摘要： 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.

摘要： A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.

摘要： A guidewire formed from drawn filled tubing having an inner core member encased in an outer layer. The inner core member is formed from a linear elastic or superelastic material and the outer layer is formed from a metal alloy such as 35N LT. A portion of the outer layer is ground down to form a feather edged joint between the outer layer and the inner core member.

摘要： A shaping tool is used to form a bend in the distal end of a guidewire. The guidewire distal end is inserted through a channel and into a cavity of the shaping tool. Using hand pressure, a first member is moved axially relative to a second member of the shaping tool, thereby moving the cavity relative to the channel and imparting a bend in the distal end of the guidewire.
