摘要:
An apparatus and method for performing needle guided interventions and especially needle guided dilations of tissue to create a therapeutic conduit between two luminal organs or structures. The device is particularly useful for creation of an artificial lumen between two hollow body organs using the working lumen of an endoscope.
摘要:
Tissue anchors comprise a woven filament braid body having an elongated tubular configuration and a foreshortened configuration where proximal and distal ends of the body expand radially into double-walled flange structures while leaving a cylindrical saddle region therebetween. The tissue anchors are deployed through penetrations between adjacent tissue layers, where the flanges engage the outer surfaces of the tissue layers and the saddle region resides within the tissue penetrations.
摘要:
Method and apparatus for treatment of morbid obesity by placement of a series of flow reduction elements in the small intestine to induce satiety are disclosed. The flow reduction elements restrict the movement of partially digested food and reduce the flow rate through the small intestine which causes the emptying of the stomach and the duodenum to occur slower. The flow reduction elements are attached to an elongated tube and are constructed from various shapes and configurations. The flow reduction elements may be inflated with fluid or may be constructed from self-expandable materials. The device is anchored in the antrum of the stomach with an anchoring member. The transoral gastric device can be inserted with a delivery catheter through the working lumen of an endoscope or alongside an endoscope and may be removed with the aid of an endoscope if desired.
摘要:
A housing is described to introduce an endosurgical or endoscopic instrument to a surgical site in a sterile manner with a sleeve that is filled with disinfecting fluid into which a the instrument can be placed and the sleeve has a membrane at one end that can be punctured by the instrument.
摘要:
A tissue penetrating device for endoscopy or endosonography-guided transluminal interventions using an automated spring-loaded mechanism is taught. Various modifications and uses including tissue anchoring, affixing, and creating an anastomosis are explained.

摘要:
A device and method for illuminating, viewing and monitoring internal body surfaces without an external attachment is disclosed. The present device includes a housing that is suitable for swallowing by the patient or by placement with an endoscope, either through the working lumen or attached to the endoscope. The device has an optical or sensor element coupled to the housing that can be used for illuminating, visualizing or monitoring a body surface. A power source may be located in the housing to provide power to the optical or sensor element. The device may be secured to the body using securement elements.
摘要:
The invention relates to a device for endoscopic fine needle biopsy, in which control of the needle (2) is automatized by using a prestressed needle. On release of the spring (8), the needle shoots forward in the direction of the tissue, overcoming frictional force as a result of high acceleration. This reduces the danger of breaking the needle.
