Patent number: 9241697Abstract: A retraction device for retracting an incision in a body wall includes a sheath that traverses through the incision from outside the body to a body cavity inside the body. The retraction device may include a first, distal retention ring, a second, proximal retention ring, a circumferential, tubular sheath that is coupled to the first and second retention rings, a plurality of tensioning straps, and a proximal lock ring, wherein each of the plurality of straps is coupled to the distal retention ring and extends proximally through the lumen of the sheath and the proximal retention ring. The lock ring is sized and configured to capture the straps between an inner surface of the proximal retention ring and an outer surface of the lock ring. The lock ring is adapted to be positioned within a lumen of the proximal retention ring with the straps exiting between the proximal retention ring and the lock ring.Type: GrantFiled: June 19, 2014Date of Patent: January 26, 2016Assignee: Applied Medical Resources CorporationInventors: Jeremy J Albrecht, Charles C Hart, Eric Nguyen, Haruyasu Yawata, Nabil Hilal

Publication number: 20150367088Abstract: An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed. The instrument comprises a shaft having an insufflation channel extending between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end. A tip is at the distal end and a vent hole is formed in the tip being in connection with the insufflation channel and adapted to expel fluid under pressure to insufflate the abdominal region. The tip is formed of a transparent material to facilitate visualization of the abdominal wall and region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel.Type: ApplicationFiled: September 1, 2015Publication date: December 24, 2015Inventors: Jeremy J.

The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.Type: ApplicationFiled: January 26, 2015Publication date: May 21, 2015Inventors: Jeremy J.

Patent number: 9017254Abstract: The application 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: GrantFiled: January 7, 2014Date of Patent: April 28, 2015Assignee: Applied Medical Resources CorporationInventors: John R.

Patent number: 8961410Abstract: A surgical access device has a surgical retractor having a noncompliant outer ring with an annular axis, an inner ring, and a sleeve coupling the outer ring to the inner ring. The noncompliant outer ring is adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal an opening in a biological body wall. The access device may include a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor. The outer ring of the surgical retractor has a cross-sectional shape that prohibits the lid from being partially or incorrectly coupled to the outer ring of the surgical retractor.Type: GrantFiled: January 6, 2012Date of Patent: February 24, 2015Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Patent number: 8894571Abstract: Embodiments of a surgical access system useful for single or limited port procedures comprise a trocar comprising a fixation cannula, a retractor, and a gel cap removably coupled to the retractor. The gel cap comprises a gel pad that acts as an artificial body wall, through which instruments may be inserted into a body cavity, either directly or through one or more trocars. The fixation cannula comprises a retainer and a bolster, which together, capture the artificial body wall therebetween, thereby fixing the trocar thereto. The gel pad permits flexible instrument placement, as well as translational and angular degrees of freedom for the instruments while maintaining a gas tight seal.Type: GrantFiled: April 1, 2014Date of Patent: November 25, 2014Assignee: Applied Medical Resources CorporationInventors: Jeremy J.
