ABSTRACT:
A device for installing a catheter in a patient's body for use in delivery of a radioactive source to and from the site of a tumor so that it may be shrunk. The device includes a catheter and apparatus for implanting the catheter through the tumor site so that the distal end of the catheter extends beyond the site, with the proximal end exposed externally of the body to permit entry and withdrawal of the radioactive source. A selectively deployable anchor at the distal end of the catheter is adapted to penetrate body tissue at the distal end beyond the tumor site when the anchor is deployed. Consequently, the distal end of the catheter will be securely anchored to maintain a substantially constant lineal depth from the proximal end of the catheter to the tumor site. The radioactive source can then be driven through the catheter to the tumor site to irradiate the tumor for a prescribed period, and then withdrawn. The patient remains ambulatory with the catheter in place between fractionated periodic treatments, and yet repetitive radiation treatment consistently at the precise desired location is assured.
