Abstract
Described embodiments are directed toward centrally-opening leaflet prosthetic valve devices having a leaflet frame and a mechanically coupled leaflet. The described leaflet frames have projections that are configured to couple with a leaflet attachment region of a leaflet. Some embodiments include a leaflet retention feature that engages the leaflet frame projections and operates to secure the leaflet to the leaflet frame. Methods of making and using such prosthetic valve devices are also described.
Claims30
A prosthetic valve comprising:
- a plurality of leaflets including a first leaflet and a second leaflet, each leaflet having a leaflet attachment region and each leaflet having a free edge;
- and
- a frame including a commissure post that comprises:
- a first tine including a first interior edge and a first exterior edge opposite the first interior edge, the first tine including a first projection extending from the first exterior edge of the first tine;
- and a second tine including a second interior edge and a second exterior edge opposite the second interior edge, the second tine including a second projection extending from the second exterior edge of the second tine;
- a spine positioned between the first and second tines such that the interior edges of the first and second tines face the spine, the spine being positioned between at least a portion of the first and second leaflets such that a gap is defined between the leaflet free edges of the first and second leaflets adjacent the commissure post;
- and
- a first slot and a second slot, the first slot being defined between the first tine and the spine, and the second slot being defined between the second tine and the spine,
- wherein the leaflet attachment region of the first leaflet extends through the first slot and wraps around the first tine and engages the first projection, and wherein a first portion of the leaflet attachment region of the second leaflet extends through the second slot and wraps around a portion of the second tine and engages the second projection.

- a plurality of leaflets including a first leaflet and a second leaflet, each leaflet having a leaflet attachment region and each leaflet having a free edge;
- and
- a frame including:
- a spine positioned between at least a portion of the first and second leaflets such that a gap is formed between the leaflet free edges of the first and second leaflets adjacent the spine;

- and
- a plurality of projections extending from the first and second tines, the plurality of projections includes a first projection extending from the first tine and a second projection extending from the second tine,
- wherein the leaflet attachment region of the first leaflet extends through the first slot and wraps around the first tine and engages the first projection extending from the first tine, and wherein the leaflet attachment region of the second leaflet extends through the second slot and wraps around the second tine and engages the second projection extending from the second tine.

A method of manufacturing a heart valve, comprising:
- providing a plurality of leaflets including a first leaflet and a second leaflet, each leaflet having a leaflet attachment region and each leaflet having a free edge;
- providing a frame including a commissure post that comprises:
- a first tine including a first interior edge and a first exterior edge opposite the first interior edge, the first time including a first projection extending from the first exterior edge of the first tine;
- and a second tine including a second interior edge and a second exterior edge opposite the second interior edge, the second time including a second projection extending from the second exterior edge of the second tine;
- a spine positioned between the first and second tines such that the interior edges of the first and second tines face the spine;
- and
- a plurality of slots including a first slot and a second slot, the first slot being defined between the first tine and the spine, and the second slot being defined between the second tine and the spine,
- coupling the leaflet attachment region of the first leaflet to the frame by extending the leaflet attachment region of the first leaflet through the first slot and wrapping the leaflet attachment region of the first leaflet around the first tine such that the leaflet attachment region of the first leaflet engages the first projection;
- and
- coupling the leaflet attachment region of the second leaflet to the frame by extending the leaflet attachment region of the second leaflet through the second slot and wrapping the leaflet attachment region of the second leaflet around the second tine such that the leaflet attachment region of the second leaflet engages the second projection with the spine positioned between at least a portion of the first and second leaflets such that a gap is formed between the leaflet free edges of the first and second leaflets adjacent the spine.
