Longer core taper

 * Facilitates to negotiate bends/tortuous anatomy without kinking.

ACS Hi-Torque traverse

ACS Hi-Torque intermediate

PT Graphix

Luge

Shorter core taper

 * Shorter abrupt transitions for greater distal support. Helps distal device placement in suitable anatomical locations

Cordis Stablizer

Cordis Stablizer plus

Platimum Plus

ChoICE Extra Support

Continuos grind

 * Due to the absence of transitions, wire tracking is smoother in tortuous anatomy and less likely to bend.
 * Improved crossability. This property increases risk of perforation.

ACD Hi-Torque Whisper

Nitinol

 * Superelastic alloy
 * Excellent steerability
 * Risk of perforation
 * High durability - for multivessel wiring.
 * To have good pushability nitinol has to be combined with stainless steel in the shaft.

Entirely Nitinol
Terumo Cross Wire

Stainless steeel guidewires

 * Not as felxible as superelastic allosy, but has excellent pushability.
 * Most wires belong to this group, except for eg ACS Hi-torque balace bamily and Terumo cros wire

Core-to-tip

 * Enhances steering capabilities and tip control. Less propensity to prolapse.

Tip and intermediate coils

 * Intermediate and tip coils cover the tapered core of the wire.
 * Coils build the core to a constanct diameter and provide improved device trackacility.
 * Tip coils ae alway a radiopaqwue.
 * Intermediate coils can be made radopaque for better visibiltiy.

Polymer over core and tip

 * Polymer and hyodrphiolic coating reduce friction.
 * Coated tip had more plastic therefore may feel stiffer.
 * Poor shapeability.
 * Poor tactile feeback.

ChoICE PT

PT Graphix

Polymer with tip coils

 * Polymer has more surface contact.
 * Some polymers hlep to reduce friction.
 * Soft plastic is not recommneded with DCA

Ploymer cover for lubricity
ChoICE Luge

Bare core and tip coils
Larer core for more support. More surface contact. Coiling reduces friction. Less than 0.014" intermediate section. good support for device devery. DCA, increased space for plaque.
