Implantable access devices
First Claim
1. A method of providing repeated access to a preselected site within a patient by an external filament comprising the steps of:
- providing an access port having a housing including an entrance orifice, an exit orifice and a passageway connecting the entrance orifice to the exit orifice,providing a catheter,making an incision in the patient'"'"'s skin,locating the site within the patient through the incision,affixing one end of the catheter to the site,affixing an opposite end of said catheter to the access port exit orifice,inserting the access port through the incision to a subcutaneous position, and closing the incision.

Abstract
An access port for implantation within the body of a patient for providing repeated access to a specific site within the patient and communicating with the site by an implanted internal catheter. The access ports in accordance with this invention include a housing having an inlet orifice leading to a reduced diameter guide passageway. An external filament such as a needle, guide wire, optical fiber, or external catheter can be introduced into the access device and fed through the housing. The system allows the introduction of therapeutic agents, the removal of fluids from the body, or the introduction of sensing or articulating devices to the specific site within the patient.
