Prosthetic heart valves, scaffolding structures, and systems and methods for implantation of same
First Claim
1. A medical apparatus, comprising an elongate delivery device configured to deliver a prosthetic heart valve, the delivery device comprising a gripper comprising a plurality of fingers, and a tubular member comprising an inner lumen and a plurality of longitudinal slots in the periphery of a distal portion thereof, the longitudinal slots being adapted to allow extension of the prosthetic heart valve therethroughwherein said gripper is slidably disposed within the inner lumen of said tubular member and said plurality of fingers have a first position within the interior of the distal end of the tubular member and a second position extending outward from the distal end of the tubular member, and wherein the plurality of fingers are fixedly coupled to the gripper such that the plurality of fingers remain in a fixed position with respect to each other.

1. A medical apparatus, comprising an elongate delivery device configured to deliver a prosthetic heart valve, the delivery device comprising a gripper comprising a plurality of fingers, and a tubular member comprising an inner lumen and a plurality of longitudinal slots in the periphery of a distal portion thereof, the longitudinal slots being adapted to allow extension of the prosthetic heart valve therethrough
wherein said gripper is slidably disposed within the inner lumen of said tubular member and said plurality of fingers have a first position within the interior of the distal end of the tubular member and a second position extending outward from the distal end of the tubular member, and wherein the plurality of fingers are fixedly coupled to the gripper such that the plurality of fingers remain in a fixed position with respect to each other.

19. The delivery device of claim I, wherein the tubular member comprises a plurality of elongate segments in the periphery of the distal portion, the elongate segments being spaced apart such that one of the plurality of longitudinal slots exists between each adjacent pair of elongate segments, the elongate segments extending parallel to a longitudinal axis of the tubular member.

20. A delivery device for a prosthetic heart valve, comprising:
-
a catheter having a proximal end, a distal end, and defining a longitudinal axis, the distal end of said catheter comprising a gripper having a plurality of rigid, elongate restraining members near its distal end, and an outer member having an inner lumen and a plurality of longitudinal slots in the periphery of a distal portion thereof, wherein said gripper is slidably disposed within the inner lumen of said outer member, wherein each restraining member extends generally parallel to the longitudinal axis of the catheter and has a proximal portion that is attached to the gripper and a distal portion that is not attached to the gripper, thereby defining a central region located internally of the plurality of restraining members and a longitudinal space between each adjacent pair of restraining members, and wherein the plurality of restraining members are fixedly coupled to the gripper such that the plurality of restraining members remain in a fixed position with respect to each other and wherein the plurality of restraining members are adapted to retain the prosthetic heart valve. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A delivery device for a prosthetic heart valve, comprising:
-
a gripper comprising a plurality of fingers fixedly coupled to the gripper such that the plurality of fingers remain in a fixed position with respect to each other, and a tubular member comprising an inner lumen and a plurality of elongate segments in the periphery of a distal portion thereof, the elongate segments being spaced apart such that a longitudinal slot exists between each adjacent pair of elongate segments, the elongate segments extending parallel to a longitudinal axis of the tubular member, wherein said gripper is slidably disposed within the inner lumen of said tubular member and said plurality of fingers are configured to retain a prosthetic heart valve such that the heart valve can be positioned within the inner lumen of the tubular member, the fingers being further configured to disengage from the heart valve to deploy the heart valve in a patient'"'"'s body.
