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 further manipulated or 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 cylindrical sleeve around the cannula can be positioned within the subcutaneous tissue once the cannula has been inserted into the body. The cylindrical sleeve has formed therein one or more lumens into which the anesthetic agent or other fluid medicament can be delivered via a hub that is connected to the proximal end of the cylindrical sleeve. The cylindrical sleeve has formed therein a plurality of delivery holes that form a fluid communication path with the one or more lumens. The delivery holes permit the anesthetic agent or fluid medicament to be delivered to the surrounding subcutaneous tissue.
