Sealing wound closure device

A wound closure device comprising a substantially annular pad member having opposed, substantially planar surfaces, and a central opening therethrough;

• a protective covering releasably secured to one planar surface of said pad member;
• an affixing means, secured to the surface opposite said one surface of the annular pad member for affixing the device to skin of a patient having a wound or ulceration such that the wound is positioned within said central opening,
• said affixing means comprises;
• an adhesive;
• and,
• a plurality of removable pins.

A wound closure device comprising a substantially annular pad member having opposed, substantially planar surfaces, and a central opening therethrough;

• a protective covering releasably secured to one planar surface of said pad member;
• said annular pad member being formed from resilient material, capable of being expanded to surround a wound whereby when said pad member is permitted to relax, its resilience acts to draw together the tissue surrounding the wound to assist in providing closure of the wound;
• an affixing means, secured to the surface opposite said one surface of the annular pad member for affixing the device to the skin of a patient having a wound or ulceration such that the wound is positioned within said central opening;
• and,
• a plurality of additional resilient pad members disposed radially inward from the inner perimeter of said annular pad member.

• planar surfaces, and a central opening therethtough;
• a protective covering releasably secured to one planar surface of said pad member;
• said annular pad member being formed resilient material, capable of being expanded to surround a wound whereby when said pad member is permitted to relax, its resilience acts to draw together the tissue surrounding the wound to assist in providing closure of the wound;
• an affixing means, secured to the surface opposite said one surface of the annular pad member for affixing the device to the skin of a patient having a wound or ulceration such that the wound is positioned within said central opening;
• expansion means for expanding said annular resilient pad member having handle means for manually operating said expansion means;
• said expansion means engaging said annular resilient pad member to provide radial expansion of said annular resilient pad member such that release of said handle means will enable radial contraction of said annular resilient pad member;
• said expansion means further comprises an upper control ring which, when moved toward said protective covering exerts expansion forces on said annular resilient pad.

In combination, a wound closure device with means for applying the wound closure device to a wound site, said wound closure device comprising:

• a substantially annular, resilient pad having a central opening therethrough;
• an overlying removable protective covering on said annular resilient pad;
• means for affixing the device to a wound site with the wound site surrounded by the central opening in said pad member;
• said applying means including releasable means for expanding said resilient pad member such that, upon release of the releasable means said resilient pad member contracts radially, thereby drawing together the tissues adjacent to the wound to assist in providing closure of the wound, and,
• said applying means further includes:
• a plurality of flanges disposed in spaced relation around around the periphery of said annular resilient pad, wherein said applying means includes arm means engaging said flanges for exerting radially outward acting force on said annular resilient pad and radial expansion thereof.

A circular wound closure and protective device comprising:

• (a) a circular elastic planar pad with a concentric hole forming an annulus;
• (b) said circular elastic planar pad having an adhesive coating on a front face thereof;
• (c) elastic material overlying and covering both a back face and the annulus of said circular elastic planar pad;
• (d) an expansion means including at least two radially aligned flanges protruding generally normal to the plane of the circular elastic planar pad, said flanges being attached to the outer perimeter of the circular elastic planar pad;
• (e) said flanges being adapted to receive a releasable controlling means for radially stretching the device before it is adhesively applied to skin surrounding a wound, so that when the releasable controlling means is released said device will elastically contract and act to close the wound.
