Tissue engaging catheter for a radioactive source wire

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 can then driven irradiate prescribed period, withdrawn.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