Abstract:
A vascular access kit comprising:a vascular access device comprising:an elongated implant body having a wall and first and second ends, said first end defining an insertion end and being sufficiently pointed to ease insertion of said implant body through an incision formed in a patient to a location remote from the incision, at least one access chamber formed therein for receiving medical treatment, a first opening provided in said first end in communication with said access chamber, and a second opening provided in said wall, said second opening in communication with said access chamber;a tubular member having at least one lumen extending therethrough, said tubular member connected to said first end of said elongated implant body, said lumen of said tubular member in fluid communication with said access chamber through said first opening for delivering the medical treatment from said access chamber to a preselected location in the patient remote from the incision;a membrane sealing said second opening, said membrane adapted to receive a percutaneous needle puncture without leakage from the puncture;a dilator comprising:a handle portion and a shaft, said shaft having a distal end portion and a proximate end portion, said proximate end portion disposed toward said handle portion and having an enlarged cross-section dimensioned and adapted to form a passage in the patient which accommodates said elongated implant body of said vascular access device, said handle portion and said shaft including coextensive passageways defining a guide lumen extending from said handle to said distal end of said shaft for receiving a guide wire therethrough, said distal end portion adapted for inserting a sheath into an opening in the patient; anda sheath comprising:a tubular sheath body including a first end and a second end, said first end of said tubular sheath body having a first diameter and adapted for inserting into an incision in the patient, said second end of said tubular sheath body having a second diameter and defining an entrance, said second end of said tubular sheath body dimensioned and adapted to receive said enlarged proximate end portion of said dilator, said tubular sheath body being formed of flexible material and being adapted to tear along a longitudinal path extending between said first and second ends of said tubular sheath body; andpull members disposed on said second end at opposed sides of said entrance for pulling and splitting said tubular sheath body along said longitudinal path.
