ACCESS PORT INDICATOR FOR IMPLANTABLE MEDICAL DEVICE
First Claim
1. An implantable medical device adapted for placement under the skin of a subject, comprising:
- a. a housing defining a port through which fluid access to the implantable medical device is obtained;
b. a septum incorporated into said housing and positioned in sealing relation to said port;
c. at least one light emitter adapted for emitting light of a predetermined intensity that is directly viewable through the skin of the subject and is positioned in at least partially surrounding relation to said septum, whereby said at least one light emitter non-invasively defines the position of said septum; and
d. circuitry for activating said at least one light emitter.

Abstract
The invention is directed to an implantable pump. The implantable pump has a port with light emitters indicating the location of the port. The port can be useful in providing bolus injections or the refilling of reservoirs. The light emitters can be arranged in various forms about the port including linear, triangular, square, or circular, among others. If more than one port is located on a device, these ports can be differentiated by differing colors and arrangements of emitters. In addition, various circuitries can be used to activate the emitters. These circuitries can include a coil and capacitor arrangement that provide a separate power source from that of the pump.
