Abstract
Medical devices for delivering stents, prosthetic valve devices, and other implantable articles inside a patient's body are provided. The devices have an elongate inner compression member having a proximal end and a distal mating end with a tapered portion and outer engaging surface, a first portion proximal to the distal mating end, and the tapered portion having a smaller cross sectional area than the first portion and being more flexible than the first portion. The devices further have an inner guide channel member with a first end and a second end defining a channel of substantially uniform inner diameter, the second end having an outer diameter, and the first end having a taper extending from the second end outer diameter to a smaller second outer diameter. A joint is configured for melt bonding or implanting the inner compression member distal mating end and the inner guide channel member second end.
