    摘要: An external pressure sensing system may include an attachment for a syringe. The attachment may comprise a connector positioned between the barrel and the needle of the syringe. A pressure sensor may be in fluid communication with the connector, such that the pressure sensor may sense the pressure of fluid within the connector as the syringe is used to add fluid to or withdraw fluid from an injection port. Where an injection port is a component of an adjustable fluid-based gastric band system, pressure data obtained with the pressure sensor may be indicative of the pressure of fluid within the gastric band. The pressure sensor may communicate pressure data to a display device. A user may adjust the pressure of fluid within the gastric band using the syringe while viewing the display device for pressure-related readings.

    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, which may process the pressure data, and may further provide a display to a user including information relating to the processed pressure data. Where the implantable restriction device comprises an adjustable gastric band, the one or more pressure sensors may be located in any number of the following locations: an injection port, an interface between the injection port and a catheter, in a catheter, in-line with a catheter, adjacent to a catheter, in a gastric band, in a gastric band buckle, or elsewhere.

    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 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.
