Medical device delivery systems and methods
First Claim
1. A delivery system for deploying a medical device, comprising:
- a first attachment member configured to selectively couple to and radially constrain a first end portion of the medical device, wherein the first attachment member includes an outer surface defining a plurality of slots leading to a cavity, wherein each of the plurality of slots is configured to receive a respective one of a plurality of coupling members of the first end portion of the medical device, wherein the first attachment member is configured to rotate betweena first position wherein the plurality of coupling members are configured to be disposed in the cavity and the plurality of slots are radially misaligned with the coupling members such that the outer surface radially constrains the coupling members, anda second position wherein each of the plurality of slots is radially aligned with one of the plurality of coupling members such that each of the coupling members may expand radially outward from the cavity through a respective one of the plurality of slots; and
a second attachment member configured to selectively couple to and radially constrain a second end portion of the medical device,wherein the first attachment member is configured to move relative to the second attachment member such that the first attachment member applies a first tensile force to the first end portion of a medical device in a first direction and the second attachment member applies a second tensile force to the second end portion of a medical device in a second direction substantially opposite from the first direction.

Abstract
A delivery system for deploying a medical device includes a first attachment member configured to selectively couple to and radially constrain a first end portion of the medical device. The delivery system also includes a second attachment member configured to selectively couple to and radially constrain a second end portion of the medical device. The first attachment member is configured to move relative to the second attachment member such that the first attachment member applies a first tensile force to the first end portion of a medical device in a first direction and the second attachment member applies a second tensile force to the second end portion of a medical device in a second direction substantially opposite from the first direction.

7. A system for replacing a native heart valve of a patient, comprising:
-
a prosthetic heart valve comprising a frame and a valve assembly coupled to the frame, the prosthetic heart valve comprising a first end portion, an intermediate portion, and a second end portion, wherein the first end portion comprises a plurality of first coupling members; a delivery system for deploying the prosthetic heart valve, the delivery system comprising; a first attachment member configured to selectively couple to and radially constrain the first end portion of the prosthetic heart valve, wherein the first attachment member includes a first outer surface defining a plurality of first slots leading to a first cavity, wherein each of the plurality of first slots is configured to receive a respective one of the plurality of first coupling members; and a second attachment member configured to selectively couple to and radially constrain the second end portion of the prosthetic heart valve, wherein the first attachment member is configured to move relative to the second attachment member such that the first attachment member applies a first tensile force to the first end portion of the prosthetic heart valve in a first direction and the second attachment member applies a second tensile force to the second end portion of the prosthetic heart valve in a second direction substantially opposite from the first direction, and wherein the first attachment member is configured to rotate between a first position wherein the first coupling members are disposed in the first cavity and the plurality of first slots are misaligned with the respective first coupling members such that the first outer surface radially constrains the first coupling members, and a second position wherein each of the plurality of first slots is radially aligned with one of the plurality of first coupling members such that each of the first coupling members may expand radially outward from the first cavity through a respective first slot. - View Dependent Claims (8, 9, 10)
