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 (10) 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 (18). A piezoelectric driver (60) (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 (38) yields an accurate reading of volume contained therein, allowing for closed-loop control of the gastric band.

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 (10) provides long-term adjustment via transcutaneous energy transfer (TET), minimizing invasive adjustment through adding or removing fluid via a syringe. An infuser device (30) provides bi-directional fluid transfer via a flexible conduit (28) to a sphincter band (14), such as a gastric band. Materials are nonferrous and nonmagnetic so as to be magnetic resonance imaging (MRI) safe, being substantially immune to strong magnetic fields and not introducing an electromagnetic interference/compatibility (EMIC) hazard.

摘要： An implantable artificial sphincter system (10) provides long-term adjustment via transcutaneous energy transfer (TET), minimizing invasive adjustment through adding or removing fluid via a syringe. An infuser device (40) provides bi-directional fluid transfer via a flexible conduit (42) to a sphincter band, such as a gastric band (30), by a combination of thermodynamic actuation and a piezo-electrically disengaged drum brake assembly (200) that thereby achieves a desirable small volume device. A propellant within a propellant cavity (136) surrounds a metal bellows accumulator (70) biased at body temperature to either expand or collapse the bellows accumulator with the opposite direction of movement effected by a thermal element (150) that heats in combination with a negatively-biased propellant or cools in combination with a positively-biased propellant. A drum brake assembly (200) locks the metal bellows accumulator (70) in place between adjustments by thermodynamic actuation by activating piezo-electric stack actuators (216, 218) that disengage calipers from a brake drum attached to the bellows accumulator.

摘要： A restriction system (10) is provided and includes a first housing having a reservoir formed therein and configured to receive fluid, and a second housing spaced apart from and in fluid communication with the first housing. The second housing can have a sensor, for example, for measuring fluid pressure. A restriction device can be in fluid communication with the first and second housings and can be adapted to form a restriction in a pathway. A constraining element can be coupled to the first and second housings and can be configured to limit movement of the first and second housings relative to one another in at least one plane of motion.
