Abstract

A device and method configured for placement into the catheter access port to prevent insertion of a needle into the catheter access port. The device a prong to engage the housing and lock itself in the catheter access port, an annular surface having geometry complimentary to the catheter access port to seal the denial device, and a face configured to deny needle access to the catheter access port. The device is also self sealing to substantial prevent deposition between itself and the catheter access port, is configured to be inserted without the need for tools, and is manufactured from biocompatible material. The method for inserting this device consists of aligning the device with the catheter access port, inserting the device, confirming it is in place, and sealing it into the catheter access port.

Claims

1. An implantable pump comprising:

a housing;

a drug reservoir coupled to the housing, the drug reservoir having a reservoir outlet;

a metering device coupled to the reservoir outlet, the metering device having a metered outlet;

a catheter access port fluidly coupled to the metered outlet, the catheter access port configured for receiving a needle to infuse drug directly into a catheter; and

,

a denial device configured for placement into the catheter access port to prevent insertion of a needle into the catheter access port.

2. The implantable pump as in claim 1 wherein the denial device is self-retaining in the catheter access port.

3. The implantable pump as in claim 1 wherein the denial device is self-sealing to substantially prevent substance deposition between the denial device and the catheter access port.

4. The implantable pump as in claim 1 wherein the denial device is configured to be inserted into the catheter access port without the need for tools.

5. The implantable pump as in claim 1 wherein the denial device is manufactured from a material that is biocompatible.

6. An implantable pump comprising:

a housing;

a drug reservoir coupled to the housing, the drug reservoir having a reservoir outlet;

a metering device coupled to the reservoir outlet, the metering device having a metered

a catheter access port fluidly coupled to the metered outlet, the catheter access port configured for receiving a needle to infuse drug directly into a catheter and,

a means for denial configured for placement into the catheter access port to prevent insertion of a needle into the catheter access port.

7. A denial device for an implantable pump catheter access port, comprising:

a prong configured to engage a catheter access port to lock the denial device in the catheter access port;

an annular surface having a geometry complimentary to the catheter access port to seal the denial device; and

,

a face configured to deny needle access to the catheter access port.

8. A method for inserting a denial device in an implantable pump catheter access port, comprising:

aligning a denial device with a catheter access port;

inserting the denial device into the catheter access port;

confirming the denial device has been fully inserted into the catheter access port; and

,

sealing the denial device in the catheter access port.
