Publication number: 20110112374Abstract: The invention relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the “doming” phenomenon produced by insufflation of a patient's abdomen is reduced.Type: ApplicationFiled: January 14, 2011Publication date: May 12, 2011Applicant: Applied Medical Resources CorporationInventors: John R. Brustad, Jeremy J. Albrecht, Nabil Hilal, Gary M. Johnson, Charles C. Hart

Patent number: 7913697Abstract: An incrementally adjustable wound retractor (100), having a first ring (102) with a diameter greater than the desired diameter of the wound incision. A second ring (104), having an annular axis and a diameter greater than the desired diameter of the wound incision. A flexible sleeve (106), disposed in a generally cylindrical form between the first and second rings (102, 104), the second ring may be rolled over itself and around the annular axis to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.Type: GrantFiled: January 25, 2010Date of Patent: March 29, 2011Assignee: Applied Medical Resources CorporationInventors: Eric Nguyen, Donald L. Gadberry, Gary M. Johnson, Charles C. Hart, John R. Brustad, Robert R. Bowes, Jeremy J. Albrecht, Ghassan Sakakine, Henry Kahle

Patent number: 7909760Abstract: An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop placed therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.Type: GrantFiled: October 12, 2006Date of Patent: March 22, 2011Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Publication number: 20110054260Abstract: A surgical access system comprises a wound retractor comprising an outer anchor, an inner anchor, and a flexible, tubular sheath extending therebetween. Embodiments of the outer anchor comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. The sheath comprises a plurality of fibers or strands that improve the abrasion and puncture resistance thereof. Consequently, the surgical access system is useful in procedures in which damage to the sheath is likely, for example, orthopedic hip replacement, and spinal procedures. In some embodiments, the sheath tapers from the outer ring to the inner ring.Type: ApplicationFiled: August 31, 2010Publication date: March 3, 2011Applicant: Applied Medical Resources CorporationInventors: Jeremy J.

Patent number: 7892172Abstract: A wound retractor for retracting a surgical incision includes an inner ring, an outer ring and a distensible sleeve coupled to the inner and outer rings. The outer ring includes at least a pair of circular tubes coupled to each other. At least one of the circular tubes includes a lumen and a split that forms open ends. A noncompliant tubular hoop having a split therein is positioned in the lumen. The tubular hoop is oriented with its open ends positioned away from the split of the circular tubes. A core is positioned in the lumen of the tubular hoop. The core has a first end and a second end and is oriented with the ends positioned away from the split in the tubular hoop. The circular tubes may be parallel or may form a helical pattern similar to a Mobius strip.Type: GrantFiled: April 27, 2010Date of Patent: February 22, 2011Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Publication number: 20100179479Abstract: A surgical access device or trocar defines an access channel for instruments extending from a proximal end to the distal end thereof. The trocar comprises a cannula and a seal assembly disposed at the proximal end of the cannula. The seal assembly comprises a first or zero seal, a second or instrument seal, and a trocar shield disposed proximally of the first seal and the second seal. The first seal seals the access channel in the absence of an instrument extending therethrough. The second seal seals the access channel in the presence of an instrument extending therethrough. The trocar shield protects the first seal and second seal from damage as an instrument is advanced through the access channel. The trocar shield comprises an open proximal end and a tapered distal end comprising a plurality of longitudinal pleats, converging in an opening.Type: ApplicationFiled: January 11, 2010Publication date: July 15, 2010Applicant: Applied Medical Resources Corporation, Inc.Inventors: Jeremy J.
