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

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

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 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.

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.
