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: A61B17/22
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 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.

Abstract: 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.

Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium, tungsten, and nickel. Tungsten is present above its solubility limit (about 15%), but is still only present as a super-saturated, primarily single-phase material exhibiting an FCC microcrystalline structure.
