Abstract
An access port assembly having an attachable catheter allows for inserting a guidewire into the catheter to aid in the placement of the integral catheter while still attached to the access port assembly. A method is described for placing an access port fixedly attached to a catheter into a patient using a guidewire inserted into the catheter.
Claims25
An integrated access port assembly comprising in combination:
- a catheter;
- and
- an access port attached to the catheter, the access port including
- a reservoir within the port, said catheter being in continuous, unimpeded fluid communication with said reservoir, and
- multiple sealable entry sites for entry into said reservoir within said port, said multiple entry sites including
- a first entry site comprising a first self sealing septum, and
- at least one second entry site comprising a second self sealing septum aligned opposite said catheter and adapted to accept and permit withdrawal of a guidewire or stylet and direct it into said catheter to thereby facilitate placement of the catheter.
An access port device comprising:
- a body having a self-sealing first access septum disposed in a top portion of the body;
- a reservoir in said body;
- an outlet for fixedly attaching a catheter to the body in continuous, unimpeded fluid communication with said reservoir;
- and
- a self-sealing second septum disposed in the body opposite the outlet for inserting a guidewire through the body and reservoir and into the outlet.
A method for inserting an access port assembly into a patient's body with a guidewire, comprising:
- providing an access port assembly comprising an access port fixedly attached to a catheter, said assembly having a reservoir in continuous, unimpeded fluid communication with said catheter, and at least one entry site on the access port;
- inserting a guidewire into the entry site such that the guidewire extends into the catheter and through both the reservoir and the entry site;
- inserting the guidewire into the patient's body;
- manipulating said assembly over the inserted guidewire to place the distal end of the catheter at the desired location in the patient's body;
- removing the guidewire through said entry site from the assembly and patient's body;
- and
- securing the assembly in the patient's body.
An access port having a body substantially made of a rigid impenetrable material and having an outlet with means for fixedly attaching a catheter in continuous, unimpeded fluid communication with a reservoir disposed within said body, said body having a first entry site comprising a self sealing penetrable septum disposed in the upper portion thereof and a second entry site comprising a closeable port in said body opposite said catheter outlet and substantially in alignment therewith providing outside entry of a guidewire or stylet to said reservoir and said catheter outlet.
An access port device comprising:
- a body;
- a reservoir in said body;
- an outlet for fixedly attaching a catheter to the body in continuous, unimpeded fluid communication with said reservoir;
- and
- a plurality of sealable entry sites disposed in the body for entry into said reservoir, said entry sites including a first self sealing septum and a second self sealing septum, said second septum being adapted to accept and permit withdrawal of a guidewire or stylet and direct it through said reservoir and outlet and into said catheter to thereby facilitate placement of the catheter.
An access port comprising:
- a body;
- a reservoir in the body;
- an outlet for fixedly attaching a catheter to the body in continuous, unimpeded fluid communication with said reservoir;
- multiple sealable entry sites for entry into said reservoir in said body, said multiple entry sites including
- a first entry site comprising a first self sealing septum, and
- at least one second entry site comprising a second self sealing septum aligned opposite said outlet and adapted to permit insertion of a guidewire or stylet and direct it into said reservoir and said outlet.
