  • Publication number: 20160250055
    Abstract: A method for controlling appetite by means of a satiation device is disclosed. The device, which includes a flexible webbing defining proximal and distal openings and a biasing structure, is attached to the patient's stomach with the proximal opening positioned adjacent and below the patient's gastro-esophageal junction. The biasing structure imparts pressure against the wall of the patient's stomach adjacent the gastro-esophageal junction.

  • Patent number: 9358144
    Abstract: A device for inducing weight loss in a patient includes a tubular prosthesis positionable at the gastro-esophageal junction region, preferably below the z-line. In a method for inducing weight loss, the prosthesis is placed such that an opening at its proximal end receives masticated food from the esophagus, and such that the masticated food passes through the pouch and into the stomach via an opening in its distal end.

  • Patent number: 9314361
    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 engagement 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 sued 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.

  • Patent number: 9248038
    Abstract: Various methods and devices are described for retaining a medical implant within a body cavity. According to one aspect, at least a portion of a medical implant is positioned within a body cavity, and a wall of the body cavity is re-shaped such that the re-shaped wall prevents migration of the medical implant out of the body cavity. The re-shaped body wall may form a tissue pocket, tunnel, or other barrier against migration of the implant.

  • Publication number: 20160022464
    Abstract: Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach.

  • Publication number: 20150342772
    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.

  • Publication number: 20150320580
    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.

  • Patent number: 9126048
    Abstract: A neuromodulation system for treating acute heart failure syndromes includes a first catheter having a parasympathetic therapy element adapted for positioning within a first blood vessel such as a superior vena cava, and a second catheter sympathetic therapy element adapted for positioning with a second, different, blood vessel such as the pulmonary artery. The catheters comprise a system in which one of catheters is slidably disposed over the other of the catheters. The system may further be slidably disposed over a third elongate element such as a Swan-Ganz catheter positionable within a pulmonary artery, such that the Swan-Ganz may be used for monitoring parameters such as blood pressure and cardiac output during neuromodulation therapy.

  • Patent number: 9067071
    Abstract: A method of treating autonomic imbalance in a patient includes energizing a first therapeutic element disposed in a superior vena cava of the patient to deliver therapy to a parasympathetic nerve fiber (e.g. vagus nerve), and energizing a second therapeutic element disposed within the superior vena cava to deliver therapy to a sympathetic cardiac nerve fiber. A neuromodulation system includes a parasympathetic therapy element adapted for positioning within a blood vessel, a sympathetic therapy element adapted for positioning within the blood vessel; and a stimulator to energize the parasympathetic therapy element to deliver parasympathetic therapy to a parasympathetic nerve fiber disposed external to the blood vessel and energize the sympathetic therapy element within the blood vessel to deliver sympathetic therapy to a sympathetic nerve fiber disposed external to the blood vessel. The therapy decreases the patient's heart rate and elevates or maintains the blood pressure of the patient.

  • Publication number: 20150105629
    Abstract: A system for performing multi-tool minimally invasive medical procedures through a single instrument port in a body cavity includes a pair of steerable tool cannulas extending from a rigid tube that is supported by an operating room fixture. The rigid tube is extendable through an incision to position distal ends of the rigid tube and tool cannulas within a body cavity. Each tool cannula has a lumen for receiving a corresponding surgical instrument so that an end effector of the each instrument may be used within the body cavity. Control devices are operatively associated with each tool cannula and include ports for receiving the surgical instruments. User manipulation of the handles of the surgical instruments results in steering of the tool cannulas, and thus the surgical instruments, within the body cavity.

  • Patent number: 8972015
    Abstract: An intravascular electrode system includes an expandable anchor and a flexible substrate which carries at least one electrode. The anchor is positioned in a blood vessel and expanded to an expanded position to bias the electrode in contact with the vessel wall. The flexible substrate may be longitudinally withdrawn from its position between the anchor and the vessel wall without removing the anchor from the blood vessel. A second flexible substrate may be longitudinally inserted into position between the anchor and vessel wall as replacement for the first substrate.
