  • Procedural cannula and support system for surgical procedures
    Patent number: 7833156
    Abstract: 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 using pivotable frame members 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.

  • Satiation devices and methods
    Patent number: 7833280
    Abstract: A device for inducing weight loss in a patient includes a tubular prosthesis self-expandable from a collapsed position in which the prosthesis has a first diameter to an expanded position in which the prosthesis has a second, larger, diameter. In a method for inducing weight loss, the prosthesis is placed in the collapsed position and inserted into a stomach of a patient. The prosthesis is allowed to self-expand from the collapsed position to the expanded position and into contact with the walls of the stomach, where it induces feelings of satiety and/or inhibits modulation of satiety-controlling factors such as Ghrelin.

  • SHEATHLESS EMBOLIC PROTECTION SYSTEM
    Publication number: 20100121374
    Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be compressed for insertion thereof through a patient's vasculature so as to cross the stenosis in a low profile, and to enable release of compression thereof for expansion and deployment of the device at a location distal to the interventional procedure site.

    Publication number: 20100100109
    Abstract: A prosthetic device is described that is positionable within the gastro-esophageal junction region of a patient. The prosthetic device includes a proximal opening and a distal orifice that is adjustable in size prior to and/or following implantation. During use, the prosthetic device is attached to tissue of the gastro-esophageal junction region of the patient, with the device positioned such that food ingested by the patient passes from the esophagus through the proximal opening into the interior of the prosthetic device, and eventually exits the prosthetic device via the distal opening.

  • CONVERTIBLE DELIVERY SYSTEMS FOR MEDICAL DEVICES
    Publication number: 20100049305
    Abstract: A delivery system for a medical device or other devices to be deployed within a biological body including a sheath having a longitudinal joint. The joint can be either resealable or non-resealable. The joint remains intact during delivery of the medical device, thereby facilitating accurate delivery of the medical device. During removal of the sheath, the joint is separated, thereby permitting the sheath to be peeled from the medical device while maintaining the position of the device. The delivery system allows a single operator to deploy the medical device and remove the sheath.

  • SYSTEM AND METHOD FOR TRANSVASCULARLY STIMULATING CONTENTS OF THE CAROTID SHEATH
    Publication number: 20100023088
    Abstract: 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.

  • SATIATION DEVICES AND METHODS
    Publication number: 20100016988
    Abstract: A satiation device is described which includes a sheath or liner extending from the proximal or middle stomach to the distal antrum. Food ingested by the patient passes through the sheath or liner, thereby minimizing contact between the ingested food and the stomach. It is believed that over time, reduced contact between food and the stomach will result in decreased Ghrelin production by the patient and a consequent decrease in appetite. In some embodiments, the satiation device may also include a proximal pouch and/or a distal bypass tube.

  • System and method for anchoring stomach implant
    Publication number: 20080208355
    Abstract: A gastric implant system includes a gastric implant such as a restrictive pouch or a gastric balloon, an anchor passable through the mouth and stomach and further through the stomach wall into engageable with abdominal wall tissue. When the anchor is engaged to abdominal wall tissue, the stomach wall and abdominal wall are brought into contact with one another such that a proximal portion of the anchor extends into the stomach interior while a distal portion of the anchor remains engaged to the abdominal wall. A locking element coupled to the proximal section of the anchor is used to maintain contact between the stomach wall and abdominal wall. The gastric implant is advanced through the oral cavity into the stomach and is coupled to the anchor.
