    Abstract: Each of various modifications of an integrated-structure inflatable balloon catheter design includes a longitudinal structure having a sharply-pointed insertion needle at a distal end of the longitudinal structure and an inflatable balloon situated intermediate a proximate end and the distal end of the longitudinal structure which is attached to said longitudinal structure. With the inflatable balloon in a deflated state, the insertion needle may be used to puncture the patient's skin and underlying sub-cutaneous tissue and place the deflated balloon in proximity to the diseased sub-cutaneous tissue, The balloon is then inflated to press against and thereby spatially deform the diseased sub-cutaneous tissue, after which the deformed diseased sub-cutaneous tissue may be therapeutically heated. This heating may be sufficient to cause the creation of a permanent cavity in the deformed diseased sub-cutaneous tissue which persists after the catheter is withdrawn. This permits any selected one of various therapeutic substances to be introduced into this a permanent cavity. One modification employs a balloon having a selected non-uniform, odd pattern shape which, when inflated, cooperates with the shape of the diseased sub-cutaneous tissue. This one modification also may be beneficially used in prostate-treating balloon catheters, which do not have a sharply-pointed insertion needle at the distal end thereof.

    Abstract: A tissue ablation device includes a catheter shaft having an antenna lumen, an impedance-matched microwave antenna carried in the antenna lumen of the catheter shaft, at least one cooling lumen in the catheter shaft around the antenna lumen for circulation of cooling fluid, and a microwave generator operatively coupled to the antenna for energizing the antenna to create a lesion in the targeted tissue around the catheter shaft having a controlled location and size. In an exemplary embodiment, a tip is attached to an end of the catheter shaft for penetrating the tissue targeted for treatment. The device is effective for laparascopic or percutaneous procedures to treat tissues such as the kidney.

    Abstract: A modular biopsy, ablation and track coagulation needle apparatus is disclosed that allows the biopsy needle to be inserted into the delivery needle and removed when not needed, and that allows an inner ablation needle to be introduced and coaxially engaged with the delivery needle to more effectively biopsy a tumor, ablate it and coagulate the track through ablation while reducing blood loss and track seeding. The ablation needle and biopsy needle are adapted to in situ assembly with the delivery needle. In a preferred embodiment, the ablation needle, when engaged with the delivery needle forms a coaxial connector adapted to electrically couple to an ablating source. Methods for biopsying and ablating tumors using the device and coagulating the track upon device removal are also provided.

    Abstract: A method and apparatus for reducing restenosis of a stenotic region of a blood vessel after performing a dilatation angioplasty treatment is disclosed. The method includes radiating microwave energy from a microwave antenna to kill a medial tissue layer of the blood vessel in the stenotic region. The radiation is applied during or after inflation of dilatation balloon to permanently dilate the stenotic region. When radiation is applied during dilatation of the stenotic region, the dilatation balloon forms a seal against the inner wall surface of the blood vessel to exclude blood in the vessel from contacting the stenotic region. The method preferably further includes cooling the blood circulating in the blood vessel about a shaft of the catheter with cooling fluid circulating within cooling lumens of the catheter and cooling an inner wall surface of the blood vessel in the stenotic region during the application of radiation to the medial cell layer. Finally, the method also preferably includes perfusing blood in the vessel through the catheter across the stenotic region during dilatation of the stenotic region to maintain circulation of blood through the blood vessel during the dilatation of the stenotic region.
