Abstract
Embodiments of a leaflet clip device and method of reducing regurgitation through a native heart valve are disclosed. A leaflet clip device can include an elongated clipping member having a first end portion and a second end portion and a tensioning mechanism coupled to the clipping member. The leaflet clip device can further include one or more tensioning members disposed within a lumen of the clipping member, wherein the one or more tensioning members are operatively connected to the tensioning mechanism to transform the clipping member from a delivery configuration to an implantation configuration.
Claims22
A leaflet clip device, comprising:
- an elongated clipping member having a first end portion and a second end portion;
- a tensioning mechanism coupled to the clipping member;
- and
- one or more tensioning members disposed within a lumen of the clipping member, wherein the one or more tensioning members are operatively connected to the tensioning mechanism to transform the clipping member from a delivery configuration to an implantation configuration.
A leaflet clip device, comprising:
- a clipping member comprising a tubular body having a lumen and two leg portions, wherein the clipping member can be transformed between a substantially linear delivery configuration and an implantation configuration in which the leg portions are drawn toward each other to capture a pair of leaflets between the leg portions;
- and
- a tensioning mechanism configured to transform the clipping member from the delivery configuration to the implantation configuration.
A method of reducing regurgitation through a native heart valve, comprising:
- positioning a leaflet clip device adjacent the coaptation edges of two adjacent leaflets of the heart valve, wherein the leaflet clip device comprises a clipping member and first and second tensioning members disposed within a lumen of the clipping member, the first tensioning member fixed to a first end portion of the clipping member and the second tensioning member fixed to a second end portion of the clipping member;
- and
- applying tension to the tensioning members to transform the clipping member from a delivery configuration to an implantation configuration in which the coaptation edges of the leaflets are captured between two leg portions of the clipping member.
