Directionless (orientation independent) needle injection port
First Claim
1. An injection port for the treatment of obesity or obesity-related diseases, the injection port implantable in a patient'"'"'s body and fluidly coupled to tubing connected to an inflatable portion of a gastric band, the injection port comprising:
- an inner core made of a material to prevent a needle from penetrating the inner core;
an outer shell surrounding the inner core, and having a lower durometer than the inner core; and
a fluid conduit formed between the inner core and the outer shell, wherein the outer shell is configured to allow penetration by the needle from any location on a surface of the outer shell and at any angle into the fluid conduit to inject fluid to or remove the fluid from the inflatable portion of the gastric band.

Abstract
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.

20. An implantable gastric banding system for the treatment of obesity or obesity-related diseases, the gastric banding system disposed within a patient'"'"'s body, the gastric banding system comprising:
-
a gastric band having a ring and an inflatable portion, the inflatable portion of the gastric band for constricting an upper stomach of the patient; a tubing fluidly coupled to the inflatable portion of the gastric band; and an injection port fluidly coupled to the tubing and the inflatable portion of the gastric band, the injection port including; an olive-shaped inner core composed of a plastic configured to prevent a needle from penetrating the inner core, an olive-shaped outer shell surrounding the inner core, and having a lower durometer than the inner core, the outer shell configured to allow penetration by the needle from any location on a surface of the outer shell and at any angle, and a fluid conduit formed between the inner core and the outer shell, the fluid conduit accessible by the needle to inject fluid to or remove the fluid from the injection port of the gastric band, the fluid conduit fluidly coupled to the inflatable portion of the gastric band via the tubing.
