Abstract

The body of a pressure sensing component includes a pressure sensor, a first opening, and a first pair of electrical contacts. A cap of the pressure sensing component comprises a second opening, a wiper seal, and a second pair of electrical contacts. The cap is rotatable relative to the body. When the cap is in a first rotational position, the first and second openings are in fluid communication with each other; and the first pair of contacts are not coupled with the second pair of contacts. When the cap is in a second rotational position, the seal isolates the first opening from the second opening; and the first pair of contacts are coupled with the second pair of contacts. The pressure sensing component may be coupled with a syringe and needle to externally adjust and monitor the pressure of fluid in an implanted gastric band system.

Claims

1. The apparatus, comprising:

(a) a body having a hollow interior portion, wherein the body comprises;

(i) a first opening in communication with the hollow interior portion,

(ii) a pressure sensing device in communication with the hollow interior portion, and

(iii) a first port in communication with the hollow interior portion, wherein the first port is configured to couple with a selected one of a syringe or a needle;

(b) a cap coupled with the body, wherein the cap comprises;

(i) a second opening,

(ii) a seal, wherein the seal is configured to selectively seal the first opening relative to the second opening when the cap is at a first position relative to the body, wherein the seal is further configured to selectively permit fluid communication between the first opening and the second opening when the cap is at a second position relative to the body, and

(iii) a second port in communication with the second opening, wherein the second port is configured to couple with a selected one of a syringe or a needle; and

(c) a communication device coupled with the cap, wherein the communication device is configured to selectively couple with the pressure sensing device when the cap is at the first position, wherein the communication device is further configured to transmit pressure data to an external device when the communication device is coupled with the pressure sensing device.

2. The apparatus of claim 1, wherein the communication device comprises a cable.

3. The apparatus of claim 1, wherein the body comprises a first electrical contact in communication with the pressure sensing device, wherein the cap comprises a second electrical contact in communication with the communication device, wherein the first and second electrical contacts are configured such that the first and second electrical contacts are coupled together when the cap is at the first position, wherein the first and second electrical contacts are configured such that the first and second electrical contacts are not coupled together when the cap is at the second position.
