摘要:
A method for creating a plication within a hollow organ. The method uses an elongated member having an end effector at its distal end. The end effector has an outer cylinder having at least one opening in its cylindrical wall, and an inner cylinder having at least one opening in its cylindrical wall. The inner cylinder is at least partially disposed within the outer cylinder such that the apertures can at least partially overlap. The cylinders are rotatable with respect to each other. The method includes the step of inserting the end effector within an organ of a patient such that it is in contact with tissue. The method also involves applying vacuum through the elongated member so as to dispose tissue within the inner cylinder. The method also involves creating a plication by rotating the cylinders with respect to each other.

A method for creating a plication within a hollow organ. The method uses an elongated member having an end effector attached to its distal end. The end effector has a substantially hollow housing, a fixed jaw extending distally from the housing, and a retractable jaw located within the housing. The method involves the step of inserting the end effector within an organ of a patient such that it is in contact with tissue. The method also involves applying vacuum through the elongated member so as to dispose tissue on the fixed jaw and at least partially within the housing. The method also involves creating a plication by sliding the retractable jaw so that it juxtaposes the fixed jaw.
摘要:
A mechanism for feeding a fastener including a housing having a longitudinal axis and at least one fastener within the housing. The fastener has a crown and at least two legs extending therefrom. The fastener is disposed within the housing in a first plane parallel to the longitudinal axis. The mechanism includes an elongated actuator disposed within the housing. The actuator has a shaft substantially parallel to the longitudinal axis of the mechanism and rigidly spaced from the fastener in a second plane. The actuator has at least one radially extending advancer disposed along a length thereof, and a mechanism for rotating the actuator so that the advancer engages the fastener.
摘要:
Methods and devices regulate the activation of ghrelin hormones within a stomach in order to treat weight disorders, to promote learning and memory functions, to treat stress-induced depression, and to control sleep duration. In one embodiment, a method for regulating activation of ghrelin hormones within a stomach comprises a means for isolating non-activated ghrelin hormones from food content and dietary lipids within the stomach. These means for isolating may take any number of forms and may comprise one or more of a surgical procedure, an implanted device, or an ingestible substance.
摘要:
A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains a plurality of surgical fasteners. The surgical fasteners have a base, and two legs extending away from the base, wherein the legs have distal end segments. The fastener has a first shape wherein the distal end segments bend towards each other so that they are adjacent and form the fastener into a first loop. The fastener has a second shape wherein the distal end segments are spaced apart from each other along substantially an entire length thereof. The fastener also has a third shape wherein the distal end segments bend towards each other in so that they are adjacent and form the fastener into a second loop wherein the second loop having a width greater than a width of the first loop. The applier includes a means for forming the fastener into the second and third shapes.
摘要:
A fastener applying device for surgically attaching tissue together. The device includes a staple housing having a proximal end attached to a handle, a distal end and a longitudinal axis therebetween. There is at least one fastener within the housing. The device includes an anvil movable within the staple housing. The anvil has a proximal position and a distal position, wherein when in the distal position a distal end of the anvil extends distal to the distal end of the staple housing by a distance. The device further includes an adjustment nut connecting the staple housing to the handle, wherein rotation of the adjustment nut changes the distance.
