Abstract

The present invention provides tissue capture devices configured to hold tissue in a distorted configuration. The devices may hold precaptured tissue in a distorted configuration or it may change their shape to cause the tissue to become deformed. Some embodiments of the device alter the configuration in areas that remain external to the tissue, while other embodiments change their configuration in areas that are implanted in the tissue. Other embodiments may be mechanically altered to hold the tissue in a distorted shape.

Claims

1. A tissue capturing element comprising:

an internal tissue contacting portion,

an external tissue portion, and

a tissue contacting anchor for maintaining the element in position relative to the tissue.

2. A tissue capturing element as defined in claim 1 further comprising a first configuration and a second configuration.

3. A tissue capturing element as defined in claim 2 wherein the interior tissue portion is configured to undergo a shape change that distinguishes the second configuration from the first configuration.

4. A tissue capturing element as defined in claim 2 wherein the exterior tissue portion is configured to undergo a shape change that distinguishes the second configuration from the first configuration.

5. A tissue capturing element as defined in claim 2 wherein the tissue anchor is configured to undergo a shape change that distinguishes a second configuration from the first configuration.

6. A method of capturing tissue in a distorted form comprising:

providing a tissue capturing element having an exterior tissue portion, an interior tissue portion and a tissue anchor portion;

inserting the tissue capturing element so that the interior tissue portion is contained within the subject tissue;

deforming the interior tissue portion of the device to engage the tissue.

7. A method of capturing tissue in a distorted form comprising:

providing a tissue capturing element having an exterior tissue portion, an interior tissue portion and a tissue anchor portion;

inserting the tissue capturing element so that the interior tissue portion is contained within the subject tissue;

deforming the exterior tissue portion to engage the tissue.

8. A method of capturing tissue in a distorted form comprising:

providing a tissue capturing element having an exterior tissue portion, an interior tissue portion and a tissue anchor portion;

inserting the tissue capturing element so that the interior tissue portion is contained within the subject tissue;

deforming the tissue anchor portion in order to engage the tissue.

9. A tissue capturing element comprising:

at least one tissue engaging portion;

at least one distortion portion for becoming distorted to hold tissue in a distorted shape; and

at least one securement mechanism for retaining the element in its tissue distorting form.
