Abstract: A guidewire for use in penetrating through complex and stenosed lesions. The distal tip of the guidewire has a roughened surface to increase frictional engagement with calcified and fibrous tissue to increase the penetration of the distal tip and the guidewire into and through the lesion and reduce the likelihood of deflection of the guidewire tip. The average surface roughness of the distal tip is in the range from 1 micron to 200 microns.

Abstract: A torque device for gripping and manipulating a guidewire for advancing the guidewire into a patient's vascular system. The torque device is configured for single-handed use and can be opened for repositioning the torque device relative to the guidewire and closed for gripping the guidewire to prevent axial and rotational movement relative to the guidewire. The torque device grips the guidewire at multiple spaced apart locations on the guidewire.

IPC: A61M25/09
Abstract: A guidewire having improved torque characteristics in a proximal section of the guidewire. The proximal section has a square cross-section and a plurality of twists along the length of the proximal section. The plurality of twists have a pitch in a range from 1 to 3 twists per 1.0 inch so that the guidewire has less than a 15° torque delay when the proximal section is subjected to torsional forces
