Abstract
A delivery device for a collapsible prosthetic heart valve includes an outer shaft having a first end and a second end, an inner shaft disposed inside the outer shaft and longitudinally movable relative to the outer shaft, and a distal sheath coupled to the inner shaft and movable with the inner shaft to selectively cover and uncover a compartment for housing the valve. The outer shaft includes a plurality of disks each having at least two hinges to allow articulation of adjacent disks relative to one another, and at least one rib for coupling the adjacent disks to one another.
Claims20
A delivery device for a collapsible prosthetic heart valve, the delivery device comprising:
- an outer shaft having a first end and a second end;
- an inner shaft disposed inside of the outer shaft and longitudinally movable relative to the outer shaft;
- and
- a distal sheath coupled to the inner shaft and movable with the inner shaft to selectively cover and uncover a compartment for housing the valve;
- the outer shaft including a plurality of disks, each disk having at least one hinge to allow articulation of adjacent disks relative to one another and at least one rib for coupling the adjacent disks to one another.
The method of claim 16, further comprising:
- a polymeric jacket disposed on an outer surface of the outer shaft.
A catheter comprising:
- an elongated tubular body having a first end and a second end and including a plurality of disks, each disk having at least two hinges to allow articulation of adjacent disks relative to one another and at least one rib for coupling adjacent disks to one another.
A method of forming a delivery device for a collapsible prosthetic heart valve comprising:
- providing an outer shaft having a first end and a second end, an inner shaft disposed inside of the outer shaft and longitudinally movable relative to the outer shaft, and a distal sheath coupled to the inner shaft and movable with the inner shaft to selectively cover and uncover a compartment for housing the valve;
- and
- cutting a series of circumferential patterns on the outer shaft at different axial lengths to form a plurality of disks, each disk having at least two hinges to allow articulation of adjacent disks relative to one another and at least one rib for coupling adjacent disks to one another.
