    Abstract: A catheterization guidewire system provides a first wire for percutaneous insertion in a blood vessel. The first wire may include a lumen running from one end to the other, and a handle adjacent the proximal end for manipulation of the first wire about and along a central axis. A second wire may be inserted in the blood vessel over the first wire, and may have a handle adjacent a proximal end. With the first and second wires coupled together, either of the handles of the first and second wires may be used to manipulate both wires. The wires may be manipulated relative to one another by simultaneous use of both handles. The first wire may have a rigidity selected to allow crossing of a bifurcation in the blood vessel. A third wire, which may also have a handle, may be inserted in the blood vessel over the second wire. A catheter for insertion over at least one of the first, second, and third wires may be provided with a balloon and a stent placement apparatus.

    Abstract: A trifurcated stent apparatus for use by a physician includes a main stent for inserting into a trifurcated blood vessel and two side stents. The main stent includes two openings on the side which are the same diameter as the corresponding side stents. The main stent may be configured to receive a first end of a first side stent and a first end of a second side stent, to create a trifurcated stent. Alternatively, the side stents and the main stent may form a single integrated unit. The main stent and side stents can include one-way valves on one or more of the ends. The one or more one-way valves may be opened or closed, depending on whether the physician desires that fluid pass through. While closed, the valve may be configured to allow passage of various cardiovascular instruments, including but not limited to guidewires, catheters, balloons, or any other device used in blood vessel operations, while not allowing the passage of any fluids.

    Abstract: A small-diameter surgical snare device that is capable of fitting through existing balloon or guiding catheters includes metal tubing along a section of a core wire. The distal end of the core wire connects to one or more snare wires that form the snaring loop. The distal end of the snaring loop supports a radiopaque coil or collar that makes the end of the loop visible under fluoroscopy. The snaring loop may consist of one or two wires or an overlap of a tapered end of the core wire. A radiopaque coil is attached to a distal end of the metal tubing, to provide flexibility and visibility to a distal region of the device. Alternatively, a polyimide tube and a short radiopaque marker may be included at a distal end of the metal tubing. The polyimide tube fits inside of the metal tubing, to add strength and torsion control to the distal region of the device, while the radiopaque marker adds visibility. In all embodiments, a shrink tube is fit over the radiopaque coil or marker that is supported by the distal end of the metal tubing, to ensure that the coil does not stretch when the snaring loop is extended during use.

    Abstract: Methods for treating bodily tissues and fluid vessels are disclosed. According to a method of repairing a perforation in a bodily fluid vessel, a viscous, moldable substance is inserted into the vessel at the location of the perforation. A path is opened through the moldable substance to permit fluid flow through the vessel. According to a method of introducing a tissue-killing substance into a bodily fluid vessel, a catheter is provided that has a blocking mechanism configured to selectively block and unblock the vessel. The catheter also has a delivery system that is configured to introduce the tissue-killing substance into the vessel. The vessel is substantially blocked upstream of a selected tissue using the blocking mechanism. The tissue-killing substance is introduced into the vessel through the delivery system, and the vessel is unblocked when the tissue-killing substance has substantially traveled toward the selected tissue. According to a method of occluding a bodily fluid vessel, a catheter is provided that has a first passage. The first passage has an occlusion element housed therein. The catheter is positioned in the vessel, and the occlusion element is moved out of the passage and into the vessel to thereby occlude the vessel. A catheter is also disclosed that may be used with the above methods.

    Abstract: A system and method for treating a stenosis or blockage in a bodily fluid passageway is described. The system includes a catheter and a controller for generating radio frequency energy along a pair of output lines, a monitoring circuit for monitoring the phase of the radio frequency energy along the output lines, and an impedance matching circuit for adjusting the output impedance of the generator so that it equals that of a load, e.g., the patient. The catheter includes a catheter body which is insertable into the bodily passageway and operatively connected to the controller. A lumen in the catheter body defines an opening and a stainless steel, metallic-plated mandril is disposed within the lumen so that a terminal end thereof extends through the opening and into the bodily passageway. An internal electrode is joined to the terminal end of the mandril, with the other end of the mandril operatively connected to one of the output lines for receiving the radio frequency energy produced by the generator and delivering such energy to the terminal end and the internal electrode. An external electrode in the form of a grounding pad is located externally of a patient so that when the radio frequency energy is delivered via the mandril to the internal electrode, the same causes or enables the capacitative heating of a stenosis. The method of the present invention relates to finding the most optimal position for placement of the catheter so that optimal power may be delivered to the stenosis.

    Abstract: A catheter introducer system is provided with a catheter sheath having a valve providing for a friction fit around a catheter. The friction fit is selectively adjustable to vary between a first configuration for longitudinal movement of the catheter through the valve and a second configuration for holding the catheter longitudinally in place. The valve may include a chuck to grip the catheter radially. The chuck may include an annular base and an opposed annular clamp, and a washer disposed between the base and the clamp. At least one of the base and the clamp may include a beveled surface that forces the washer radially inwardly as the base and the clamp are drawn together. The system also includes one or more dilators layered within the sheath. One or more of the dilators may include a preformed arcuate portion configured to access a targeted branched vessel. The layered dilators and sheaths are typically softer and more hydrophilic proceeding from the innermost dilator out to the sheath. The dilator may be reinforced by a wire embedded in the body of the dilator. The distal tip of the sheath may be stiffened by a ring affixed adjacent the distal end. The sheath may include in the innermost dilator a trocar formed of a flexible, hollow outer wire and an inner stiff needle, which can extend beyond the wire for piercing and be withdrawn to relax the wire for advancement of the dilator.
