20080215089 | Stomach wall closure devices - In a method for sealing an incision in an interior body wall such as a gastrotomy opening in a stomach, a closure device is positioned within the incision. The closure device includes a seal and an anchor coupled to the seal. The seal is positioned in sealing contact against a first surface of the body wall, and the anchor is positioned against the second surface of the body wall such that a portion of the closure device is positioned. The closure device seals the incision while healing takes place. Once the incision is significantly healed, the closure device bioerodes. | 09-04-2008 |
20090012542 | SATIATION DEVICES AND METHODS FOR CONTROLLING OBESITY - Satiation devices for controlling obesity and methods of implanting same are configured to create a small satiation pouch in the proximal portion of the stomach with a narrow passage leading into the lower portion of the stomach. The small satiation pouch is configured to collect a small amount of masticated food from the esophagus and the narrow passage delays emptying of the food from the satiation pouch into the larger part of the stomach, thereby causing a feeling of fullness. | 01-08-2009 |

The pair of sections surround the esophagus at the gastro-esophageal junction thereof and to be secured together to form a tubular housing with a proximal orifice, a distal orifice smaller than the proximal orifice, and a plate adjacent the distal orifice. A portion of the housing adjacent the distal orifice is configured to elastically deform to constrict the esophagus and serve the function of the LES when a force is applied to the plate by the fundus. The proximal end portion of each mating section includes a flange portion configured to be attached to a body cavity wall. | 01-08-2009 |
20090157076 | DEVICES AND SYSTEMS FOR MINIMALLY INVASIVE SURGICAL PROCEDURES - A system for minimally invasive medical procedures includes an elongate tubular access cannula comprising an elongate tubular member having a rigid proximal portion and an articulating portion.

A dissector suitable for use with the access cannula, or other access devices, for implantation of gastric bands or for other procedures includes a pre-curved distal portion having a dissection element such as a monopolar RF conductor and/or a dissection balloon, as well as a snare. In one method, the dissector is advanced around the posterior side of the stomach to form a tunnel in the connective tissue, and the snare is then extended from the dissector to engage a portion of the band and withdraw it through the tunnel. | 06-18-2009 |
20110060183 | MULTI-INSTRUMENT ACCESS DEVICES AND SYSTEMS - A surgical access system for use in minimally invasive procedures such as single port or laparoscopic surgery. The system has a sealed base positionable in an incision formed in a body wall and at least two access tubes extending through the base. Each access tube includes a rigid tube having a fixed pre-formed shape including a bend in its distal section. The rigid tubes are restrained against pivotable movement relative to the base, but can be axially rotated and longitudinally repositioned relative to the base. A deflectable tubes extends from the distal end of each rigid tube. Each deflectable tube has a lumen for passage of a medical instrument, as well as a proximal actuator which engages a pullwire to deflect the tube when the user manipulates the instrument's handle. | 03-10-2011 |
20110066173 | PROCEDURAL CANNULA AND SUPPORT SYSTEM FOR SURGICAL PROCEDURES - A system for performing minimally invasive medical procedures includes an elongate support advanceable into a body cavity. The elongate support supports a frame that carries a pair of tool cannulas, each of which has a lumen for receiving a tool useable to perform a procedure in the body cavity. The frame is expandable to orient the tool cannulas such that they allow the tools to be used in concert to carry out a procedure at a common location in the body cavity. | 03-17-2011 |
20110112371 | MULTI-INSTRUMENT ACCESS DEVICES AND SYSTEMS - A multi-instrument access device includes a base positionable within a percutaneous opening formed in a body. Ports are positioned on the base for receiving instruments to be inserted into the body for use in a procedure. Tubular instrument tubes having steerable distal ends may be insertable through the ports for receiving the instruments and for orienting the operative ends of the instruments toward a target site. | 05-12-2011 |
20110118545 | System and method for multi-instrument surgical access - A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes a rigid tube carried by a mount. Cannulas having instrument channels and steerable distal ends extend distally from the rigid tube. During a procedure using the system, the mount is supported by an operating room fixture, and instruments are advanced through the steerable instrument channels. Manipulation of the instrument handles engages actuators positioned on the mount, which steer the distal ends of the cannulas through the action of pull cables. The distal ends of the instruments may thus be steered within the body by the distal ends of the steerable cannulas. | 05-19-2011 |
20110166482 | SYSTEM AND METHOD FOR TRANSVASCULARLY STIMULATING CONTENTS OF THE CAROTID SHEATH - Methods and systems are disclosed for stimulating contents of the carotid sheath using an intravascular pulse generator and lead. The lead carries an energy delivery device such as an electrode, which is anchor within the portion of the internal jugular vein that is disposed within the carotid sheath. The energy delivery device is energized to transvenously direct energy to target contents of the carotid sheath external to the internal jugular vein. Such target contents may include nervous system elements associated with the carotid sinus baroreceptors, the carotid sinus nerve and associated nerve branches, and or the vagus nerve and associated nerve branches. The system may be used to control blood pressure and/or to lower heart rate and may be suitable for treatment of hypertension, heart failure, or other conditions. | 07-07-2011 |
20120116286 | INTESTINAL SLEEVES AND ASSOCIATED DEPLOYMENT SYSTEMS AND METHODS - An intestinal implant includes a proximal anchor self-expandable from a radially compressed position to a radially expandable position for engagement with a wall of the intestinal lumen and a flexible sleeve coupled to the anchor. The sleeve is implanted with the anchor downstream from the pylorus and the sleeve extending further downstream through the intestinal lumen. | 05-10-2012 |
20120221014 | TRANSVASCULAR ELECTRODE SYSTEM AND METHOD - A transvascular electrode system includes an expandable electrode-carrying anchor. The anchor is intravascularly advanced in a compressed position to a first site in a blood vessel. A first portion of the anchor expands to position an electrode against the vessel wall, while a second portion remains is compressed. Mapping is performed by delivering stimulation energy from the electrode and measuring the response (e.g. blood pressure, heart rate, and/or related parameters). The first portion is at least partially collapsed and the electrode system is moved to a second site. The first portion is expanded to position the electrode into against the vessel wall, while the second portion remains compressed. Additional mapping is performed. The process is repeated until the anchor electrode position is optimized, at which point the second portion of the anchor is expanded to chronically retain the electrode in the vessel. | 08-30-2012 |
20130018247 | INTRAVASCULAR ELECTRODES AND ANCHORING DEVICES FOR TRANSVASCULAR STIMULATION - An intravascular electrode device for use in neuromodulation includes an anchor expandable from a radially compressed position to a radially expanded position.

A flex circuit is coupled to the anchor and comprises a flexible insulative substrate, a plurality of electrodes carried by the substrate, and a plurality of conductive traces carried by the substrate, each trace electrically coupled to an electrode and a conductor. Expansion of the anchor within a blood vessel biases the electrodes into contact with the surrounding blood vessel wall. An exemplary anchor includes a first portion having expansion forces sufficient to bias the electrodes against the vessel wall for mapping and chronic stimulation, and a second portion having greater radial expansion forces sufficient to chronically engage the vessel wall once an optimal electrode location has been selected. | 01-17-2013 |
