摘要:
An implantable pumping system for pumping a fluid in an implantable gastric banding system comprises a pump for pumping the fluid. A voltage source provides a pump voltage to the system, and a voltage control circuit increases or decreases the pump voltage. A pump driver applies the pump voltage to the pump at a phase and a frequency. The implantable pumping system comprises a sensor that monitors a parameter to facilitate adjusting at least one of the phase or the frequency to maintain a desired value of the parameter. The parameter is associated with at least one of the implantable pumping system or the implantable gastric banding system. A micro controller is configured to manipulate at least one of the phase or the frequency to maintain the desired value of the parameter. The sensor may comprise a temperature sensor, a pressure sensor, and/or a flow rate sensor.

A magnetically coupled, implantable pump system comprises an external controller and an implantable device. A non-implantable magnet in an external controller produces a magnetic field that couples the non-implantable magnet to a magnet in the implantable device. A non-implantable motor moves the non-implantable magnet in a rotational direction. When the non-implantable magnet moves in the rotational direction, a piston coupled to the magnet moves within the implantable device. As the piston moves, an amount of fluid from a reservoir in the implantable device moves out of the reservoir and into an inflatable portion of a gastric band. The implantable device may also move fluid out of the inflatable portion of the gastric band.

A method and system for determining pressure in a syringe, and more specifically to a syringe pressure accessory which can be connected to a syringe to determine pressure in a syringe and a gastric band. The syringe pressure accessory can detect a pressure of a syringe and/or a gastric band and digitally display the pressure. The syringe pressure accessory can include a durable unit and a disposable unit. The disposable unit can be disposed of after a single use, while the durable unit can be reused with multiple disposable units. The syringe pressure accessory can also include a syringe attachment unit and one or more display units for a caretaker or a patient. The display unit can be wirelessly connected to the syringe attachment unit to display a pressure chart or the results of various analysis of the pressure data. Markers can be added to the pressure chart.

An implantable system comprises a housing that includes a flexible reservoir. The flexible reservoir is coupled to an inflatable portion of a gastric band via a fluid inlet/outlet. The flexible reservoir contains a fluid and has an expanded configuration and a contracted configuration. An access port may be coupled to the flexible reservoir and/or the gastric band to facilitate filling and draining the reservoir and/or the gastric band. A movable wall is slidably positioned around the flexible reservoir to move the flexible reservoir between the expanded configuration and the contracted configuration to move the fluid into and out of the inflatable portion of the gastric band. A driving mechanism is positioned around the movable wall and is capable of changing the size of the movable wall to compress or expand the flexible reservoir. A motor, coupled to the driving mechanism, may actuate the driving mechanism.

The present invention is related to a biocompatible and biostable implantable medical device. The present invention can include an implantable medical device including an electro-mechanical component. The electro-mechanical component can be coated with various novel and nonobvious coating combinations designed to promote biocompatibility and biostability. One layer of the coating combinations can be a tie layer. Another layer of the coating combinations can be a layer formed on top of the tie layer, and having biocompatible and biostable properties.

The present invention provides for an access port configured to detect its tilt within the body to facilitate a physician's access thereto. The access port can include a tilt detector to detect tilt datum, and a display screen to display the tilt of the access port. In addition, the tilt detector and the display screen can indicate whether the access port is flipped or not. The tilt detector can include an accelerometer to aid in determining the tilt of the access port.
摘要:
A system and method for determining an adjustment to a gastric band, and more specifically to determining an adjustment to a gastric band based on satiety state data and weight loss data. The gastric band information system can determine an adjustment of the gastric band using a gastric band adjustment algorithm. The gastric band information system can wirelessly transmit the adjustment to the gastric band. The gastric band information system can receive gastric band data, weight data, glucose data, and/or blood pressure data and display a gastric band chart, a weight chart, and/or a blood pressure chart. The gastric band information system can also receive gastric band implantation data, patient data, and/or any other medical data. The various data can be received from a computer or medical devices in a wired or wireless manner.
摘要:
An apparatus comprises a controller for remotely controlling an implantable device that is used to adjust a gastric band, and the controller transmits a telemetric signal to the implantable device. The apparatus further comprises a table that provides support for the controller. A rail is oriented in a first direction with respect to the table, and a tray is slidably coupled to the rail. The tray receives the controller, and the rail moves the tray and the controller in the first direction with respect to the table. The apparatus further comprises a roller coupled to the rail. The roller aids in moving the rail, the tray, and the controller in a second direction with respect to the table. The apparatus further comprises an attachment mechanism for securing the controller to the tray. The apparatus locates the controller in a desired location with respect to a patient.
