摘要:
A system for mapping electrical activity of a patient's heart. The system includes a set of electrodes spaced from the heart wall and a set of electrodes in contact with the heart wall. Voltage measurements from the electrodes are used to generate three-dimensional and two-dimensional maps of the electrical activity of the heart.

The present invention provides devices and methods for attachment of an endolumenal gastrointestinal device, such as an artificial stoma device, a gastrointestinal bypass sleeve or other therapeutic or diagnostic device, within a patient's digestive tract. In one application of the invention, an endolumenal bypass sleeve is removeably attached in the vicinity of the gastroesophageal junction to treat obesity and/or its comorbidities, such as diabetes. The bypass sleeve may be at least partially deployed by eversion.

A reduced pressure treatment system includes a filament delivery conduit having a distal end positioned at a subcutaneous tissue site of a patient and a proximal end positioned extracorporeal to the patient. A continuous filament is positioned in the filament delivery conduit such that one end of the continuous filament extends from the proximal end of the filament delivery conduit and another end of the continuous filament extends from the distal end of the filament delivery conduit. The continuous filament forms a filament mass adjacent the tissue site. A reduced pressure delivery conduit is adapted to fluidly communicate with a reduced pressure source and the filaments mass to deliver a reduced pressure to the tissue site through the filament mass.
摘要:
A reduced pressure delivery system is provided and includes a primary manifold, a blockage prevention member, and first and second conduits in fluid communication with the primary manifold. The primary manifold includes a flexible wall surrounding a primary flow passage and is adapted to be placed in proximity to a tissue site. The blockage prevention member is positioned within the primary flow passage. A plurality of apertures is disposed in the flexible wall to communicate with the primary flow passage. The first conduit is fluidly connected to the primary flow passage to deliver reduced pressure through the primary flow passage and the plurality of apertures. The second conduit includes an outlet proximate the primary flow passage or an outlet of the first conduit to purge the primary flow passage or first conduit to prevent blockages.

A reduced pressure delivery system for applying a reduced pressure to a tissue site is provided. The system includes a manifold having a plurality of flow channels. The manifold is configured to be placed adjacent the tissue site. A first conduit is in fluid communication with the flow channels of the manifold to deliver a reduced pressure to the flow channels. A second conduit is in fluid communication with the flow channels of the manifold and is operably connected to a valve. The valve selectively purges the second conduit with ambient air when the valve is positioned in an open position, and a controller is operably connected to the valve to place the valve in the open position for a selected amount of time at a selected interval during delivery of reduced pressure through the first conduit.
摘要:
A method of administering a reduced pressure tissue treatment to a tissue site includes percutaneously inserting a tube through a skin tissue of a patient to place a distal end of the tube adjacent the tissue site, the tube having at least one passageway. A balloon associated with the tube is positioned adjacent the tissue site, and the balloon is inflated to dissect and form a void adjacent the tissue site. A manifold having a plurality of flow channels is delivered through the passageway to the tissue site. The manifold is positioned such that at least one of the flow channels is in contact with the tissue site, and a reduced pressure is applied to the tissue site through the flow channels of the manifold.

Aspects of this invention disclose devices and methods for attachment of a gastrointestinal sleeve. In some embodiments, the attachment device comprises a flexible cuff, a gastrointestinal sleeve interface, and a gastrointestinal sleeve. Some aspects of the invention contemplate the use of T-tags for attachment of the cuff to tissue. In some aspects of the invention, attachment of the sleeve to the cuff is achieved using various fasteners.
摘要:
Apparatus and methods are described for treatment of morbid obesity using minimally invasive techniques. The apparatus includes a system of components that may be used separately or in combination for effectively reducing stomach volume, bypassing a portion of the stomach and/or small intestines, reducing nutrient absorption in the stomach and/or small intestines and/or depositing minimally or undigested food farther than normal into the intestines, thereby stimulating intestinal responses. The components described include an artificial stoma device, a gastric sleeve device, an intestinal sleeve device and a combined gastrointestinal sleeve device.
摘要:
A method of acquiring and mapping physiological data in a heart chamber includes inserting a catheter into the heart chamber. Physiological data in the heart chamber is acquired with the catheter. The position of the catheter is determined, and the location of the acquired physiological data is determined using the position of the catheter. Information related to the three-dimensional geometry of at least a portion of the heart chamber is received, and a three-dimensional map of the physiological data is created and superimposed on a geometrical representation of the three-dimensional geometry information.
