Apparatus for adjustment and sensing of gastric band pressure
First Claim
1. An apparatus for communicating fluid, the apparatus comprising:
- (a) a housing, wherein the housing defines an interior portion contained therein, wherein the interior portion is positioned entirely within the housing;
(b) a fluid reservoir positioned within the interior portion of the housing, wherein the fluid reservoir is operable to hold a volume of fluid therein;
(c) an actuator operationally engaged with the fluid reservoir, wherein the actuator is operable to effect communication of fluid from or into the fluid reservoir, wherein the actuator is positioned within the interior portion of the housing such that the actuator is confined within the interior portion;
(d) a sensor in fluid communication with the fluid reservoir, wherein the sensor is operable to sense a physical parameter of fluid that is in communication with the fluid reservoir as the fluid is communicated from or into the fluid reservoir; and
(e) an indicator in communication with the sensor, wherein the indicator is operable to display the physical parameter sensed by the sensor.

Abstract
An apparatus is operable to communicate fluid. An exemplary apparatus comprises a housing and a fluid reservoir within the housing. An actuator is operationally engaged with the fluid reservoir. The actuator is operable to effect communication of fluid from or into the fluid reservoir. A sensor is in fluid communication with the fluid reservoir. The sensor is operable to sense a physical parameter of fluid that is in communication with the fluid reservoir as the fluid is communicated from or into the fluid reservoir. An indicator is in communication with the sensor. The indicator is operable to display the physical parameter sensed by the sensor. The apparatus may be used to inject fluid into or withdraw fluid from an implanted gastric band system or for a variety of other uses. Fluid pressure may be adjusted and sensed, and resulting data may be displayed, by a single, integrated instrument.

15. An apparatus for communicating fluid, the apparatus comprising:
-
(a) a housing defining a syringe receiving portion and a handle portion, wherein the syringe receiving portion is configured to receive a syringe barrel and a syringe plunger; (b) an actuator mechanism, wherein the actuator mechanism comprises a stem feature, wherein the actuator mechanism is configured to engage with a syringe plunger received by the housing such that the stem feature is coaxially aligned with the syringe plunger, wherein the stem feature is movable from a first proximal position to a second distal position, wherein the stem feature of the actuator mechanism is operable to distally urge a syringe plunger within a syringe barrel, when the syringe barrel and syringe plunger are received by the syringe receiving portion, by moving the stem feature from the first proximal position to the second distal position, wherein the stem feature of the actuator mechanism is operable to proximally urge the syringe plunger within the syringe barrel, when the syringe barrel and syringe plunger are received by the syringe receiving portion, by moving the stem feature from the second distal position to the first proximal position; (c) a sensor fixed relative to the housing, wherein the sensor is operable to sense a physical parameter associated with the communication of fluid from or into the syringe barrel; and (d) a display in communication with the sensor, wherein the display is operable to display data based on the physical parameter sensed by the sensor. - View Dependent Claims (16, 17)

18. An apparatus for communicating fluid, the apparatus comprising:
-
(a) a housing; (b) a first member and an opposingly facing second member, wherein the first member and the second member are contained within the housing, wherein the second member is configured to axially advance toward the first member; (c) a fluid reservoir within the housing, wherein the fluid reservoir has a variable volume, wherein the fluid reservoir is held between a first plane and a second plane, wherein the first plane is defined by the first member and the second plane is defined by the second member, wherein the fluid reservoir is in communication with the first member, wherein the fluid reservoir is in further communication with the second member; (d) a reservoir engagement mechanism engaged with the fluid reservoir, wherein the reservoir engagement mechanism is operable to selectively vary the volume of the fluid reservoir to expel fluid from or withdraw fluid into the fluid reservoir by compressing or expanding the fluid reservoir between the first member and the second member, respectively; (e) a sensor operable to sense a physical parameter associated with the communication of fluid from or into the fluid reservoir; and (f) a display in communication with the sensor, wherein the display is operable to render data associated with the physical parameter sensed by the sensor. - View Dependent Claims (19, 20)
