    摘要: A fluid delivery catheter that uses micro-needles for fluid delivery though a vessel wall. The catheter may provide fluid delivery therapy for various procedures, such as, for example, delivery of tumescent fluid or renal denervation. The catheter includes an elongate member with deployable and retractable needles disposed about a distal end of the elongate member. The needles may be disposed radially about the distal end and/or along a length of the distal end.

    摘要: A tissue surface reatment apparatus includes a housing having a proximal end, a distal end including a tissue contacting surface, an interior defined by the housing and a handpiece coupled to the housing. The contactine surface has a plurality of apertures. An energy delivery device including an electrode is positionable in the housing interior. The electrode includes a tissue penetrating distal end in substantial alignment with an aperture. The electrode is configured to be advanced from the housing interior through the aperture and into a target tissue site to define an ablation volume at least partly bounded by a tissue surface. An advancement device is coupled to the energy deliveru device and is at least partly positionable within at least one of the housing or the handpiece. The advancement device is configured to advance the electrode fdro the housing interior into the target tissuesite and withdrawal the electrode into the housing interior. A cable is coupled to the housing or the energy delivery device and is configured to be coupled to an energy source.

    摘要: A method of controlling ablation volume depth includes providing a treatment apparatus. The apparatus comprises a housing having a proximal and distal end including a tissue contacting surface. The housing defines an interior with an energy delivery device positionable in the interior. The energy delivery device includes at least one electrode with a tissue penetrating distal end and is configured to be advanced from the interior into a target tissue site to define an ablation volume. An advancement device is coupled to the energy delivery device and is configured to advance the at least one electrode. The at least one electrode is advanced to a selected deployment depth beneath a tissue surface while avoiding a critical structure. Energy is delivered from the energy delivery device. An ablation volume is created at a controlled depth below the tissue surface responsive to the deployment depth while minimizing injury to the critical structure.

    摘要: An apparatus method for establishing a Transjugular Intrahepatic Portosystemic Shunt between the portal vein from a hepatic vein. The apparatus comprises an elongated hollow outer guide; an outer handle having an inner lumen and a first luer lock, the outer handle attached at a proximal end of the outer guide, the outer guide in flow communication with the inner lumen and the luer lock; an elongated hollow inner needle; and a hub having a second luer lock, the hub attached at a proximal end of the inner needle, the inner needle in flow communication with the second luer lock. The inner needle is slidingly received into the outer guide through the inner lumen. The inner needle is configured to rotate within the outer guide by manipulation of the hub; and a distal tip of the inner needle is deployed out of and beyond a distal tip of the outer guide.
