control member subassembly, and a pull wire distal end is secured to the shaft distal-most portion.
