Abstract: A catheter comprises a catheter body with an ablation assembly at its distal end. The ablation assembly has a preformed generally circular curve generally transverse to the axis of the catheter body, and comprises a flexible tubing that carries a tip electrode at its distal end. In use, the generally circular curve contacts the inner circumference of a tubular region of a patient's heart so that the tip electrode contacts tissue along the inner circumference. After ablating the tissue at this first position, the ablation assembly can be rotated so that the tip electrode contacts tissue at a second position along the inner circumference. After ablating the tissue at the second position, the procedure can be repeated to form a lesion of the desired length.

Abstract: A method for fabricating a microfluidic device where first and second substantially flat platens are provided. Multiple substantially planar, substantially metal-free, adhesiveless polymer device layers, the device layers including a first cover layer, second cover layer, and at least one stencil layer defining a microfluidic channel penetrating through the entire thickness of the stencil layer also are provided. Each stencil layer is disposed between other device layers such that the channel is bounded laterally by a stencil layer, and bounded from above and below by surrounding device layers to define an upper channel surface and a lower channel surface. The device layers are stacked between the first platen and the second platen. The stacked device layers are controllably heated according to a heating profile adapted to form a substantially sealed adhesiveless microfluidic device wherein each upper channel surface remains distinct from its corresponding lower channel surface. The resulting microfluidic device has high inter-layer bond strength while preserving the integrity of the channel(s) defined in the stencil layer(s).

Abstract: A dilator having a retractable needle is disclosed. The dilator includes an elongated dilator body having a proximal end, a distal end and at least one lumen longitudinally extending therethrough. A handle is mounted at the proximal end of the dilator body, and a control button is moveably connected to the outside of the handle. The needle extends through the lumen and has a distal end comprising a needle tip section. An arm attached the control button to the needle. Distal movement of the control button causes the needle to move from a retracted position, wherein the needle tip is disposed within the lumen of the dilator body, to a protruding position, wherein the needle tip protrudes beyond the distal end of the dilator body. In use, the distal end of the dilator is inserted into the right atrium of a patient, a position on the atrial septum to be punctured is located with the distal end of the dilator body, the needle tip is advanced beyond the distal end of the dilator body, and the atrial septum is punctured with the needle tip.

Abstract: A catheter particularly useful for ablation lesions within a tubular region of or near the heart is provided. The catheter comprises an elongated flexible tubular catheter body having an axis and proximal and distal ends. An ablation assembly is mounted at the distal end of the tubular body. The ablation assembly has a preformed generally circular curve having an outer surface and being generally transverse to the axis of the catheter body. The ablation assembly comprises a flexible tubing having proximal and distal ends that carries a tip electrode at its distal end. An electrode lead wire extends through the catheter body and into the ablation assembly and has a distal end connected to the tip electrode. In use the distal end of the catheter is interested into the heart of a patient. At least a portion of the outer circumference of the generally circular curve is contacted with the inner circumference of the tubular region so that the tip electrode is in a first position in contact with tissue along the inner circumference. The tip electrode is used to ablate tissue at the first position. The ablation assembly can then be rotated so that the tip electrode is in a second position in contact with tissue along the inner circumference different from the first position, and the tip electrode is used to ablate tissue at the second position. This procedure can be repeated to form a lesion of the desired length along the inner circumference.
