Publication number: 20230225729Abstract: A surgical stapling device includes tool assembly having an anvil and a cartridge assembly. The cartridge assembly includes a channel member that defines a cavity, a staple cartridge supported within the cavity of the channel member, and a biasing member. The staple cartridge supports staples, each having a back span and a pair of legs depending from the back span. The biasing member is positioned within the channel member and is deformable to allow the cartridge body to move vertically within the cavity of the channel member. The anvil incudes staple deforming pockets that are configured to deform the legs of the staples from a position within the same plane as the back span to positions laterally offset from the back span.Type: ApplicationFiled: March 23, 2023Publication date: July 20, 2023Applicant: Covidien LPInventors: John W. Beardsley, Stanislaw Z. Marczyk

Publication number: 20220168007Abstract: In some examples, a tool for, e.g., creating a sub-sternal tunnel in a patient or other use, is described. The tool may include a handle and a tunneling shaft coupled to the handle. The tunneling shaft extends from a proximal end to a distal end, and at least a portion of the tunneling shaft extends in a curved orientation between the first end to the distal end. The distal end of the tunneling shaft includes a cutting tool having a sharp edge. The cutting tool is moveable from a recessed position in which the sharp edge of the cutting tool is recessed into the distal end of the tunneling shaft to a deployed position in which the sharp edge of the cutting tool extends beyond the distal end of the tunneling shaft in the deployed position, e.g., to cut pericardium, scar tissue, and/or connective tissue with the sharp edge.Type: ApplicationFiled: December 7, 2021Publication date: June 2, 2022Inventors: Garrett P. Ebersole, Kyle R. Marquard, Krishnakumar Somasundaram, Stanislaw Z. Marczyk, Linnea R. Lentz, Olesea Diaz-Chiosa, Christopher Switalski

Publication number: 20210259684Abstract: A surgical stapler deploys staples made of selectively degradable materials. Tissue resected with a stapler of the present disclosure, including staples made of the selectively degradable materials, may be subjected to treatment in the lab to degrade those materials forming the staples. In this way, a pathologist or similar hospital personnel may rapidly degrade the staples, thereby permitting testing of the entire resected tissue sample for the presence of disease.Type: ApplicationFiled: February 4, 2021Publication date: August 26, 2021Inventors: Gerald N. Hodgkinson, Stanislaw Z. Marczyk, Andrew M. Miesse, Robert H. Knapp

Publication number: 20210030489Abstract: A colpotomy system includes a surgical instrument having a cutting element and a receiver at a distal end thereof and a uterine instrument. The uterine instrument has a handle operably coupled to a shaft having a balloon at a distal end thereof, the shaft extending through a retaining member to access a surgical site, the retaining member including a plurality of transmitters for transmitting at least one signal. A distance between the cutting element of the surgical instrument and one end of the retaining member of the uterine instrument is calculated to determine whether the cutting element is within a predetermined operating zone.Type: ApplicationFiled: October 20, 2020Publication date: February 4, 2021Inventors: Stanislaw Z.

Patent number: 8062332Abstract: A surgical needle includes an elongated needle body defining a longitudinal y-axis along which the needle body extends and transverse x and z-axes. The needle body includes a central shaft portion, a first suture end portion for attachment to a suture and a second needled end portion for penetrating tissue. The needled end portion has three sides which intersect to define three cutting edges and terminate at a needle point. At least one side includes a pair of planar surface portions arranged in oblique relation to define a general concave appearance to the one side. The needled end portion further defines an enlarged transition portion adjacent the central shaft portion with at least an x-dimension greater than a corresponding x-dimension of the central shaft portion.Type: GrantFiled: July 14, 2003Date of Patent: November 22, 2011Assignee: Tyco Healthcare Group LPInventors: Scott Cunningham, Stanislaw Z.
