Parodi Guidewire

Exchanging guidewires in interventional procedures are a coordinated effort by multiple members of the interventional team. Every guidewire exchange requires the following steps:

1. The interventionalist or surgeon stops the procedure.
2. They must insert an exchange catheter over the existing guidewire.
3. Remove the guidewire.
4. The assistant receives the guidewire for wipe down and preparation for use again.
5. The assistant then hands the interventionalist the next guidewire.
6. The interventionalist then inserts the new guidewire and advances it to the desired location.
7. The exchange catheter is then removed so the procedure may continue.
8. The assistant must then flush and wipe down the exchange catheter for later use.
   
   

Unmet Clinical Needs:

• Reduced frustration and risks of guidewire exchanges –Each one of these steps adds risks and increases valuable operative time.
  • ISI’s Guidewire is designed to essentially perform the functions of three basic wire types without wire removal or exchange, eliminating the need for the orchestrated maneuvers previously described.
• Easy exchange between floppy and stiff wires without wire exchanges – As exchanges of guidewires are so time consuming and frustrating, interventionalists must struggle with guidewires that are gentle but too floppy to push or stiff and drivable but not a traumatic enough. This is very risky and can easily lead to problems.
  • ISI’s Guidewire has the unique ability to change stiffness and size whenever needed without exchange.
• A guidewire that accesses the target location and then becomes the treatment delivery guidewire – When interventionalists traverse the vasculature toward the target location, (carotid artery, renal artery, tibial etc.) they tend to use guidewires sized and best suited for that purpose. Then when the target is reached the treatment guidewire is needed, sometimes a smaller diameter (.014) or more rigid guidewire (Extra Stiff) is required.
  • ISI’s Guidewire has been designed with these specific needs in mind, enabling superior access handling, combined with optimal treatment guidewire requirements (.014, .035 floppy and .035 Extra Stiff) all in one guidewire.
