Covidien Introduces Enhanced Wholey™ Guidewire System for Facilitating Navigation Through Tortuous Arteries
Testing data demonstrates 99 percent less whip compared to the leading competitor
PLYMOUTH, MN – October 15, 2012 – Covidien today announced the launch of its enhanced Wholey™ Guidewire System. The new Wholey Guidewire system delivers improved torqueability and increased lubricity while still combining the right degree of trackability and steerability for access to a wide range of the vascular anatomy.
The Wholey guidewire system is intended to facilitate placement and exchange of interventional devices during diagnostic or therapeutic interventional procedures. The atraumatic design of the guidewire enables it to be torqued to facilitate navigation through tortuous arteries and avoid unwanted side branches. Its shapeable, flexible, radiopaque tip allows for better visualization, and the 1:1 torque offers better control than the previous Wholey hi-torque wire.
Dr. Michael Wholey, Interventional Radiologist, Southeast Baptist Hospital, San Antonio, Texas. “The new wire introduces tremendous torque control with the ability to turn it where you want it. It gives a physician confidence and control in more challenging cases.”
Lab testing was conducted using an AngioDynamics SoftVu® 5F Omni™ Flush Shepherd’s Hook Catheter.* The catheter was placed over a tortuous aortic bifurcation per typical procedures, and the end of the catheter was placed in the iliac/superficial femoral artery (SFA) location. The wire was then torqued multiple times clockwise and counterclockwise.
Lab testing results demonstrate 99% less whip for the Wholey guidewire than the leading competitor, for a more predictable tip response and increased steerability. Whip is a sudden increase in angular acceleration causing an uncontrollable change in distal tip direction. The Wholey family of guidewires is available in levels of support and flexibility to meet various clinical needs.
"The new Wholey wire is definitely an upgrade over prior wires and similar wires on the market today,” said Dr. Tom Davis, Interventional Cardiologist, St. Johns Hospital, Detroit, Michigan. “It has the support of the previous Wholey without the stiff feel to it. It's smooth and supportive for getting a catheter up and over.”
