ABSTRACT:
A novel catheter apparatus for use in delivering an anesthetic agent or other fluid medicament to the portion of subcutaneous tissue through which a catheter device has been inserted into a patient, thereby allowing the catheter device to be retracted without causing pain or discomfort to the patient. The catheter device has an indwelling cannula adapted for insertion through subcutaneous tissue into a patient's body. A helical sheath is formed from an elongate band that is wrapped around the cannula in a helical fashion so as to be capable of being positioned within the subcutaneous tissue once the cannula has been inserted into the body. The helical sheath has formed therein a lumen into which the anesthetic agent or other fluid medicament can be delivered via a hub that is connected to the proximal end of the helical sheath. The helical sheath has formed therein a plurality of delivery holes that form a fluid communication path with the lumen. The delivery holes permit the anesthetic agent or fluid medicament to be delivered to the surrounding subcutaneous tissue.
