Abstract: A system (100) includes a handle (130), a sheath (122) attached to and distally extending from the handle (130), and a tubular component (102) slidingly disposed within the sheath (122). The handle (130) includes a locking mechanism (140) including an unlocked state in which the tubular component (102) is permitted to slide and rotate freely relative to the sheath (122), a locked state in which the tubular component (102) is not permitted to slide or rotate relative to the sheath (122), a first semi-locked state in which the tubular component (102) is permitted to slide freely relative to the sheath (122) and is not permitted to rotate freely in a circumferential direction relative to the sheath (122), and a second semi-locked state in which the tubular component (102) is not permitted to slide freely in a longitudinal direction relative to the sheath (122) and is permitted to rotate freely in a circumferential direction relative to the sheath (122).

Abstract: A catheter shaft includes a proximal portion with a first polymer having a first stiffness and a first portion of a tubular braid component extending within the first polymer, an intermediate portion with a second polymer having a second stiffness and a second portion of the tubular braid component extending within the second polymer, and a distal portion with a third polymer having a third stiffness, a third portion of the tubular braid component extending within the third polymer, and a hypotube extending within the third polymer. The hypotube is configured for elastic deformation and includes a sidewall cut with a pattern. Along an overlap segment of the distal portion, the third portion of the tubular braid component and the hypotube overlap each other. The outer shaft is configured for improved torque transmission.

Abstract: A balloon catheter configured for delivery of a prosthetic heart valve is provided. The balloon catheter is configured to deploy a prosthetic heart valve through inflation. The balloon catheter is provided with a reinforcing member configured to increase the rigidity of the balloon catheter over an operational portion of the device. The increased rigidity serves to prevent damage to an introducer sheath, patient anatomy, or the prosthetic heart valve during delivery of the prosthetic heart valve.
