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： 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.

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.

摘要： A sense head comprises a plurality of coils and a needle window. The sense head is operable to receive RF signals communicated from a needle target such as an injection port located within a patient. A user interface is configured to visually display an indication to a user relating to the positioning and orientation of the sense head relative to the needle target. The positioning and orientation may be determined based on RF signals received by the coils in the sense head. With the sense head positioned based on information provided through the visual display, the user may insert a needle through the needle window to reach the needle target. The sense head may also receive communications relating to the pressure of fluid in an implanted device. The user interface may further display information relating to the fluid pressure in the implanted device.

摘要： An implantable medical device, such as a bi-directional infuser device for hydraulically controlling an artificial sphincter (e.g., adjustable gastric band) benefits from being remotely powered by transcutaneous energy transfer (TET), obviating the need for batteries. In order for active components in the medical device to operate, a sinusoidal power signal received by a secondary coil is rectified and filtered. An amount of power transferred is modulated. In one version, a voltage comparison is made of a resulting power supply voltage as referenced to a threshold to control pulse width modulation (PWM) of the received sinusoidal power signal, achieving voltage regulation. Versions incorporate detuning or uncoupling of the secondary coil to achieve PWM control without causing excessive heating of the medical device.

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.
