    Abstract: Valve delivery catheter assemblies including components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body. Catheter assemblies according to the present invention can include a handle assembly, an introducer sheath, and a distal tip assembly. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. A safety button can be included on the handle assembly to allow for precise and consistent positioning of the prosthetic valve in the body. A valve retaining mechanism can be included to assist in retaining the prosthetic valve prior to deployment.

    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.
