摘要： A balloon catheter includes a flexible small-diameter guide wire provided with an enlarged-diameter distal end portion, and a flexible elongated tubular shaft with at least one dual-function fluid-conducting lumen adapted to both receive the guide wire extending therethrough, and to communicate pressurized inflation fluid to a distal balloon of the catheter. A distal orifice of the catheter communicates with the balloon and is provided with selective valving means for releasably engaging sealingly with the enlarged distal end portion of the guide wire. Apparatus is disclosed for axially moving the guide wire to effect engagement and disengagement of the enlarged distal end portion with the selective valving means of the catheter shaft. A torquer device is also provided by means of which the guide wire may be rotated relative to the catheter shaft for steering of the guide wire along a vascular pathway. A distal end tapered portion of the catheter shaft provides protection for a joint of the guide wire assembly. The tubular shaft of the catheter may extend through the balloon to provide better pushability for the catheter, especially in versions which employ a comparatively limp material for the balloon. Several alternative constructions for the selective valving means of the catheter shaft and for the enlarged distal end portion of the guide wire assembly are presented.

摘要： A transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient in which the transfer device comprises an integral pump for pressurizing and circulating fluid through a fluid path defined by the transfer device and associated catheter. A removable fluid cartridge is provided including a reservoir from which fluid is drawn by the pump and into which fluid is returned after being circulated through the fluid path. The pump may be a peristaltic pump and the fluid cartridge may include an elongated fluid pick-up having an inlet through which fluid is introduced into the transfer device. The fluid pick-up is sized in length so that the inlet is always submerged in the fluid regardless of the orientation of the transfer device. A removable treatment cartridge having a lumen forming part of the fluid path may also be provided, and a storage sleeve for the treatment cartridge may be of a radiation-blocking material, such as quartz. Further, the treatment cartridge may have a memory for storing and indicating selected information about the treating element.

摘要： A hemostasis valve for sealing around elongate medical instruments inserted into the body. The valve has an elastomeric valve body adapted to be received with a rigid introducer housing and seal thereagainst. The valve body has a distal end and a proximal end, and a cavity opening at the proximal end to receive the medical instruments. A pair of duckbill walls extends in the distal direction and converges and meets at a slit opening. The slit opening has an H-shape that effectively seals around multiple sizes of medical instruments, from the smallest catheter to the largest bore catheters. The duckbill walls may be planar or curvilinear, and may be reinforced with one or more ribs extending outward therefrom.

摘要： A system for delivering and implanting a radially expandable endoluminal prosthesis within a body lumen (e.g., blood vessel). The system comprises a) an introducer/dilator assembly, and b) a delivery catheter/loader assembly. The introducer/dilator assembly comprises an elongate tubular introducer sheath which may be provided with a valving assembly mounted on the proximal end thereof. Such valving assembly may incorporate i) a hemostatic valve, ii) a first sealing valve and iii) a second sealing valve, positioned in series, to prevent leakage of body fluid out of the proximal end of the introducer and to permit two or more elongate members (e.g., catheters, guidewires) having differing outer diameters to be inserted through the introducer without leakage of body fluid therefrom. A dilator, which has regionalized differences in stiffness, is initially deployable within the lumen of the introducer to facilitate advancement of the introducer to its desired location within the body. Thereafter, the dilator may be removed from the introducer sheath and the delivery catheter/loader assembly may be attached to the introducer, such that the delivery catheter having the prosthesis mounted thereon may advanced through the introducer, to a desired location within the body. Thereafter, the radial expandable endoluminal prosthesis mounted on the delivery catheter is deployed and implanted by an expansion device (e.g., balloon) formed on the delivery catheter. The delivery catheter may incorporate one or more outflow apertures at specific location(s) to facilitate injection of radiographic contrast medium in a manner which will check for leakage around the endoluminal prosthesis, after the endoluminal prosthesis has been radially expanded and implanted.

摘要： An intraluminal catheter for directing a guidewire and/or catheter in a desired direction within a bodily vessel or cavity. The intraluminal catheter has a first elongate tubular member and a support means which can comprise a second elongate tubular member that can pass over a main support guidewire. The catheter acts as a platform as the guidewire is passed through the first elongate tubular member and is deflected transversely outwardly by an angled surface through an aperture. A second intraluminal catheter has a first elongate tubular member and a support means comprising a second elongate tubular member. The first elongate tubular member has a main portion and an end portion, with the end portion being deflectable relative to the locus of the main portion so as to direct the guidewire passing through the end portion in a desired direction in the bodily vessel.

摘要： A hemostasis valve assembly adapted for use within a catheter introducer is disclosed. The valve assembly includes first, second and third sealing members wherein the second sealing member comprises a guide wire seal. The guide wire seal includes a plurality of lip members defining two pairs of diametrically opposed slits and an aperture intersecting at least one of the slits. The aperture is adapted to sealing engage a small diameter guide wire for preventing fluid flow out of the catheter introducer through the valve assembly, while the slits allow for the passage of a large diameter elongated member or catheter. Two pairs of diametrically opposed pre-load ribs extend radially towards the aperture for pressing the lip members together in sealing engagement. A substantially spherical inner surface is provided for guiding the guide wire to the aperture.
