摘要： A venous access port assembly having a housing base with a discharge port, a septum and a cap. An interior reservoir is defined by a well in the housing base and a bottom of the septum, and a passageway extends from the reservoir through the discharge port. The housing base includes a base flange having integrally molded therein indicia identifying an attribute of the assembly. The indicia could be formed of base flange material, or could be formed by voids in the base flange material. If of plastic material, the molded indicia could be applied with a radiopaque agent, thereby allowing the indicia (“CT”) to appear on an X-ray of the patient in a manner informing a practitioner of a particular attribute of the assembly.

The assembly also includes a guidewire straightener (10,210,410) having a distal end (12,212,412), a proximal end (14,214,414) having an exterior surface with a diameter sized to fit within the guidewire tube, and a longitudinal passageway (18,218,418) therethrough sized to accept the guidewire (52,202,402). The proximal end of the guidewire straightener further includes a biasing member (20,220,420) with at least one finger (26,216,416) therealong. The assembly further includes a guidewire (52,202,402) disposed within the tubular passage and the longitudinal passageway(18,218,418). When the guidewire straightener (10,210,410) is disposed within the guidewire tube in a first position with its biasing member in the tubular passage, the at least one finger (26,216,416) is biased by the tubular passage into frictional engagement with the guidewire; when disposed in a second position, the at least one finger is disposed away from frictional engagement with the guidewire.

摘要： An adapter assembly (120) for connecting a catheter assembly (50,52) to a tunneler (110) having a generally tubular body (122) having a first end (124), a second end (126) and a longitudinal axis (128) extending therethrough between the first end and the second end. The first end (124) of the adapter is constructed to engage the proximal end (114) of a trocar (110). The second end (126) of the adapter is constructed to releasably engage at least one catheter lumen (50,52). A slider (140) is disposed about the adapter (120) and is longitudinally slidable along the adapter. When the slider (140) is slid towards the second end (126) of the adapter, the slider engages a plurality of legs (134a-134d) on the adapter and biases the plurality of legs toward each other and the longitudinal axis of the adapter. A method of subcutaneously tunneling a catheter using the adapter assembly is also described that comprises inserting a catheter into a patient, connecting the proximal end of a trocar to the adapter assembly, releasably restraining at least one lumen of the catheter in the adapter, and tunneling the assembly.
