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. Albrecht, Matthew M. Becerra, John R. Brustad, Juan Lechuga, Donald L. Gadberry, Gary M. Johnson, Aries E. Gatus, Kennii Pravongviengkham

Publication number: 20140263540Abstract: Jaw assemblies for a surgical stapler are provided. The jaw assemblies comprise a first jaw having a first clamping surface and a plurality of staples disposed therein and second jaw assembly having a second clamping surface. The jaw assemblies can be actuated from a closed configuration in which the first clamping surface contacts or is adjacent to the second clamping surface to an open configuration in which the second jaw is pivoted away from the first jaw to a stapling position in which the second clamping surface is parallel to the first clamping surface and spaced apart from the first clamping surface. A pivoting link or sliding pivot joint can couple the second jaw to the first jaw to facilitate motion between the closed position, the open position, and the stapling position.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: Applied Medical Resources CorporationInventors: Jonathan Covach, Matthew M. Becerra, Gary M. Johnson

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

Patent number: 8308746Abstract: The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.Type: GrantFiled: April 14, 2008Date of Patent: November 13, 2012Assignee: Applied Medical Resources CorporationInventors: Boun Pravong, Kennii Pravongviengkham, Matthew M.
