Onlay subcutaneous injection port

摘要

The device is an implantable subcutaneous injection port used for various purposes including, but not limited to, vascular access and laparoscopic adjustable gastric banding. This device, with its tubing route and flexible connectors offers a solution to the problem of tubing occlusion and loss of integrity due to kinking. This device exhibits an injection chamber disposed within a housing. A self sealing septum is disposed within an injection chamber aperture. A second aperture communicates with a tube that is designed to connect to a catheter or other device suitable to the surgical application. Here the second aperture exits directly beneath the onlay port reducing the possibility of tubing kink, needle puncture and malpositioning seen with only ports where the catheter exits from the side of the device. An alternate embodiment utilizes a u-joint and ball joint to maximize the flexibility of the connection between the onlay port and the exiting catheter.

主权项

1. An onlay access port comprising:
a. an injection chamber housing having a first housing aperture and an opposing second housing aperture, b. an injection chamber disposed within said injection chamber housing, having a first chamber aperture and an opposing second chamber aperture, c. a self sealing septum sealably disposed within said second chamber aperture, d. a catheter seat in fluid communication with said first chamber aperture, e. a catheter having a first catheter end and a second catheter end, said second catheter end in fluid communication with said catheter seat, said catheter extending through said first housing aperture parallel with the longitudinal axis of said onlay port.
