摘要:
A positionable imaging device includes a body defining a first end and a second end. The body is configured to be received within an internal body cavity. An imaging device is located at the first end of the body. A releasable fastener is coupled to the body to removably attach the imaging device to tissue within the internal body cavity. A release mechanism is coupled to the releasable fastener to detach the imaging device from the tissue.
摘要:
A method for regulating hormone production comprises placing at least one electrode in a gastrointestinal tract of a patient and recording an electrical signal during a preselected event produced by the gastrointestinal tract. The method further involves the steps of storing the electrical signal, and playing back the electrical signal by activating the electrode during the absence of the preselected event.
摘要:
L-cells may be introduced in the gastrointestinal tract. L-cells are used in the digestive process to produce a more efficient and lasting means of regulating feelings of satiation in a patient. Desired metabolic effects may be achieved by manipulating L-cells via delivery sites, frequency of delivery, or type of biological substance delivered.

A surgical instrument can be used to capture and retrieve tissue, or other specimens, from within the body of a patient through a single trocar port. The surgical instrument can include a grasper, wherein the grasper can be configured to capture a specimen, and a specimen retrieval bag, wherein the specimen retrieval bag can be configured to at least partially surround, or encapsulate, the captured specimen when the specimen retrieval bag is in a deployed position. In certain embodiments, the retrieval bag can be inverted as it is moved between undeployed and deployed positions. In various embodiments, the surgical instrument can further include a snare operably engaged with the specimen retrieval bag, wherein the snare can be configured to at least partially close the bag. A vacuum can be placed in communication with the bag to reduce the size of the bag before it is removed from the surgical site.

Methods and devices are provided for deploying and applying multiple suture anchors. In one embodiment, a surgical device is provided having a shaft configured to be introduced into a body, e.g., through a scoping device, and to deliver a plurality of suture anchors into tissue, preferably without the need to remove the shaft from the body. The shaft can have a plurality of channels, with each of the plurality of channels configured to seat at least one of a plurality of suture anchors. Each of the anchors can be removably seated in a channel such that the anchors can be removed from the device, such as by pulling on sutures attached to the respective anchors.

An implantable restriction device includes a belt and a balloon secured to the belt for engagement with tissue when the implantable restriction device is positioned about the stomach. A spacer is associated with the belt for maintaining the restriction device in a spaced relation with a staple line employed during gastric reduction surgery.
摘要:
In various surgical techniques, a bipolar forceps can be used to seal a vessel in two locations such that the vessel can be incised at a location positioned intermediate the two seal locations. The bipolar forceps can include a cutting element which can be configured to incise the vessel. In various embodiments, the cutting element can include a sharp edge which can be moved relative to the vessel. In at least one embodiment, the cutting element can be electrically connected to a source of energy. The bipolar forceps can include first and second electrodes positioned within first and second jaw members, respectively, wherein at least one of the jaw members can include a substantially tapered profile and can be configured to pull the vessel away from the surrounding soft tissue. Such jaw members can include ridges, teeth, and/or a textured outer surface configured to grip the soft tissue and/or vessel.
