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 tissue, the method comprising:

deploying a first attachment device through tissue at a first location and through a first complementary attachment device;

attaching the first attachment device to the first complementary attachment device; and

deploying a second attachment device through the tissue at a second location and through a second complementary attachment device;

wherein the first and second complementary attachment devices are discretely formed and are attached to an annular wall of a gasket body at circumferentially spaced apart locations, such that the steps of deploying the first and second attachment devices results in the first and second attachment devices being associated with differing locations of the annular wall;

and further wherein each of the first and second complementary attachment devices is adapted to fixedly couple to the corresponding attachment device.

2. The method of claim 1, wherein the step of attaching the first attachment device to the first complementary attachment device comprises crushing the first complementary attachment device.

3. The method of claim 1, wherein the step of attaching the first attachment device to the first complementary attachment device comprises inserting a space-occupying element into the first complementary attachment device.

4. 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 first 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 such that the step of deploying the first attachment device includes locating the first attachment device outside of the gasket body.

5. 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 first 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 such that the step of deploying the first attachment device includes locating the first attachment device within the inner gasket radius.

6. A method of attaching a gasket body to tissue, the method comprising:

deploying a first attachment device through tissue at a first location and through a first complementary attachment device;

deploying a second attachment device through the tissue at a second location and through a second complementary attachment device;

wherein the first and second complementary attachment devices are discretely formed and are attached to an annular wall of the gasket body at circumferentially spaced apart locations, such that the steps of deploying the first and second attachment devices results in the first and second attachment devices being associated with differing locations of the annular wall;

and further wherein each of the first and second attachment devices is fixedly coupled to the corresponding complementary attachment device.

7. The method of claim 6, wherein the first attachment device is fixedly coupled to the first complementary attachment device by crushing the first complementary attachment device.

8. The method of claim 6, wherein the first attachment device is fixedly coupled to the first complementary attachment device by inserting a space-occupying element into the first complementary attachment device.

9. The method of claim 6, 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 first 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 such that the step of deploying the first attachment device includes locating the first attachment device outside of the gasket body.

10. The method of claim 6, 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 first 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 such that the step of deploying the first attachment device includes locating the first attachment device within the inner gasket radius.

11. A method of attaching a gasket body to tissue, wherein the gasket body comprises a gasket wall, the method comprising:

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

attaching the first attachment device to the tissue,

attaching the first attachment device to the first receptacle,

deploying a second attachment device through a second receptacle attached to the gasket body, the second receptacle being discrete from the first receptacle and attached to the gasket body at a location circumferentially spaced from the first receptacle;

attaching the second attachment device to the tissue, and

attaching the second attachment device to the second receptacle.

12. A method of attaching a gasket body to tissue, the method comprising:

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

attaching the first attachment device to the tissue,

attaching the first attachment device to the first complementary attachment device,

deploying a second attachment device through a second complementary attachment device that is discrete from the first complementary attachment device and is attached to the gasket body at a location circumferentially spaced from the first complementary attachment device,

attaching the second attachment device to the tissue, and

attaching the second attachment device to the second complementary attachment device,

wherein the first and second complementary attachment devices are located on an outer radial side of the gasket body.
