摘要:
Devices and related methods are provided for the controlled delivery of a therapeutic to a targeted location within a body. More particularly, methods and devices are provided for controlling the rate of passage of an orally administered pill through a body, as well as for controlling the delivery of a therapeutic within the pill at a specific location within the body. Various types of devices, generally referred to herein as “catchers,” are provided that can actively catch a pill as it passes through a body. The catcher can hold the pill at a specific location within the body until a predetermined event occurs, such as partial or complete administration of a therapeutic within the pill. The catcher can then release the pill upon command and/or upon the occurrence of the predetermined event to allow the pill to pass out of the body. In other embodiments, various types of pills are provided that can actively engage a catcher and remain engaged with the catcher until a predetermined event occurs.

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.
摘要:
A device, including an implant for placement within a hollow body organ. The implant includes a member having an undeployed shape for delivery within a hollow body and one or more deployed shapes for implantation therein. The member has sufficient rigidity in its deployed shape to exert an outward force against an interior of the hollow body so as to bring together two substantially opposing surfaces of the hollow body. The device includes a means for changing the deployed shape of the member while implanted within the hollow body. The means includes an antenna configured to wirelessly communicate with an external device. The external device is configured to communicate telemetrically with the member. The device further includes at least one means to limit rotational movement of the antenna relative at least one of the member and the external device.

An implant for placement within a hollow body organ. The implant includes an implantable distension device having an undeployed shape for delivery within a hollow body and one or more deployed shapes for implantation therein. The implantable distension device has sufficient rigidity in its deployed shape to exert an outward force against an interior of the hollow body so as to bring together two substantially opposing surfaces of the hollow body. The implant includes a powered means for changing the deployed shape of the implantable distension device while implanted within the hollow body. The implant also includes an implantable sensing device in communication with the implantable distension device and configured to sense a parameter related to the implantable distension device and to communicate the parameter to a filter, the filter transmits a selected portion of the parameter to a data storage device.
摘要:
Devices and methods are provided for forming and securing a tissue plication. More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a tissue acquisition and fixation system is described that includes a staple applying assembly having first and second jaws, and a tissue acquisition member that extends substantially parallel to a plane running through the first and second jaws. The tissue acquisition member is effective to engage and position tissue between the first and second jaws, and the jaws are effective to apply at least one staple to the tissue engaged therebetween.

Devices and methods are provided for forming and securing a tissue plication. More particularly, the devices and methods of the present invention can be used to create tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a tissue acquisition and fixation system is disclosed that includes an elongate shaft, an end effector coupled to the elongate shaft and having first and second jaws, and a tissue acquisition member coupled to the end effector by a linkage assembly. At least a portion of the linkage assembly and tissue acquisition member are slidably movable in a direction parallel to a longitudinal axis of the jaws. Further, the tissue acquisition member is vertically movable relative to the end effector such that a distance between a longitudinal axis of the tissue acquisition member and the jaws can be adjusted.
摘要:
Self-positioning of at least a portion of a transdermal electrical stimulation patch within a target area (e.g., supraclavicular fossa region) of a human body to activate a depot of brown adipose tissue therein. An electric field is generated using the electrical stimulation patch to activate the brown adipose tissue within the supraclavicular fossa region of the body. The patch is self-positioned using one or more anatomical points (e.g., anatomical landmarks and/or anatomical features) or markings on the body. Brown adipose tissue may also be activated by applying an electrical signal to a body piercing partially implanted proximate a target area in which the tissue is disposed.

More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a method of acquiring and fixating tissue is disclosed that includes inserting a surgical device having first and second jaws and a tissue acquisition member into a body lumen, positioning the device in a first position in which the jaws extend substantially parallel to a tissue surface, drawing tissue through the jaws by moving the tissue acquisition member away from the jaws, and driving at least one fastener through the tissue disposed between the jaws.
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.
