Abstract: Systems and methods introduce a closure material to seal a vessel puncture site. The system and methods provide a catheter adapted for passage through a tissue puncture and sized to occupy substantially all the tissue puncture. The catheter includes a lumen in fluid communication with a fluid delivery port adjacent the catheter distal end. One or more dispensers are in fluid communication with the catheter lumen for dispensing first and second fluid compositions in the catheter lumen. An actuator causes the first and second fluid compositions to be dispensed from the dispensers and mixed by flowing the first and second fluid compositions through a static mixer. The first and second fluid compositions are dispensed from the fluid delivery port as a fluid mixture that reacts in situ to form a nonfluent closure composition adjacent the vessel puncture site.

Abstract: A device for introducing a catheter into a vessel through a puncture in a vessel and for sealing the puncture. The device includes an elongated body having a proximal end and a distal end sized to be positioned within a tissue site which includes the puncture. The elongated body includes a utility lumen sized to allow a catheter to be delivered through the utility lumen. The utility lumen is positioned within the elongated body so positioning the elongated body within the tissue site allows a catheter delivered through the utility lumen to enter the vessel. The elongated body also includes a closure lumen having an entrance port. A closure composition can be delivered through the entrance port into the closure lumen. The closure lumen also includes an exit port adjacent the distal end of the elongated body. The closure composition delivered into the closure lumen can be delivered through the exit port to the tissue site adjacent the puncture.

Abstract: Methods treat a tissue region. In one arrangement, the methods deploy an endoscope in an esophagus and visualize with the endoscope a Z-line that marks a transition between esophageal tissue and stomach tissue by observing tissue color change at or near the Z-line. The methods deploy an electrode support structure over the endoscope at or near the Z-line visualized by the endoscope, wherein the endoscope serves as a guide for the electrode support structure. The methods introduce from the electrode support structure a tissue-piercing needle electrode into tissue at or near the Z-line and observe introduction of the tissue-piercing needle electrode using the endoscope. The methods couple the tissue-piercing electrode to a source of radio frequency energy to ohmically heat tissue and create a subsurface tissue lesion in tissue at or near the Z-line, and observe creation of the tissue lesion using the endoscope.

Abstract: An ablation apparatus includes an ablation energy source producing an electromagnetic energy output. A multiple antenna device is included, and has a primary antenna with a longitudinal axis, a central lumen and a distal end, and a secondary antenna with a distal end. The secondary antenna is deployed from the primary antenna central lumen in a lateral direction relative to the longitudinal axis. The multiple antenna device is coupled to the ablation energy source.

Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.
