  • Patent number: 11123074
    Abstract: A method is provided for operating a powered surgical stapler having a motor unit, a controller. and a stapling assembly having a closure member, a staple driver member, and a knife member. The controller receives a user input that indicates a tissue gap to be defined by the stapling assembly in a closed state. Based on the user input, the controller controls the motor unit to actuate the closure member to transition the stapling assembly to the closed state to define the tissue gap and clamp tissue therein. The controller then controls the motor unit to actuate the staple driver member to drive staples into the clamped tissue. In response to determining that the staple driver member has reached a predetermined longitudinal position, the controller controls the motor unit to initiate actuation of the knife member to cut the clamped tissue.

    Abstract: A method of creating an anastomosis includes steps of advancing a distal tip of a catheter device through a first blood vessel into a second blood vessel, while simultaneously advancing a proximal base of the device into the first vessel, contacting a wall of the first vessel with a distal blunt surface on the proximal base. A further step is to retract the distal tip so that a proximal blunt base of the distal tip contacts a wall of the second vessel, thereby capturing the two vessel walls between the blunt surfaces of the proximal base and the distal tip. A controlled pressure is applied between the two blunt surfaces to compress and stabilize the captured tissue and approximate the vessel walls. A clip is deployed through the captured tissue to hold the tissue in place during the anastomosis procedure. The anastomosis is created by applying cutting energy to the captured tissue.

  • Patent number: 10667817
    Abstract: A system for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

  • Patent number: 10631867
    Abstract: A surgical instrument includes an anvil selectively coupleable to a stapling head assembly and a trigger operable to fire staples into tissue compressed between the anvil and the stapling head assembly. In some versions, a lockout member may engage a securing feature to prevent actuation of the anvil relative to the stapling head assembly. For instance, a tab may engage a slot on an actuator, a screen door lock may provide frictional resistance or engage teeth on the actuator, a door may actuate into engagement with one or more recesses, geared teeth may mesh with teeth on the actuator, the lockout member may include a ratcheting assembly to engage actuator, and/or a push button may actuate into a recess while disengaging the lockout member. Alternatively, in some versions, the trigger actuation assembly may be disengaged prior to firing. An anvil position indicator may restrict engagement of the trigger actuation assembly.

  • Patent number: 10617414
    Abstract: A closure member for applying a closure motion to a movable jaw of a surgical instrument. In at least one form, the closure member comprises a closure body that defines an outer surface and an inner surface. The closure body further defines an upper portion that comprises an upper wall thickness between the outer and inner surfaces and a lower portion that comprises a lower wall thickness between the outer and inner surfaces. The upper wall thickness differs from the lower wall thickness. A cam surface is formed on the upper portion for selective camming contact with a portion of the movable jaw.

  • Patent number: 10588620
    Abstract: In one embodiment, a suture attachment catheter configured to repair a heart valve by inserting a suture in a valve leaflet of a beating heart of a patient includes a handle control, a flexible catheter body, and a suture attachment assembly at a distal end of the catheter body. The suture attachment assembly can include a rail between a distal clamping jaw hingedly attached to the rail, and a proximal clamping jaw. One of the proximal clamping jaw or distal clamping jaw can be selectively slideable with respect to the other on the rail using a jaw actuator of the control handle to adjust a distance between the proximal clamping jaw and the distal clamping jaw. A needle can be selectively slideable within the catheter body by using a needle actuator of the proximal handle control to penetrate a valve leaflet and insert a suture through the valve leaflet when the valve leaflet is captured between the proximal clamping jaw and the distal clamping jaw.

  • Patent number: 10568631
    Abstract: The head of a stapler for mucosectomy comprises an external goblet-shaped body (1) wherein an internal goblet-shaped body (2) is concentrically and slidingly located, at the edge of which a circular blade (3) is fixed. The internal goblet-shaped body (2) is provided with a central hole (5) wherein a rod (6) is slidingly inserted, at the end (7) of which an anvil (8; 8?) is fixed. One or more annular grooves (11), which are parallel and suitably spaced one from the other, are formed on the lateral surface of the rod (6) perpendicularly to the axis thereof. Said grooves (11) are intended to receive a portion of mucosa (9a) which is included in a purse string suture as the mucosa is tied around the rod (6). By retracting the rod (6) in the central hole (5) of the stem (2a) of the Internal goblet-shaped body (2) the mucosa to be removed is carried into the internal goblet-shaped body (2).

  • Patent number: 10517601
    Abstract: An indicator (26) includes an indicator body portion (50), a pivot support member (52), a resilient lever (54) and an anchor (66). The pivot support member (52) has a first end (52a) secured to the indicator body portion (50) and a second end (52b) secured to a first end (54a) of the resilient lever (54). The resilient lever (54) has a second end (54b) secured to the anchor (66). The pivot support member (52) is adapted to be pivotally mounted to a body portion (18) of a surgical device and the anchor (66) is adapted to be secured to the surgical device such that pivotal movement of the indicator body portion (50) from a first position to a second position effects movement of the resilient lever (54) from a relaxed configuration to a stressed configuration. In the stressed configuration, the resilient lever (54) urges the indicator body portion (50) towards the first position. The indicator body portion (50) can be integrally molded of a plastic material to define a single part of unitary construction.
