摘要： The present invention is a distal protection device for use during a vascular treatment, such as angioplasty or atherectomy. A filter assembly located on the distal end of a delivery member is deployed distally of the vascular region to be treated to capture emboli released during and immediately after the procedure. The filter is then retracted to retain any captured emboli and then removed from the patient.

摘要： Methods of fabricating medical vascular catheters adapted to be inserted into a blood vessel from an incision through the skin of a patient for introducing other devices or fluids for diagnostic or therapeutic purposes and particularly methods for fabricating such catheters with catheter bodies having catheter sections of differing flexibility are disclosed. Such catheter bodies having a proximal catheter body end and a distal catheter body end and formed of a proximal section and at least one distal section that have differing flexibilities are formed in a process comprising the steps of: (1) forming a continuous tubular inner jacket preferably of an inner liner and a reinforcement layer; (2) forming initial layer segments having an initial layer thickness along the length of the inner jacket from a material of first durometer hardness, whereby each initial layer segment is separated by a separation distance: (3) forming a final layer of a material of second durometer hardness with a second layer thickness over the tubular inner jacket along the separation distances and over and/or against the proximal and distal initial layer ends of the initial layer segments to form a continuous catheter body tubing; (4) severing the continuous catheter body tubing into catheter body lengths including a proximal catheter section formed of the material of second hardness and a distal catheter section of the material of first hardness; and (5) completing the catheter fabrication at the proximal catheter body end and the distal catheter body end. Centerless grinding of the catheter body or body tubing, formation of Intermediate catheter body sections, distal soft tips, and discontinuities in the reinforcement layer formed prior to step (2) are also disclosed.

摘要： The present invention comprises a tubular catheter shaft defining at least one catheter shaft lumen and a radiopaque band made of a polymeric material loaded with a radiopaque material of greater than 40% by weight, suitable for visualization under fluoroscopy in catheters in the range of 3 French to 5 French. The distal soft tip is formed of a relatively flexible polymeric material, loaded with radiopaque material which is less radiopaque than the radiopaque band. The radiopaque band's proximal end adjoins the distal end of the catheter shaft. The radiopaque band's distal end adjoins the proximal end of the distal tip to form an attachment junction. A tubular sleeve fits coaxially over the radiopaque band, the distal end of the catheter shaft and the proximal end of the distal soft tip. The tubular sleeve adheres the catheter shaft distal end to the proximal end of the radiopaque band and adheres the soft tip proximal end to the distal end of the radiopaque band thereby aligning the soft tip lumen, the radiopaque band lumen, and the catheter shaft lumen. The proximal end of the tubular sleeve is bonded to a distal portion of the catheter shaft. The distal end of the tubular sheath is bonded to the proximal end of the soft distal tip. The radiopaque band is bonded to the tubular sheath thereby bridging the attachment junction. The tubular sleeve is made of a polymeric material loaded with a radiopaque material which is less radiopaque than the radiopaque band. The tubular sleeve is melt compatible with the radiopaque band, the catheter shaft distal end and the distal soft tip such that the tubular sleeve, the distal end of the catheter shaft, the radiopaque band and the proximal end of the distal soft tip bond.

摘要： A hub for connecting a medical catheter in fluid communication with a medical device, such as a syringe, includes a tubular shaped body member which has an outer surface that is formed with a plurality of grips. The hub also has a pair or diametrically opposed wings which extend from the outer surface of the body member and it has a proximal end which is formed as a female luer fitting for engagement with the medical device. The distal end of the hub is formed with a spiral strain relief element having a passageway which receives the proximal end of the medical catheter. In operation, the spiral relief element supports the medical catheter and prevents kinking of the catheter near the hub during flexure of the catheter by providing for a progressive transition from the relative rigidity of the hub to the flexure required by the catheter.

摘要： The present invention relates to a guidewire which comprises an elongated core of a substantially solid cross-section having a distal end portion, the distal end portion having a plurality of notches therein, the notches having a depth of 5-25% of the diameter of the proximal end. The proximal end of the guidewire has a diameter in the range of 0.005-0.040 inches, the notches defining a continuous helix with a constant depth. The guidewire also comprises a helically wound spring, the spring having a plurality of coils defining a lumen. At least part of the distal end portion of the elongated core being received within the lumen. That part of the distal end portion of the elongated core being received within the lumen forming with the helically wound spring an intermediate portion, at least a portion of the coils being disposed within the continuous helix of the elongated core, the helically wound spring being sized and positioned on the elongated core such that a smooth continuous outer diameter is attained over the length of the guidewire. The guidewire also has a means for bonding the coils to the distal end portion so that the guidewire has a continuous stiffness gradient along the length of the guidewire from a stiffest point at the proximal end to a more flexible portion in the distal end portion proximal to the intermediate portion, to a still more flexible portion in the intermediate portion to a most flexible point at the distal end of the helically wound spring. In an alternative embodiment the notches define a continuous helix with a constant depth. This alternative embodiment also has a rounded tip connected to the distal end of the spring and a safety wire connecting the distal end portion and the rounded tip.
