Patent number: 9326776Abstract: A surgical clip applier is provided having a cartridge carrying multiple surgical clips with a manual graspable actuator configured to sequentially deliver clips to the jaws of the clip applier. Both the cartridge and the jaws are connectable to a scissors-like handle assembly arranged to translate motion from finger loops to the jaws to open and close the jaws and thus close or crimp a delivered clip between the jaws.Type: GrantFiled: September 28, 2006Date of Patent: May 3, 2016Assignee: Applied Medical Resources CorporationInventors: Donald L.

Publication number: 20160051259Abstract: A surgical stapler is provided. The stapler employs circumferential channels through which staples are deployed along an arc pathway against an anvil surface. The curved channels allow staples with relatively longer legs to be used in the stapler having a smaller diameter at the jaws. Also, by utilizing a curved path, a much larger staple can be placed in the same diameter device. Specialized curved staples for use with the stapler of the present invention are also provided. To further enable the benefits of the stapler with circumferential channels and method of staple deployment, novel jaw reinforcement structures are provided in the present invention. The jaw reinforcement structures are located towards the center or bladeline of the device instead of around the circumference as in conventional staplers, thereby clearing the outer area near the circumference of the device to provide room for longer staples and staple firing components.Type: ApplicationFiled: November 5, 2015Publication date: February 25, 2016Inventors: Timothy M. Hopkins, Atal C. Patel, Donald L. Gadberry, Matthew M. Becerra

Patent number: 9259238Abstract: A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. 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: GrantFiled: January 26, 2015Date of Patent: February 16, 2016Assignee: 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.

Publication number: 20140296778Abstract: A steerable kink resistant access device is provided having an elongated body and a steerable portion; methods for manufacturing the kink resistant device are also provided. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.Type: ApplicationFiled: January 27, 2014Publication date: October 2, 2014Applicant: Applied Medical Resources CorporationInventors: Charles C.

Publication number: 20140263570Abstract: A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: Applied Medical Resources CorporationInventors: Timothy Hopkins, Donald L. Gadberry, Matthew M. Becerra, Babak Jasemian, Gary M. Johnson, Steven E. Decker

Publication number: 20140207115Abstract: The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure.Type: ApplicationFiled: March 24, 2014Publication date: July 24, 2014Applicant: Applied Medical Resources CorporationInventors: John R.
