Abstract

A biopsy incision closure device comprises a base having a frame incorporated therein. Together, the base and frame define an opening for performing a biopsy incision when the device is placed over a tissue surface. The base is typically composed of an elastomeric material and the frame comprises resilient inelastic members which can be used to close the opening in a highly uniform manner with minimum distortion and stress introduced into the tissue edges being drawn together.

Claims

1-22. -22. (canceled)

23. A method for biopsying tissues, said method comprising:

adhering a base having an opening to a tissue surface, said base including a resilient frame which surrounds the opening;

excising tissue through the opening, leaving a cavity having opposed, laterally spaced-apart edges in the tissue; and

closing the frames to apply a generally uniform distribution of lateral closing force along opposite sides of the opening to evenly close the edges of the cavity.

24. A method as in claim 23, wherein the opening in the base is elliptical.

25. A method as in claim 23, further comprising axially compressing the resilient frame to open the base opening before adhering the base to tissue.

26. A method as in claim 23, wherein the base preferentially stretches in an axial direction to accommodate elongation of the cavity as the opposite sides are closed in a lateral direction.

27. A method as in claim 26, the base is inhibited from stretching in the lateral direction by reinforcing elements on the frame.

28. A method as in claim 23, wherein closing comprises advancing a ratchet from one side of the frame to a laterally opposite side of the frame.

29. A method as in claim 23, further comprising applying an outward force at each end of the frame to flatten tissue as the frame is closed.

30. A method as in claim 23, wherein the frame comprises a lip configured to raise an inner periphery of the base opening to evert the tissue as the frame is closed.
