Abstract

Surgical devices are provided having power-assisted or fully powered jaw closure. The devices herein generally include a handle portion, an elongate shaft, and an effector having first and second jaws configured to engage tissue. A motor and one or more compression springs can be operatively coupled, and activation of the motor can compress the spring(s) to reduce the amount of user supplied force to compress tissue between the jaws. In some embodiments, the devices can be configured to regulate an amount of compression applied by the jaws prior to, during, and/or after cutting of the tissue to promote hemostasis. For example, the devices can include sensors, processors, and/or other components that analyze data indicative of tissue type and tissue load. Based on this feedback, the device can automatically adjust the amount of compression or energy applied to the tissue to seal the tissue.

Abstract

Various embodiments are directed to systems and methods for providing a drive signal to a surgical device for treating tissue. A surgical generator may deliver the drive signal according to a first composite load curve. The surgical generator may receive a first tissue measurement indicating a property of the tissue at a first time during the delivery of the drive signal, receive a second tissue measurement indicating the property of the tissue at a second time during the delivery of the drive signal after the first time, and based on the first and second tissue measurements, determine a difference in the property of the tissue between the first time and the second time. When the difference in the property of the tissue exceeds a difference threshold, the generator may deliver the drive signal according to a second composite load curve that is more aggressive than the first composite load curve.

Abstract

A surgical implant for insertion of the same into a biological lumen. The implant (900) has an outer ring (915) having an outer wall and an inner wall the outer ring disposed about a central axis. The implant further has a flexible inner ring (925) adjacent to the outer ring inner wall extending annularly from the inner wall toward the central axis (950) and defining an annular opening (960) about it. The implant comprises a first plurality of magnets (920) embedded in the flexible ring (925) and arranged annularly around the central axis, and a second plurality of magnets (930) disposed about the central axis and located between the opening (960) and the first plurality of magnets (920). The implant is acting as a valve biased to a closed state. The interaction between the pluralities of magnets is such that normal peristalsis forces individual magnets of the two pluralities of magnets to move away from each other thus creating an opening for the passage of food.

Abstract

Various surgical devices are provided having mechanisms for preventing premature actuation of a cutting mechanism. These devices generally include a handle having one or more actuators and an effector disposed at a distal end of the device and configured to grasp tissue. When the end effector is in an open position, a firing actuator can be positioned so that it cannot be actuated by a user. For example, the firing actuator can be obstructed by a shield or arm when the end effector is in the open position. In other embodiments, the firing actuator can be hidden in a recess formed in the closure actuator until the end effector is moved to the closed position. When the end effector is in the closed position, the firing actuator can be engaged to advance a cutting mechanism, thereby cutting the tissue grasped by the end effector.

Abstract

An instrument (100) for clamping a surgical clip (10) has a handle assembly (170), a shaft assembly (140), and an end effector (110). The handle assembly has a trigger (174) and an articulation knob (172). The shaft assembly has an outer ground tube (160), a middle articulation tube (150), and a push/pull tube (142) disposed within the middle articulation tube. The trigger is operable to cause longitudinal translation of the push/pull tube. The outer ground tube and the middle articulation tube present mating angled faces (152,162) sloped in opposing directions. Rotation of the articulation knob causes rotation of the middle articulation tube. Rotation of the middle articulation tube changes the orientation of the angled faces and thus causes articulation of the middle articulation tube and the push/pull tube.

Abstract

A duodenal sleeve assembly comprises a sleeve, an expandable sealing member, a tether, and an expandable anchor. The sleeve is secured to the sealing member. The tether couples the anchor with the sealing member. A deployment instrument comprises a shaft assembly, a first retention member, and a second retention member. The first retention member selectively secures the sealing member to the shaft assembly. The second retention member selectively secures the anchor to the shaft assembly. When the first retention member is relelased, the sealing member expands outwardly to seal the proximal end of the sleeve against the mucosa of the patient's duodenum. When the second retention member is released, the anchor expands outwardly within the stomach to anchor the sleeve assembly relative to the stomach. The tether traverses the pylorus. The sleeve isolates chyme from enzymes in the duodenum; and the mucosa of the duodenum from nutrients in the chyme.

Abstract

An end effector comprises a first jaw, a second jaw, a firing beam, and a lockout feature. The second jaw pivots relative to the first jaw from an open position to a closed position. The firing beam has a sharp distal end and translates between the first and second jaws. The firing beam translates from a proximal position to a first distal position to pivot the second jaw to the closed position. The end effector applies bipolar RF energy when the firing beam is in the first distal position. The firing beam then translates to a second distal position to sever tissue captured between the first and second jaws. The lockout feature prevents the firing beam from advancing from the first distal position to the second distal position until the lockout feature is actuated.
