    摘要： A balloon dilatation catheter for the dilatation of a prostatic urethra having a reinforcing element extending through the elongated shaft of the catheter to prevent significant elongation or failure of the catheter and a traction member for assisting in the resistance to substantial tensile stresses. The balloon dilatation catheter also includes an expandable means between the balloon and catheter shaft to extend the length of the balloon when it is deflated. The extension of the deflated balloon prevents the balloon from bunching up and interfering with the withdrawal of the balloon through the working channel of the cystoscopic sheath upon the completion of the dilatation. The catheter has a marker for easy visualization so that the balloon can be positioned reliably and a tip construction so that the catheter can be advanced into the bladder safely.

    摘要： A catheter for delivering a therapeutic or diagnostic agent to a branch blood vessel of a major blood vessel, generally comprising an elongated shaft having at least one lumen in fluid communication with an agent delivery port in a distal section of the shaft, an expandable tubular member on the distal section of the shaft, and a radially expandable member on the tubular member. The tubular member is configured to extend within the blood vessel up-stream and down-stream of a branch vessel, and has an interior passageway which is radially expandable within the blood vessel to separate blood flow through the blood vessel into an outer blood flow stream exterior to the tubular member and an inner blood flow stream within the interior passageway of the tubular member. The radially expandable member is located down-stream of the shaft agent delivery port, and has an expanded configuration with an outer diameter larger than an outer diameter of the tubular member. The expanded radially expandable member is configured to decrease the blood flow in the outer blood flow stream down-stream of the branch vessel. The catheter provides for delivery of an agent to a branch vessel of a major vessel, and continuous perfusion of the major blood vessel. Another aspect of the invention is directed to methods of delivering a therapeutic or diagnostic agent to one or both kidney's of a patient.

    摘要： An optical fiber device for forming channels within a wall of a patient's heart, and particularly the epicardium, which has an elongated optical fiber, a probe tip secured to the distal end of the optical fiber and an outer support tube secured to the proximal portion of the probe tip and a distal portion of the optical fiber proximal to the probe tip. A handle is described for a flexible optical fiber device which greatly facilitates delivery of the distal end of the optical fiber device to a desired location on the exterior of a patient's heart.

    摘要： An laser device for forming channels within an outer wall of a patient's heart which has an elongated optical fiber, a lens or probe tip secured to the distal end of the optical fiber and means to limit the penetration of the probe tip or lens. Preferably, an outer support sleeve is secured to the proximal portion of the probe tip and a distal portion of the optical fiber proximal to the probe tip. In one preferred embodiment of the invention, a helical coil is disposed between the distal portion of the optical fiber and the proximal portion of the probe tip to ensure a better bond therebetween, particularly when the optical fiber has a lubricous fluoropolymer coating.

    摘要： An intraluminal catheter with an elongated tubular shaft with proximal, intermediate, and distal shaft sections for positioning a therapeutic or diagnostic device within a patient's body region such as a heart chamber. The intermediate shaft section has greater flexibility than the proximal or distal shaft sections, and is preferably of sufficient flexibility to easily assume the curvature of the patient's aortic arch, and reduce the force of contact between the catheter distal end and tissue defining the patient's body region to thereby reduce restriction on the rotation of the catheter. The flexible intermediate shaft section is preferably of a length to occupy a significant portion of the aortic arch, and the catheter overall length is preferably sufficient to have a catheter proximal extremity extending out of the patient and a distal extremity extending at least into an aortic passageway adjacent the patient's left ventricle.
