  • Patent number: 12029416
    Abstract: Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft including a reciprocating driveshaft disposed within the elongated shaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft for displacing one or more fasteners within the elongated shaft towards a distal fastener deployment position. In some embodiments, the surgical instrument may include a magnetic preload lock-out to place the follower in a zero-load state in which the follower does not apply a preload to the fasteners.

  • Publication number: 20240215979
    Abstract: Devices and methods for closure of apertures in tissue (e.g., defects in fascial tissue) are generally provided. Closure of apertures in tissue, e.g., using sutures and patch closures, are common surgical operations. In some aspects, methods and devices for using tissue grippers to engage tissue portions, and subsequently biasing the tissue grippers and tissue portions towards one another by changing a configuration of a lock are generally provided. In other aspects, methods and devices for measuring a retraction force applied by tissue grippers to tissue portions are generally provided.

  • Publication number: 20240215970
    Abstract: Surgical devices and related methods for use with sutures are generally described. In some embodiments, a surgical device may include an elongated body and a plurality of through holes configured to allow a suture to pass through the plate across opposing edges of a defect site. The plate may shield neighboring tissue from tension in the suture line by re¬distributing the tension along its body. In some embodiments, the disclosed surgical devices may reduce the likelihood of defect closure failure caused by the suture pulling through a tissue defect. In some embodiments, the through holes may be located on offset parallel axes to reduce excessive suture friction and suture mismanagement. The disclosed surgical devices may be used with either interrupted or continuous suture patterns.

  • Publication number: 20230233766
    Abstract: Systems and methods for multi-chambered syringes are described. In some embodiments, a multi-chamber syringe includes a housing with an internal cavity and first and second plungers disposed at least partially within the internal cavity. The first and second plungers are slidably displaceable relative to the housing, and are associated with first and second chambers respectively. A barrier is disposed at least partially between the first and second plungers to form the first and second chambers. The barrier is slidably displaceable relative to the plungers and barrel to selectively place the first and second chambers including first and second materials respectively in fluid communication. When the barrier is displaced, the first and second materials mix in a combined volume of the first and second chambers. Displacing the first plunger, the second plunger, and the barrier may dispense the mixed materials from the combined volume.

  • Publication number: 20220409356
    Abstract: 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.

  • Publication number: 20220323637
    Abstract: Compositions and methods related to powdered hemostats that crosslink during and/or after application to a bleeding site are described. The compositions may comprise a first component comprising a polyalkylene oxide-based polymer functionalized with electrophilic reactive groups, and a second component that comprises a protein such as albumin and an optional crosslinking initiator—which may be a base or basic salt such as sodium bicarbonate. The compositions may in certain applications act as hemostats when applied in dry powder form to a bleeding wound, whereupon the first component and the second component of the composition crosslink to form a hydrogel.
