6599254 Multi-feature steerable guidewire for vascular systems July 29, 2003
A vascular system guidewire composed of a helically wound proximal spring segment attached to an additional helically wound distal spring segment of a more radiopaque material by winding the two segments together over a core. The helically wound springs may be tapered from the proximal t
5207229 Flexibility steerable guidewire with inflatable balloon May 4, 1993
A dilation steerable guidewire for use in the vascular system having an inflatable balloon at the distal end and a bi-directional fluid and/or mechanical pressure operated valve forward of the balloon position. The guidewire construction provides torque and improved flexibility for m
5178608 Balloon catheter with expandable inflation member January 12, 1993
A single lumen catheter used alone or in multiples of various diameters in a coaxial disposition over a guidewire or catheter having a means to occlude the distal opening of the single lumen catheter. Each single lumen catheter includes a flexible tube and a balloon disposed about the
5059176 Vascular system steerable guidewire with inflatable balloon October 22, 1991
A dilatation steerable guidewire for use in the vascular system having an inflatable balloon at the distal end and a bi-directional fluid pressure actuated ball valve forward of the balloon position. The guidewire construction provides torque and direction for manipulating the guidewire
4873983 Steerable guidewire for vascular system October 17, 1989
A guidewire arranged to be transported through the vascular system composed of a helically wound tapered spring, a length of tubing attached to the proximal end of the spring, a wire attached to the inner surface of and extending to the tip of the spring for curving the tip to a desired
