Abstract
A delivery device for a collapsible prosthetic heart valve includes an inner shaft having a proximal end and a distal end, an outer shaft disposed around the inner shaft and longitudinally moveable relative to the inner shaft, and a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment being adapted to receive the prosthetic heart valve. At least one of the outer shaft or the distal sheath may have a pattern of cutouts formed therein, the pattern including at least one ring around a circumference of the at least one of the outer shaft or the distal sheath, the at least one ring having at least one of the cutouts.

A delivery device for a collapsible prosthetic heart valve comprising:
- an inner shaft having a proximal end and a distal end;
- an outer shaft disposed around the inner shaft and longitudinally moveable relative to the inner shaft;
- and
- a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment being adapted to receive the prosthetic heart valve;
- at least one of the outer shaft or the distal sheath having a pattern of cutouts formed therein, the pattern including at least one ring around a circumference of the at least one of the outer shaft or the distal sheath, the at least one ring having at least one of the cutouts.
A delivery device for a collapsible prosthetic heart valve, the delivery device comprising:
- an inner shaft having a proximal end and a distal end;
- an outer shaft disposed around the inner shaft and longitudinally moveable relative to the inner shaft;
- and
- a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment being adapted to receive the prosthetic heart valve;
- at least one of the outer shaft or the distal sheath having a pattern of cutouts formed therein, the pattern including a plurality of polygonal cells extending through the at least one of the outer shaft or the distal sheath.
A method of forming a delivery device for a collapsible prosthetic heart valve comprising:
- providing an inner shaft having a proximal end and a distal end, an outer shaft disposed about the inner shaft and being longitudinally moveable relative to the inner shaft, and a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment being adapted to receive the prosthetic heart valve;
- and
- cutting a pattern on at least one of the outer shaft or the distal sheath at different axial extents.
