Abstract:
A vascular access device for inserting into a patient body through an incision, the incision having an incision width, said vascular access device adapted to be used for periodic delivery of medical treatment to a preselected location in the patient body remote from the incision, such as delivery of a fluid to a treatment site, said vascular access device comprising:an elongated implant body having a first end, a second end, and at least one access chamber formed therein, said first end including a first opening in communication with said access chamber, said first end defining an insertion end and being sufficiently pointed to separate tissue when said elongated implant body is inserted into the patient body through the incision to a placement location in the patient's body remote from the incision whereby said implant body can be urged to said placement location without the need to excavate tissue in the patient's body, said implant body defining a second opening in communication with said access chamber and tapering to said first and second ends to define a smooth substantially continuous outer surface between said first and second ends to ease insertion of said implant body through the incision and, further, to ease separation of the tissue of the patient's body when urged to said placement location, said elongated implant body having a width and a length, said length greater than said implant body width;a tubular member having at least one lumen extending therethrough, said tubular member connected to said insertion end of said elongated implant body, said lumen in fluid communication with said access chamber through said first opening for delivery of material from said access chamber along said tubular member to the preselected location in the body; anda membrane sealing said elongated implant body second opening, said membrane adapted to receive a percutaneous needle puncture without leakage from the puncture, and said elongated implant body is adapted to be inserted through the incision which incision will accommodate said width of said elongated implant body but is less than said length thereof and further is capable of being urged to the placement location remote from the incision for periodic delivery of fluid treatment to the preselected location remote from the incision and from the placement location.
