First Claim
Patent Images
1. A method of exposing perforating veins of the body to endoscopic instruments, said perforating veins extending from a superficial location beneath the layer of skin and fat to a deep location within tissue underlying the skin and fat and fascia, said method comprising;
- making a small incision through the skin, fat and fascia near the expected location of the perforating veins;
inserting a balloon dissector into the small incision;
inserting the balloon dissector under the skin, fat and fascia to the area in which the perforating veins are expected to be found;
inflating the balloon dissector;
said steps of inserting and inflating the balloon dissector being used to dissect the skin, fat and fascia layer from the tissue underlying the skin, fat and fascia, thereby exposing the perforating veins to allow surgical procedures on the perforating veins using the endoscopic instruments.

Abstract
A method of exposing, ligating and dividing perforating veins endoscopically using balloon dissectors to gain access to the perforating veins, thereby avoiding large incisions required in the Linton procedure and similar open surgical procedures.

2. A method of exposing perforating veins of the body, said perforating veins extending from a superficial location beneath the layer of skin, fat and fascia to a deep location within tissue underlying the skin, fat and fascia, said method comprising;
-
making a small incision through the skin, fat and fascia near the expected location of the perforating veins; inserting a balloon dissector into the small incision; inserting the balloon dissector under the skin, fat and fascia to the area in which the perforating veins are expected to be found; inflating the balloon dissector; said step of inserting and inflating the balloon dissector being used to dissect the skin, fat and fascia layer from the body tissue underlying the skin, fat and fascia, thereby creating a dissected area and exposing the perforating veins to allow surgical procedures on the perforating veins; inserting endoscopic surgical instruments under the skin, fat and fascia layer, and using said endoscopic surgical instruments to ligate and divide the exposed perforating veins.

3. A method of ligating and dividing incompetent perforating veins in a human patient suffering from venous insufficiency in the legs, said venous insufficiency evidenced by deteriorated skin around the ankle including discolored skin and skin ulcers, wherein said leg includes superficial veins and deep veins and incompetent perforating veins communicating between said the superficial veins and deep veins, and includes an area of healthy skin remote from the incompetent perforating veins and the deteriorated skin around the ankle, the said method comprising:
-
making a small incision in the area of healthy skin remote from the deteriorated skin; inserting a balloon dissector into the small incision, and pushing the balloon dissector under the skin and toward the area of the incompetent perforating veins, thereby dissecting the skin, fat, and deep fascia of the leg from underlying body tissue and creating a dissected space in the area of the perforating veins; inflating the balloon dissector to enlarge the dissected space so that the dissected space is large enough to accommodate the insertion of endoscopic instruments; inserting endoscopic instruments into the dissected space and manipulating the instruments to ligate and divide the incompetent perforating veins. - View Dependent Claims (6, 7)

4. A method of performing a Linton procedure endoscopically, said method comprising:
-
making a small incision near the top of the Linton line, said incision extending through the layer of skin, fat, and deep fascia covering the calf; inserting a balloon dissector between the layer of skin, fat, and deep fascia of the calf and the muscle underlying the skin, fat, and deep fascia; dissecting the skin, fat, and deep fascia layer away from the muscle by inflating the balloon dissector and forcing the balloon dissector between the skin, fat, and deep fascia layer and the muscle in the proximity of the Linton line; and inserting an endoscopic instrument and manipulating the instrument to ligate and divide a perforating vein. - View Dependent Claims (5)

17. A method of treating perforating veins of the body, said perforating veins extending from a superficial location beneath the subcutaneous layers of skin and fat to a deep location underlying the skin, fat and fascia, said method comprising the following steps:
-
making an incision through the skin, fat and fascia at a location near the perforating veins to be treated; inserting a balloon dissector through the incision and advancing the balloon under the skin, fat and fascia to a first area in which perforating veins are located; inflating said balloon dissector, thereby exposing a first perforating vein; inserting endoscopic surgical instruments under the skin, fat, and fascia layer and using said endoscopic surgical instruments to divide and ligate the first perforating vein; deflating said balloon dissector; advancing said balloon dissector to another area in which perforating veins are located; inflating said balloon dissector, thereby exposing a second perforating vein; inserting endoscopic surgical instruments under the skin, fat, and fascia layer and using said endoscopic surgical instruments to divide and ligate the second perforating vein. - View Dependent Claims (18)
