Valve prosthesis deployment assembly and method
First Claim
1. A prosthesis delivery system comprising:
- a handle assembly comprising;
a housing; and
a control element comprising a thumbwheel with an exterior surface having a plurality of protrusions located on the exterior surface; and
a delivery catheter extending from the handle assembly comprising;
an outer sheath slidably controlled by the control element; and
an inner shaft slidably controlled by the control element, the inner shaft having a valve retainer;
a track having an exterior surface and a plurality of protrusions located on at least a portion of the exterior surface;
an outer sheath carrier connected to the track and the outer sheath;
an inner shaft carrier, having an exterior surface and a plurality of protrusions located on at least a portion of the exterior surface, connected to the inner shaft; and
a secondary gear having an exterior surface and a plurality of protrusions located on the exterior surface, wherein the protrusions on the thumbwheel directly interface with the protrusions on the track, the protrusions on the track directly interface with the protrusions on the secondary gear, and the protrusions on the secondary gear also directly interface with the protrusions on the inner shaft carrier.

Abstract
The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions.

21. A method of delivering a prosthetic heart valve with a prosthesis delivery system, the prosthesis delivery system comprising:
- a handle assembly comprising;
a housing; and
a control element; and
a delivery catheter extending from the handle assembly comprising;
an outer sheath slidably controlled by the control element; and
an inner shaft slidably controlled by the control element, the inner shaft having a valve retainer;
the method comprising;
inserting the delivery catheter into a body lumen;
advancing the delivery catheter within the body lumen to a deployment location;
activating the control element to simultaneously retract the outer sheath proximally and advance the inner shaft distally, and wherein the handle assembly further comprises;
a thumbwheel having an exterior surface and a plurality of protrusions located on the exterior surface;
a track having an exterior surface and a plurality of protrusions located on at least a portion of the exterior surface;
an outer sheath carrier connected to the track and the outer sheath;
an inner shaft carrier, having an exterior surface and a plurality of protrusions located on at least a portion of the exterior surface, connected to the inner shaft; and
a secondary gear having an exterior surface and a plurality of protrusions located on the exterior surface;
wherein the protrusions on the thumbwheel directly interface with the protrusions on the track, the protrusions on the track directly interface with the protrusions on the secondary gear, and the protrusions on the secondary gear also directly interface with the protrusions on the inner shaft carrier, and wherein activating the control element comprises rotating the thumbwheel, wherein rotating the thumbwheel causes the track and the outer sheath to move in a first direction, wherein movement of the track in the first direction causes the secondary gear to rotate, and wherein rotation of the secondary gear causes the inner shaft carrier and the inner shaft to move in a second direction. - View Dependent Claims (22, 23, 24)
