Benefits of technology

The present invention provides a biopsy closure device that can evenly distribute closure forces along the edges of a tissue cavity, reducing point-load forces and promoting faster and more uniform healing with minimal scarring. The device has a base made of a soft elastic material that can elongate in at least one direction and an hinge that applies an outward force to the tissue to flatten it at each end of the incision. Reinforcement members prevent unwanted tissue inversion effects and eversion lip promotes tissue eversion. The technical effects of the invention are improved healing and reduced scarring.

Problems solved by technology

While the legs will be biased to closing, usually the closure force is not sufficient to close the tissue after biopsy, and a further latching or other closure device will be needed to close the tissue opening, as described below.

Embodiment Construction

[0048]Referring to FIGS. 1A through 1D, a biopsy incision closure device 10 comprises a base 12 having an integrated or embedded frame 14, typically formed by overmolding a soft polymeric base material over a preformed metal or hard plastic frame. The frame 14 is resilient and, when free from biasing forces, assumes the elliptical or oval configuration seen in FIG. 1A. The frame 14 has living hinges 18 at each end (only one of which is visible in the broken-away section of the base) which allow the base to be closed by applying laterally inward forces to the frame, as shown in FIGS. 1C and 1D. Laterally inward forces may be provided by any one of a variety of external closure devices which could be simple tapes, patches, sutures, or the like. Closure devices could be more complex, including zippers, clips, and other structures as taught in copending PCT Application PCT / US2010 / 00430, the full disclosure of which has been previously incorporated herein by reference. Regardless of the ...

Abstract

A biopsy incision closure device includes 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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation U.S. Patent Application No. 13 / 096,602, filed Apr. 28, 2011, which claims the benefit of the following provisional applications: Provisional Application No. 61 / 343,916, filed on May 3, 2010; Provisional Application No. 61 / 397,604, filed on Jun. 14, 2010; and Provisional Application No. 61 / 462,329, filed on Feb. 1, 2011, the full disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to medical devices and methods. More particularly, the present invention relates to a device and method for closing a wound resulting from tissue biopsy.[0004]Excisional biopsy typically removes an elliptical section of tissue, usually containing the full dermis and in some cases the subcutaneous fatty layer as well. Such biopsies typically leave an elliptical opening in the skin that requires closing. Such elliptical bi...
