Stabilization and guide apparatus for access to an implanted access port and related methods
First Claim
1. An insertion device for accessing an access port implanted under the skin of a patient with a needle assembly, the insertion device comprising:
- a body including;
a stabilizing portion that stabilizes a position of the implanted access port when placed on the skin of the patient atop the implanted access port, the stabilizing portion defining an open-ended cavity having an outer perimeter circumscribing a portion of the implanted access port when the insertion device is placed on the skin of the patient atop the implanted access port, a portion of the needle assembly removably disposed in the open-ended cavity; and
a guide portion for guiding a needle of the needle assembly along a predetermined path such that the needle transcutaneously pierces a septum of the implanted access port.

Abstract
An insertion device to assist in accessing an access port that has been subcutaneously implanted in the body of a patient is disclosed. The implanted access port is accessed by a needle of a needle assembly, such as a needle-based infusion set. In one embodiment, the insertion device comprises a body that includes a stabilizing portion and a guide portion. The stabilizing portion stabilizes a position of the implanted access port when the body is placed on the skin of the patient atop the implanted access port. The guide portion guides a needle of the needle assembly along a predetermined path such that the needle transcutaneously pierces a septum of the implanted access port.
