    摘要: A dilatation balloon catheter is disclosed with an inelastic balloon wrapped about a smaller section of a guidewire. During introduction across a region of a stenosis, the balloon is wrapped around a guidewire in such a way that the guidewire contained therein can rotated freely, but cannot advance independently of the balloon. The wrapped configuration is maintained by means of a temporary bond. Inflation of the balloon, following proper positioning of the catheter breaks the bond, permitting the balloon to unwrap from the guidewire contained therein. Typically, the distal end of the guidewire is tapered and the guide wire is controllably clamped to the catheter for advancement into the patient.

    摘要: An exchangeable catheter-guidewire system is disclosed in which the guidewire can be manipulated to seize and to release itself from the catheter body while both are in place in a vasculature or other body vessel. For balloon dilatation catheters, this arrangement permits one to transmit the fluid used for perfusion and/or balloon inflation through the same lumen through which the guidewire passes. Balloon catheters which utilize the invention have the capacity to secure the position of the guidewire relative to the catheter body, as well as to seal the lumen and balloon to retain fluid under pressure, both by remote control from the proximal end of the catheter. The seizure and sealing are achieved by a deformable section on the guidewire, which expands upon deformation to seize a tubular section of the catheter body. Two examples of deformation are given, the first occurring with a deformable section which is sufficiently flexible to gather into folds upon longitudinal compression, the folds being bulky enough to expand outward, and the second occurring with a deformable section which is inflatable. In either case, the guidewire in preferred embodiments is constructed as a hollow tube with a central rod which in both cases serves to enhance the longitudinal strength of the guidewire and, in the first case, also serves as a means of compressing and re-extending the deformable section of the tube. Either mechanism permits the construction of an exchangeable catheter system with the crossing profile of non-exchangeable systems.

    摘要: A radially expandable intravascular medical device is disclosed. The device typically includes two members. The first member is an outer tube-shaped sheath which is radially expandable by being formed from elastic material or other means and having relatively low column strength. The second member is an inner portion extending throughout the outer tube. This inner portion includes a slit to allow it to expand radially as well. Using the structure diagnostic, therapeutic, or other desired objects may be conveyed through the device yet still enable the device to have a smaller cross-sectional area throughout most of its length than the object conveyed therethrough.

    摘要: An elongated rod terminating in an abutment device with a lumen for passage of a guidewire is used to push an angioplasty balloon along the guidewire and through a vasculature to a location where treatment is needed. The balloon is fed by an inflation tube which remains independent of the guidewire and need not have axial rigidity. This combination of components permits one to exchange balloons without the need for a guidewire extending 100 cm or more outside the patient's body. Guidewire exchanges are also possible in cetain embodiments of the concept, and possibilities for perfusion are also presented. The guidewire passes through a tube inside the balloon which can also be used for perfusion of the patient's blood when the guidewire is withdrawn.

    摘要: A dilatation balloon catheter with a non-removable guidewire is disclosed in which the guidewire is joined to the catheter tube through a distortable element, preferably a twistable tube. The element provides a strong fluid-tight connection between the guidewire and catheter tube and yet permits the guidewire to be rotated relative to the catheter tube over a wide range of rotation, with little torsional stress on either the catheter tube, the balloon or any other element of the catheter construction. In preferred embodiments, the catheter construction further includes a column support tube inside the balloon, surrounding a segment of the guidewire toward its distal end, to prevent collapse of the balloon along its longitudinal axis as the balloon is advanced into a stenosis. In these embodiments, the distortable element is joined to the catheter tube through the column support tube which thus serves as an intermediate linkage.

    摘要: Systems and methods for treatment of tricuspid valve disease. The systems and methods can anchor a supplemental valve apparatus in the vena cavae and provide a competent valve positioned in the right atrium or in or through the tricuspid annulus without requiring an anchor in the tricuspid annulus. The supplemental valve apparatus can include a supplemental valve coupled to at least one supplemental valve structure, which can extend into at least one of the inferior vena cava or superior vena cava with the supplemental valve positioned in or adjacent the right atrium. The valve apparatus can be delivered percutaneously by a delivery system, which can include the supplement valve apparatus positioned between an inner and outer shaft that can be retracted to deploy the supplemental valve apparatus in or adjacent the right atrium. Methods of delivery and treating a tricuspid valve by a supplement valve apparatus are also described herein.
