Appl. No.:

10/399209
Inventors:

Richard C. Ewers - Fullerton CA, US
John R. Brustad - Dana Point CA, US
Edward D. Pingleton - Laguna Niguel CA, US
Nabil Hilal - Laguna Niguel CA, US
Payam Adlparvar - Lake Forest CA, US

Charles C. Hart - Summerville SC, US
Robert R. Bowes - Aliso Viejo CA, US
Assignee:

Applied Medical Resources Corporation - Rancho Santa Margarita CA
International Classification:

A61B017/02
US Classification:

600208
Abstract:

A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment elements at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force.

US Patent:

7005026, Feb 28, 2006
Filed:

Nov 15, 2002
Appl. No.:

10/298116
Inventors:

John R Brustad - Dana Point CA, US
Payam Adlparvar - Lake Forest CA, US
Wassim R. Aliahmad - Irvine CA, US
Canh T. Tran - Garden Grove CA, US
Nabil Hilal - Laguna Niguel CA, US
Boun Pravong - Corona CA, US
Raffi S. Pinedjian - Fountain Valley CA, US
Charles C Hart - Summerville SC, US
Assignee:

Applied Medical Resources Corporation - Rancho Santa Margarita CA
International Classification:

B65H 81/00
US Classification:

156175, 156169, 156173, 1563082, 1563096
Abstract:

A releasable mechanism such as a cap is adapted for use with an access sheath having an elongate tube and a handle structure disposed at a proximal end of the tube. The releasable mechanism is sized and configured to fit the handle structure, which is shaped like the bell of a horn, to further facilitate use with surgical instrumentation. The releasable mechanism may operate as a separate cap that snaps onto the handle structure to provide access pathways to the sheath. The releasable mechanism may also be disposed at a proximal end of a surgical instrument to be introduced into the access sheath such that it may be interlocked with the sheath. In a method of manufacturing a kink-resistant sheath, a wire is initially coated with a plastic material, the coated wire is then wrapped around a mandrel forming a plurality of windings, and the wound coated wire is heated until the plastic material melts and bonds the windings to form a wire-reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, a thermoset or any plastic material having hard and/or soft durometer. The wound coated wire may be heated by capturing the windings within a shrink tube or compressing the windings in a mold and heating the windings until the sheath is formed.

Assignee:

Applied Medical Resources Corporation - Rancho Santa Margarita CA
International Classification:

A61B 1/32
US Classification:

600208, 6041672
Abstract:

A surgical access device includes a single valve that forms a seal with a body wall and provides an access channel into a body cavity.

The valve can include a gel material and the access channel can include a protective sleeve to provide for wound protection during insertion and withdrawal of a sharp surgical instrument. The valve further comprises a cap ring which may be inserted or molded with the gel material. The protective sleeve may be bonded or molded around an inner diameter of the cap ring. The protective sleeve may be a single tubular member, or may comprise a plurality of axially extending sleeve members having a plurality of axial slits. The protective sleeve and the cap ring may comprise of the same or different materials. The surgical access device further comprises at least one support ring disposed circumferentially of the valve forming a hollow space, and a wound retractor operatively placed in the hollow space.

Abstract:

A surgical access device includes a single valve forming a seal with the body wall and providing an access channel into a body cavity. The valve has properties for creating a zero-seal in the absence of an instrument and an instrument seal with instruments. The valve can include a gel comprised of an elastomer and oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon. A method for making the surgical access device includes combining a gelling agent with oil, preferably in a molding process. A method for using the device includes creating an opening with the instrument. An organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity.
