Coronary Guidewires

Many of the guidewires we manufacture at Modern Grinding are Coronary Guidewires. We are a contract manufacturer, we don’t have any of our own products. For our own knowledge base and hopefully for medical device designers, this will help provide a better understanding of coronary guidewires and the different designs. Below are the common guidewires and design considerations:

Some examples of standard guidewires include the BMW (Abbott Vascular), Cougar (Medtronic), IQ (Boston Scientific) and Stabilizer (Cordis).

Depending on the type of surgery you would like to perform, the following guidewire traits must be considered:

Guidewire Torque

Is an ability to apply rotational force at a proximal end of a guidewire and have that force transmitted efficiently to achieve proper control at the distal end

Guidewire Tracking

Is an ability of a wire to follow the wire tip around curves and bends without bucking or kinking, to navigate anatomy of vasculature

Guidewire Steerability

Is an ability of a guidewire tip to be delivered to the desired position in a vessel

Guidewire Flexibility

Is an ability to bend with direct pressure

Guidewire Prolapse Tendency

Tendency of the body of a wire not to follow the tip around bends

Guidewire Radiopacity

Is an ability to visualise a guidewire or guidewire tip under fluoroscopy.

Guidewire Tactile feedback

Is tactile sensation on a proximal end of a guidewire that physician has that tells him what the distal end of the guidewire is doing

Guidewire Crossing

Is an ability of a guidewire to cross lesion with little or no resistance

Guidewire Support

Is an ability of a guidewire to support a passage of another device or system over it
