摘要:
Transoral obesity treatment devices and related methods for operation thereof are described which occupy space within a stomach and/or stimulate the stomach wall. The transoral obesity treatment devices and related methods are intended to assist a patient in maintaining a healthy body weight. Features of the devices include insertion transorally and without invasive surgery, without associated patient risks of invasive surgery, and without substantial patient discomfort. The life span of these devices may be material-dependent upon long-term survivability within an acidic stomach, but is intended to last one year or longer. The devices have the capacity to vary in size and are desirably self-actuating in that they change shape and/or volume using internal motors or actuators. The changing character of the devices helps prevent the person's stomach from compensating for the implant, such as sometimes happens with static intragastric devices.

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.

In some embodiments, the present invention generally provides self-adjusting gastric banding systems for the treatment of obesity and obesity related conditions, as well as systems for allowing the automatic self-adjustment of gastric bands when a patient swallows a large bolus. In some embodiments, the present invention generally provides for gastric banding systems having a satiety booster, for example, to increase satiety levels when a patient desires to curb appetite at a particular time. In some embodiments, the present invention may provide for gastric banding systems that allow for both the automatic self-adjustment of gastric bands when a patient swallows a large bolus and an incorporated satiety booster for increasing satiety levels when a patient desires to curb appetite at a particular time.

An implantable device comprises a reservoir for holding a fluid and a sensor positioned between the gastric band and the reservoir. The sensor monitors a parameter of the fluid when filling and draining the inflatable portion of the gastric band. A first flow control device controls a flow of the fluid when filling and draining the inflatable portion of the gastric band. A pumping device moves the fluid into and out of the inflatable portion of the gastric band, and the pumping device is capable of being activated and deactivated using a telemetric signal received from a remote device.

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.

Generally described herein are apparatus, systems and methods related to utilizing a guiding tip to connect two open ends of respective tubes of a gastric banding system. More particularly, one of these tubes may include a barbed element at or near the point of connection which makes it difficult to connect the two tubes as the barbed element may be larger than an opening to receive the barbed element. The guiding tip provides a solution to this problem by acting as an interface between the barbed element and the receiving tube. In this manner, the sealing functionality of the barbed element may be retained while improving the ease of inserting the barbed element into the receiving tube.
摘要:
Generally described herein are certain embodiments directed to an orientation-independent injection port fluidly coupled to a gastric banding system. The injection port may be configured to simplify the port-targeting process when a medical professional attempts to penetrate the injection port with a needle during a gastric band-adjusting procedure. For example, the injection port may be orientation-independent with the entire outer shell acting as the needle access point. Alternatively, and/or in addition, the inner core of the injection port may be hard or firm, thereby allowing for easier locating (e.g., when the medical professional performs palpation). Furthermore, the hard inner core may prevent needle over-throws, and help stabilize pressure.

Generally described herein are automatic, self-adjusting, gastric banding systems and improvements thereof, that are capable of automatically relaxing and contracting in response to a large bolus passing through the area of a patient's stomach constricted by a gastric band. Alternatively, and/or in addition in one or more embodiments, the gastric banding systems described herein may also help prevent pouch dilatation and/or erosion. The apparatus and systems described herein aid in facilitating obesity control and/or treating obesity-related diseases while generally being non-invasive once implanted. Furthermore, certain embodiments of the self-adjusting gastric banding systems disclosed herein are automatically adjustable without complicated fluid control mechanisms, flow rate limiting devices, and/or valves. The automatic adjustments may also be made in response to other changes in the patient's esophageal-gastric junction, for example, in response to size, shape, and or location changes.

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.
