Patent number: 11957343Abstract: Surgical fasteners for use with articulating surgical instruments are disclosed. In one embodiment, a surgical fastener may include a head, a shaft extending distally from the head, and a through bore extending through the shaft from a proximal surface of the head to a distal end of the shaft. A fastener carrier of a surgical instrument may be slidably received in the through bore, and the through bore may be sized and shaped to have two or fewer contact points with the fastener carrier when the fastener carrier is in a fully articulated configuration. In another embodiment, a fastener may include a head, a shaft extending distally from the head and including a distal tip, a sloped surface sloping toward the distal tip, and a through bore passing through the head, shaft, and sloped surface. The sloped surface may terminate at two shoulders located on opposing sides of the through bore.Type: GrantFiled: February 12, 2021Date of Patent: April 16, 2024Assignee: C.R.

Patent number: 11944289Abstract: Articulating surgical instruments are disclosed. In one embodiment, a surgical instrument may include an elongated shaft assembly including an articulable portion moveable between a non-articulated configuration and an articulated configuration. First and second articulating shafts of the elongated shaft assembly may be coaxially arranged and axially fixed at an attachment point located distally from the articulable portion. Proximal portions of the first and second articulating shafts may be displaceable in opposing directions to articulate the articulable portion from the non-articulated configuration to the articulated configuration. In another embodiment, an articulation control may be movable from a first position to a second position to move an articulation lock from a locked configuration to an unlocked configuration to selectively permit articulation of a surgical instrument. The articulation lock also may be movable from the second position to a third position to articulate the surgical instrument.Type: GrantFiled: August 12, 2021Date of Patent: April 2, 2024Assignee: C.R.

Publication number: 20230107636Abstract: A deployment device for positioning a soft tissue repair prosthesis includes a self-expanding support body releasably attachable to the prosthesis. The support body may be removably insertable into a pocket of the prosthesis. A handle coupled to the support body facilitates positioning the patch and/or removal of the support body from the pocket. The support body may substantially occupy the pocket in an expanded configuration. The handle may be arranged to direct a pulling force to the outer peripheral edge of the support body and/or cause a portion thereof to be pulled downward and below the body during withdrawal of the deployment device from the prosthesis. The support body may include support segments pivotally coupled together and foldable to collapse the support body for insertion into and removal from the pocket. One or more resilient support members may be provided for collapsing and expanding the support body and the prosthesis.Type: ApplicationFiled: September 7, 2022Publication date: April 6, 2023Applicant: C.

Publication number: 20220409356Abstract: An implantable prosthesis for repairing a defect in a muscle or tissue wall. The prosthesis comprises a body of biologically compatible prosthetic material having a preformed three-dimensional contoured shape that independently assumes a three-dimensional curved shape configured to conform to the muscle or tissue wall. The body may be formed of a mesh fabric employing a knit construction. The body may be configured with one or more mechanical characteristics, individually or in any combination, having defined properties which may enhance the ability of the prosthesis to be handled in a surgical, robotic environment while meeting the performance and physical characteristics for soft tissue repair and reconstruction. One or more visual indicia may be provided to facilitate positioning and/or placement of the prosthesis at the muscle or tissue wall.Type: ApplicationFiled: July 11, 2022Publication date: December 29, 2022Applicant: Davol Inc.Inventors: Augustus Felix, Talia D’Ambruoso, Cuixiang Qu Spinney, Korel Cudmore
