Abstract
Disclosed herein are embodiments of stabilizers for use in delivering a replacement heart valve. The stabilizers can receive a portion of a delivery system, such as a handle, to prevent unwanted motion of the delivery system. The stabilizer can include a linear actuator for adjusting a position of the delivery system once held within the stabilizer.
Claims18
A stabilizer for a heart valve delivery system, the stabilizer comprising:
- an elongated main body comprising a proximal end and a distal end and a longitudinal axis extending between the proximal end and the distal end, the elongated main body comprising:
- a generally flat base plate extending between the proximal end and the distal end;
- a first angled surface located on top of the base plate, the first angled surface being sloped downwardly toward the distal end;
- and
- a second angled surface located on top of the base plate and spaced longitudinally away from and proximal of the first angled surface, the second angled surface being sloped downwardly toward the distal end;
- a hub nest attachable on top of the first angled surface, the hub nest comprising an extension extending upwards from the first angled surface, the extension configured to releasably hold a sheath hub of the heart valve delivery system;
- a handle carriage on top of the second angled surface, the handle carriage comprising a track attachable to the second angled surface and a heart valve delivery system clamp configured to longitudinally travel along the track, wherein the heart valve delivery system clamp is configured to releasably hold a handle of the heart valve delivery system;
- and
- a base adapter, wherein the distal end of the main body is configured to releasably connect with the base adapter,
- wherein:
- the base adapter comprises a pair of proximally extending arms and an upper tab configured to receive distally extending tabs of the main body to prevent upward motion of the main body;
- the first angled surface and the second angled surface are configured to be individually angularly adjusted with respect to the flat base plate;
- the handle carriage comprises a first knob configured to longitudinally translate the heart valve delivery system clamp along the track and a second knob configured to open and close the heart valve delivery system clamp;
- and
- the first angled surface has a lower height relative to the flat base plate than the second angled surface.

- a travel screw located within the track, wherein a portion of the heart valve delivery system clamp is located within the track and interfaces with the travel screw to cause longitudinal travel of the heart valve delivery system clamp along the track;
- and
- a base adapter, wherein the distal end of the main body is configured to releasably connect with the base adapter.

- detachable clamps to allow attachment of the main body to the base before or after starting a delivery procedure;
- and
- a second base adapter, wherein the proximal end of the main body is configured to releasably connect with the second base adapter.
