Occluding Clip, Clamp, Or Band Patents (Class 606/157)
  • Publication number: 20090182357
    Abstract: The present invention relates to a device for intermittently obstructing a bodily opening, such as a gastric opening, and includes a proximal member connected to a distal member by a tether. The proximal member includes an apron member surrounding a first occluding member, which is formable from an elongated and narrower configuration to a contracted or expanded but wider configuration. When employed in the stomach, the device of the present invention is arranged transluminally, with the distal member disposed in the duodenum and the proximal member disposed against the pyloric valve, intermittently occluding the pyloric valve and preventing or delaying the flow of gastric contents through the pyloric valve. In certain embodiments, a reservoir may be included for releasing a substance of interest, for example for releasing insulin from a reservoir disposed in the distal member. Sensors, actuators, and data transmission devices may also be included.

  • Publication number: 20090131958
    Abstract: A surgical clamping device for hollow anatomical structures such as, essentially, blood vessels, but also tracheas, intestines, etc. This device comprises three initially independent parts, namely two jaws, each jaw being formed of an elongate member having distal and proximal ends, and a mandrel that can be slipped over the proximal ends of the two jaws and that is able to bring the axes of the two jaws closer together, thus pinching an anatomical structure. The mandrel comprises a distal, pinching part and a proximal, handling part, these two parts being joined together by a locking part, the jaws being bendable at the level of the locking part when the clamp is activated, the distal, pinching part of the mandrel remaining in place by friction on the jaws when it is unlocked from the proximal, handling part. This surgical clamping device applies more particularly to the clamping of the aorta.

  • Publication number: 20090054917
    Abstract: A device for clamping off organic tissue has a tissue clamp with clamping bars in holders. A proximal clamping bar can be displaced in a guide groove of an application crosspiece by a tappet, while the distal clamping bar maintains its position until the tissue has been clamped off. The clamping bars have guide pin, or the distal clamping bar has a fixation shoulder. The pins or shoulder fit into crosswise grooves in the application crosspiece, and thus the clamping bars can be inserted into them vertically. The proximal clamping bar has a holder pin on its base that engages into a holder bore of the distal clamping bar. This produces a force-fit and shape-fit connection with this bore, while simultaneously clamping off the organic tissue. The guide pins shear off if the force required to clamp off the organic tissue is exceeded.

    Abstract: An implantable vessel occlusive device and method for occluding a vessel are described, for example to occlude the urethra or bladder neck. The devices and methods described utilize an occlusive member connected to a control mechanism. The occlusive member is reversibly changed from a non-occlusive condition to an occlusive condition, for example by depressing an activation button contained within a resilient, elastomeric cover surrounding the control mechanism. In the occlusive position, an initial tension is applied to the occlusive member through a tensioning suture. The tension is translated into an occlusive pressure applied to the urethra or bladder neck that is sufficient to prevent urinary leakage. The non-occlusive position can be obtained by depressing the de-activation button. The occlusive member is constructed to allow elution of drugs, such as may be required to combat infection or tissue encapsulation from its surface.

  • Publication number: 20080275480
    Abstract: An adjustable band or clamp or non-adjustable clamp is placed about the greater curvature of the stomach in a vertical orientation. The band or clamp completely compartmentalizes the stomach between a small vertical pouch and the fundus and body of the stomach. The fundus and body of the stomach are excluded from nutrients and are separated from a long narrow channel where the food travels. A small passage at the level of the antrum allows gastric juices to empty from the fundus and body of the stomach. The clamp may be applied during open surgery in laproscopic surgery or using a single port technique, or through any natural orifice in NOTES (Natural Orifice Transluminal Endoscopic surgery) or using a hybrid surgical technique.

  • Publication number: 20080269788
    Abstract: A medical device for clamping the stomach in morbid obesity surgery consists of a silicone frame that is essentially U-shaped, having opposing legs self-hinged to a bight portion interconnecting the legs. The opposing legs have sufficient stiffness to permit limited bending and have inner surfaces that sealingly carry an inflatable balloon which can be selectively inflated or aspirated after the device has been clamped to the stomach to adjust the gastric restriction stoma. A flexible latch member carried by one of the legs has at least one serration which is inserted into a latch cavity of the opposing leg to lock the opposing legs in fixed spaced relationship. Lumens within the legs communicate with a fluid supply source and respective inflatable balloon for selective inflation or aspiration of the inflatable balloons. The medical device for clamping the stomach may be self-adjusting upon distention and contraction of the proximal stomach.

  • Publication number: 20080262522
    Abstract: This invention provides the instrumentation and method to perform a percutaneous restrictive bariatric procedure with very low associated risks as compared to other types of bariatric surgery because the procedure is truly minimally invasive. The procedures of the present invention are performed percutaneously and do not rely on laproscopic or endoscopic guidance. The procedures of the present invention percutaneously restrict the stomach by decreasing the size of the pouch and delay emptying of the pouch by reducing the size of the outlet.

  • Publication number: 20080255594
    Abstract: The invention relates to a novel medical apparatus for treatment of obesity, diabetes, and/or other obesity-associated health problems. The apparatus is used to impede absorption of nutrients within the gastrointestinal tract, i.e., substantially isolating nutrients from a portion of the gastrointestinal tract. The apparatus can be implanted using minimally invasive techniques, such a transesophageal approach under visualization. More specifically, the apparatus is used to impede absorption of nutrients within the gastrointestinal tract, i.e., substantially isolating nutrients from a portion of the gastrointestinal tract. The apparatus may include a sleeve and at least one anchoring component attached to the sleeve with a releasable component. The sleeve may have different properties along its length or there may be multiple sleeves having different properties.

  • Publication number: 20080250340
    Abstract: An implantable restriction device can be configured to provide a restriction in a patient, for example as a function of the pressure of fluid. The implantable restriction device can include one or more sensors configured to sense a variety of parameters, such as pressure of the fluid within the implantable restriction device, pulse width, pulse amplitude, pulse count, pulse duration, or frequency, electrical characteristics, or other parameters. Data obtained by the one or more sensors (for example, the data representing pressure, pulse characteristics, and so on) may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the data, and may communicate the data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger.
