Tip visibility (radiolucency) and markers
Push transmission/steer ability: ability of a guide wire tip to be delivered to the desired position in a vessel
Torque transmission: ability to transmit rotational forces from the operators hand to the tip
Body support/ track ability: ability to advance balloon catheters/other devices on Guidewire
Tip support/mobility: Allows moving the distal tip to search for the true lumen
Tip durability/elasticity: Permits shape memory retention of the distal tip throughout
Tactile feedback: “feel” of the wire tip’s behavior, as perceived by the operator
better appreciated with non-coated/hydrophobic coated, coil tipped wires and it with hydrophilic coating.
