Implantable access port system

摘要

An implantable injection port comprises a base. A first gear is coupled to the base, and a first anchor is coupled to the first gear. A second gear is coupled to the base, and a second anchor is coupled to the second gear. A top portion of the injection port is spaced apart from the base of the port and has a first plurality of top teeth that engage with a first plurality of gear teeth on the first gear. This engagement occurs prior to rotation of the second gear. The top portion rotates, which causes rotation of the first gear, which in turn causes movement of the first anchor through the anchor opening of the base and into the tissue of the patient. The first gear and the second gear rotate non-simultaneously.

1. An implantable injection port for use with a gastric band for treating obesity and for attaching to a tissue of a patient, the implantable injection port comprising:
a base having a first anchor opening; a first gear coupled to the base and rotatable about a first axis, the first gear having a first plurality of gear teeth; a second gear coupled to the base and rotatable about a second axis, the second gear having a second plurality of gear teeth; a first anchor coupled to the first gear; a second anchor coupled to the second gear; and a top portion spaced apart from the base and having a first plurality of top teeth that engage with the first plurality of gear teeth on the first gear prior to rotation of the second gear, the top portion being rotatable causing rotation of the first gear such that the rotation of the first gear causes movement of the first anchor through the anchor opening of the base and into the tissue of the patient, wherein subsequent to the first plurality of top teeth rotating a predetermined amount with the first plurality of gear teeth on the first gear, the first plurality of top teeth are configured to begin to rotate with the second plurality of gear teeth on the second gear and cause rotation of the second gear to begin subsequent to a beginning rotation of the first gear, which causes movement of the second anchor through a second anchor opening of the base and into the tissue of the patient.
