Abstract

Devices for fixturing a prosthesis to a first mass and methods of making and using the same are disclosed. Complementary fixturing devices and methods of making and using the same are also disclosed. The devices can be used to attach a heart valve gasket body to a biological annulus.

Claims

1. A method of attaching a gasket body to a first mass, the method comprising:

deploying an attachment device through a first mass and a complementary attachment device, wherein the complementary attachment device is attached to the gasket body, such that the complementary attachment device is adapted to fixedly couple to the attachment device.

2. The method of claim 1, further comprising attaching the attachment device to the first mass.

3. The method of claim 1, further comprising attaching the attachment device to the complementary attachment device.

4. The method of claim 3, wherein attaching the attachment device to the complementary attachment device comprises crushing the complementary attachment device.

5. The method of claim 3, wherein attaching the attachment device to the complementary attachment device comprises inserting a space-occupying element into the complementary attachment device.

6. The method of claim 1, wherein the gasket body comprises a longitudinal axis central to the gasket body, the gasket body further comprises an inner gasket radius, and an outer gasket radius,

and wherein the complementary attachment device comprises an inner attachment radius and an outer attachment radius,

and wherein the inner gasket radius, the outer gasket radius, the inner attachment radius and the outer attachment radius are measured from the longitudinal axis,

and wherein the outer attachment radius is greater than the outer gasket radius.

7. The method of claim 1, wherein the gasket body comprises a longitudinal axis central to the gasket body, the gasket body further comprises an inner gasket radius, and an outer gasket radius,

and wherein the complementary attachment device comprises an inner attachment radius and an outer attachment radius,

and wherein the inner gasket radius, the outer gasket radius, the inner attachment radius and the outer attachment radius are measured from the longitudinal axis,

and wherein the inner attachment radius is less than the inner gasket radius.

8. A method of attaching a gasket body to a first mass, the method comprising:

deploying an attachment device through a first mass and a complementary attachment device, wherein the complementary attachment device is attached to the gasket body, such that the attachment device is fixedly coupled to the complementary attachment device.

9. The method of claim 8, further comprising attaching the attachment device to the first mass.

10. The method of claim 8, further comprising attaching the attachment device to the complementary attachment device.

11. The method of claim 10, wherein attaching the attachment device to the complementary attachment device comprises crushing the complementary attachment device.

12. The method of claim 10, wherein attaching the attachment device to the complementary attachment device comprises inserting a space-occupying element into the complementary attachment device.

13. The method of claim 10, wherein the gasket body comprises a longitudinal axis central to the gasket body, the gasket body further comprises an inner gasket radius, and an outer gasket radius,

and wherein the complementary attachment device comprises an inner attachment radius and an outer attachment radius,

and wherein the inner gasket radius, the outer gasket radius, the inner attachment radius and the outer attachment radius are measured from the longitudinal axis,

and wherein the outer attachment radius is greater than the outer gasket radius.

14. The method of claim 10, wherein the gasket body comprises a longitudinal axis central to the gasket body, the gasket body further comprises an inner gasket radius, and an outer gasket radius,

and wherein the complementary attachment device comprises an inner attachment radius and an outer attachment radius,

and wherein the inner gasket radius, the outer gasket radius, the inner attachment radius and the outer attachment radius are measured from the longitudinal axis,

and wherein the inner attachment radius is less than the inner gasket radius.

15. A method of attaching a gasket body to a first mass, wherein the gasket body comprises a gasket wall, the method comprising:

deploying an attachment device through a discrete receptacle attached to the gasket body,

attaching the attachment device to the first mass, and

attaching the attachment device to the discrete receptacle.

16. A method of attaching a gasket body to a first mass, the method comprising:

deploying an attachment device through a complementary attachment device attached to the gasket body,

attaching the attachment device to the first mass, and

attaching the attachment device to the complementary attachment device,

wherein the complementary attachment device is located on an outer radial side of the gasket body.
