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 device, such as an infuser device for bidirectional hydraulically controlling a medical artificial sphincter, enhances power transfer characteristics to a secondary coil thereby allowing implantation to greater physical depths and/or enclosing the secondary coil within a housing of the infuser device. The enhanced power transfer is achieved with multiple coils that are longitudinally aligned and physical and electrical parallel to form the secondary loop of a transcutaneous energy transfer system (TET) instead of a single coil. It better optimizes the power transfer from a parallel tuned tank circuit primary coil to an implanted secondary series tuned tank circuit coil.

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： The present invention pertains generally to a liquid control assembly wherein the assembly is useful in the placement of liquid dispersed at an angle, and more particularly, a nozzle assembly for directing thermal melt adhesive at an angle onto a desired target. The nozzle assembly includes a nozzle projection that exhibits a minimized effective radius and as such minimizes the temperature drop of the nozzle assembly with respect to the thermal melt extrusion head to which it is attached, thus retaining an operating temperature suitable for extrusion of thermal melt adhesives. The nozzle assembly further includes a two part inter-locking construction that allows for free axial rotation of the nozzle projection while retaining simplified assembly, maintenance, repair, and installation when used in conjunction with a thermal melt extrusion assembly.

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 method for aiding a surgical procedure, the method uses the steps of providing a surgical instrument with an elongated shaft having a distal end, a proximal end and a longitudinal axis therebetween, the distal end having an end effector attached thereto, the shaft having a first strip running along the longitudinal axis and attached to the end effector, and a second strip, parallel to the first strip, running along the longitudinal axis from the distal end of the shaft to the distal end of the end effector where it is attached thereto, the end effector comprising a plurality of spaced apart links disposed along the longitudinal axis between the distal end of the end effector the distal end of the shaft such that the strips run through the links, and each link is attached to at least one strip. The method also includes the steps of inserting the instrument to a desired location in a body and curving the instrument by moving the first strip proximally. The method also includes the steps of preventing the first strip from moving proximally beyond a predetermined amount and thereby causing the end effector to bend only up to a predetermined angle, and preventing the links from making contact with one another.

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.
