Disclosed herein is a tissue engaging surgical tool that is configured to selectively hold or grasp a portion of tissue with a suction cup or flexible end portion. The device is configured to increase or decrease pressure between the flexible end portion and tissue that the end portion is held against, thereby creating a releasable suction or vacuum force.

An apparatus and method for an articulating microsurgical instrument is disclosed herein. The articulating microsurgical instrument may be configured to be operable with a Doppler probe, bone grasper, soft tissue grasper/dissector, scissors, flexible forceps, or a suction/irrigation line configured to provide tools within a surgical location that can be adjusted to a desired angle of operation. A tip assembly may comprise an articulating portion at a distal tip and the articulating portion may be configured to deflect upon actuation of an articulation control. The articulation control may be a trigger assembly or a roller wheel. A bayonet-style handle may include a set of posts configured to interact with the one or more control wires during actuation of the articulation control. One or more control wires may be housed in a lumen and actuated using a articulation control of a handle assembly.

Particular embodiments disclosed herein provide a surgical instrument comprising a device having a proximal end and a functional end configured to be inserted into a body part, an assembly having a proximal end and a distal end, a shaft coupled to the proximal end of the assembly, the shaft having a shaft housing, a bearing positioned around the assembly, wherein the bearing is configured to slide over the assembly, a hub having a sleeve tube. The basket comprises a plurality of grooved levers, each grooved lever having a proximal end received by the shaft housing and a distal end coupled to a tip of the basket, wherein compressing one or more of the plurality of grooved levers moves the bearing and the hub relative to the shaft and toward the functional end of the device, causing the sleeve tube to transition the device from the deactivated state to an activated state.

A device includes a first arm having a first rotating member including a first gear coupled thereto and a first rotation imparting member fixed thereto, a second arm pivotally coupled to the first arm at proximal ends of the first arm and the second arm, the second arm having a second rotating member including a second gear coupled thereto and a second rotation imparting member fixed thereto, wherein when the first arm and the second arm are brought towards each other, the first rotation imparting member engages with the second gear to cause the second rotating member to rotate in a first direction, and the second rotation imparting member engages with the first gear to cause the first rotating member to rotate in a second direction, opposite the first direction.

A device includes a body configured to be placed on an eye and multiple tine assemblies configured to secure the body to and release the body from the eye. The body includes multiple corners and multiple sides. Each corner includes a passage through the corner. Each side connects an adjacent pair of corners. Each tine assembly includes a twist pick configured to be inserted through one of the passages. Bottom surfaces of the sides are raised relative to bottom surfaces of the corners such that the bottom surfaces of the sides are spaced apart from the eye when the bottom surfaces of the corners are resting on the eye. Each of at least one side includes multiple openings configured to allow manipulation of a position of the body and a groove configured to receive a projection from a surgical tool in order to position the surgical tool on the eye.

The invention relates surgical abdominal methods of treating obesity in a patient by implanting a volume filling device that, when implanted in a patient, reduces the food cavity in size by a volume substantially exceeding the volume of the volume filling device. Also disclosed is a laparoscopic instrument for providing a volume filling device to be invaginated in the stomach wall of a human patient to treat obesity.
