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.
Claims18
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;
- 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.
A method of deploying a medical device, comprising:
- coupling a first end portion of the medical device to a first attachment member of a delivery system;
- coupling a second end portion of the medical device to a second attachment member of the delivery system;
- moving the first attachment member relative to the second attachment member to increase a distance between the first attachment member and the second attachment member, wherein the moving the first attachment member relative to the second attachment member causes the first attachment member to apply a first tensile force to the first end portion of the medical device in a first direction and the second attachment member to apply a second tensile force to the second end portion of the medical valve in a second direction substantially opposite from the first direction, whereby the medical device is compressed to a first compressed diameter.
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 frame comprising a first end portion, an intermediate portion, and a first portion;
- 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 a first end portion of the prosthetic heart valve;
- and
- a second attachment member configured to selectively couple to and radially constrain a 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.
