| titleOfInvention | Implantable infusion device |
| abstract | An infusion port (10) for implantation adapted for providing repeated access to specific tissue within a patient and communicating with the tissue by an internal implanted catheter (52). The infusion ports according to this invention incorporate an enlarged entrance orifice (13) with a funnel shaped internal cavity which narrows down to a reduced diameter passageway (18). An articulating catheter valve (24) is provided within the passageway which normally prevents the flow of fluids through the valve but can be penetrated by an external introduced filament (32) such as a catheter. After implantation, an external filament (32) which is introduced into the port (10) is guided by the port internal cavity into registry with the catheter valve (24). Continued feeding of the filament (32) causes the catheter to pass through the valve (24). Thereafter, when a catheter (32) is inserted, therapeutic agents infused within the patient, or body fluids can be withdrawn. Alternate embodiments disclose various valve concepts (56) and means for providing a change in direction of an introduced filament inserted through the infusion device. Additional embodiments disclose the concepts of providing an antimicrobial fluid bath (98) within the device for prevention of infection and various approaches for securely connecting an internal catheter (52) to an infusion port. |
