摘要： A surgical instrument that may include a housing, a transducer engaged with the housing which can produce vibrations, and an end-effector engaged with the transducer. The surgical instrument can include an adjustable sheath extending from the housing where the sheath is movable relative to the distal tip of the end-effector and where the distance between the distal tip of the sheath and the distal tip of the end-effector can enable the sheath to act as a depth stop. The sheath can be adjusted such that, when the distal tip of the sheath contacts the tissue or bone being incised, the surgeon can determine that the appropriate depth of the incision has been reached. In other embodiments, the end-effector can be moved with respect to the sheath to adjust the distance between the distal tip of the end-effector and the distal tip of the sheath.

摘要： Devices and methods for modifying stomach volume include the formation of intragastric slots for wrapping one or more portions of the fundus therethrough with minimal interference with nerves and vasculature flow. Intragastric space occupying devices expand with environmental changes brought about by natural conditions inherent to the digestive cycle such as with changes in pH. Extragastric volume occupying balloons are placed into folded stomach sections. The balloons are fluidly coupled to external gastric filling devices. In yet another set of embodiments, methods and devices provide adjustable gastric volume reduction fundal wraps. In one embodiment, a device is placed in the fundus for Nissen fundoplication and permits postoperative adjustment to reach desired weight loss. Intragastric and extragastric balloons are optionally incorporated.

摘要： A tissue dicing and separation device comprises a housing having an interior that receives tissue for dicing and separation. The device includes a blade assembly connected to a motor and solenoid. The solenoid reciprocates the blade assembly while the motor clocks the blade assembly during each reciprocation cycle. This reciprocating and clocking action of the blade assembly dices and/or minces the tissue. The housing is filled with a fluid and then the blade assembly is continuously rotated to create a vortex within the housing. The vortex causes the diced tissue particles to separate by particle size. Outlets at different positions along the housing permit withdrawal of a slurry of fluid and tissue particles with the tissue particles having a desired size range. The obtained slurry may be used in conjunction with a fistula plug treatment device and method.
