  • Patent number: 11944373
    Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system may also include a means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The catheter may also include structures which provide radial and/or lateral support to the guide tubes so that the guide tubes expand uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

  • Patent number: 6471685
    Abstract: A medical dressing assembly and associated method of using the same comprising an isolating member, a member for controllably inputting matter and a member for controllably exhausting matter. The isolating member is capable of isolating an affected area of a patient from an external environment. The isolating member includes a patient engaging strap member and a cover member. The patient engaging strap member includes a bottom surface which is positionable so as to be substantially internally facing. The cover member extends away from the patient engaging member. The cover member defines a volume wherein the patient engaging strap member provides access to the volume. The bottom surface of the at least one patient engaging strap member is capable of engaging a portion of the patient, to, in turn, substantially confine at least a portion of the affected area of a patient within the volume defined by the cover member. The member for controllably inputting matter controllably inputs matter into the volume.
