摘要： Adjustable gastric band implants contain a hollow elastomeric balloon with fixed end points encircling a patient's stomach just inferior to the esophago-gastric junction. These balloons can expand and contract through the introduction of saline solution into the balloon. In current bands, this saline solution must be injected into a subcutaneous port with a needle to reach the port located below the skin surface. The port communicates hydraulically with the band via a catheter. As an alternative to using a percutaneously accessed injection port, a system for regulating the flow of saline that is totally implanted may rely upon bi-directionally pumping fluid from an implant device. This system instead transfers AC magnetic flux energy from an external primary coil to a secondary coil that powers the pump in the implanted reservoir. A magnetically permeable rod centered within the primary coil increases power coupled to the secondary coil.

摘要： An implantable artificial sphincter system provides long-term adjustment via transcutaneous energy transfer (TET), minimizing invasive adjustment through adding or removing fluid via a syringe. An infuser device provides bi-directional fluid transfer via a flexible conduit to a sphincter band, such as a gastric band, by a combination of thermodynamic actuation and a piezo-electrically disengaged drum brake assembly that thereby achieves a desirable small volume device. A propellant within a propellant cavity surrounds a metal bellows accumulator biased at body temperature to either expand or collapse the bellows accumulator with the opposite direction of movement effected by a thermal element that heats in combination with a negatively-biased propellant or cools in combination with a positively-biased propellant. A drum brake assembly locks the metal bellows accumulator in place between adjustments by thermodynamic actuation by activating piezo-electric stack actuators that disengage calipers from a brake drum attached to the bellows accumulator.

摘要： An actuator having a variable internal volume is mechanically coupled to an adjustable implantable band so as to effect changes in the effective internal perimeter of the band. The actuator may be directly connected to the band, or be connected through a cable. Configurations of the actuator include a series of folds and ridges and bellows. A plurality of actuators may be used in combination with a single band. A clutch mechanism may be included to hold the band in place when not acted upon by the actuators. One end of the actuator may be connected directly to a bidirectional flow device.

摘要： A remotely controlled gastric band system that is practically immune to external magnetic fields, such as from a Magnetic Resonance Imaging (MRI) machine, incorporates a bi-directional pump and fluid reservoir to adjust fluid volume for hydraulic control of a gastric band. A piezoelectric driver (e.g., rotary actuator, linear actuator) selectively compresses and expands a metal bellows hermetically sealed within a biocompatible and nonferromagnetic enclosure or case such as titanium. Directly sensing a position of the metal bellows yields an accurate reading of volume contained therein, allowing for closed-loop control of the gastric band.

摘要： An implantable medical device system advantageously utilizes low frequency (e.g., about 1-100 kHz) transcutaneous energy transfer (TET) for supplying power from an external control module to an implantable medical device, avoiding power dissipation through eddy currents in a metallic case of an implant and/or in human tissue, thereby enabling smaller implants using a metallic case such as titanium and/or allowing TET signals of greater strength thereby allowing placement more deeply within a patient without excessive power transfer inefficiencies.

摘要： An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors 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 pressure data, and may communicate the pressure 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.

摘要： An implantable adjustable sphincter system is comprised of a band configured to encircle a portion of an anatomical passageway, a manual pump, a reservoir in fluid communication with the pump, and a valve assembly in fluid communication with the band and the manual pump. The valve assembly is comprised of a first configuration and a second configuration, and is operable to be manually switched between configurations. The first configuration only permits fluid to flow from the band toward the reservoir. The second configuration only permits fluid to flow from the reservoir toward the band. The manual pump is in fluid communication with the valve assembly and the reservoir, and is manually operable to transfer fluid between the reservoir and the band when the valve assembly is in the second configuration.
