Torque Device for Procedures Using Guidewire


Torque device for one-handed manipulation of guidewire during endovascular, interventional and catheterization lab procedures.

Key Benefits

  • Enables single-person, one-handed use.
  • Prevents ejection of guidewire during torque device removal.
  • Allows placement of torque device anywhere on the wire.

Market Summary

Interventional procedures, endovascular procedures, and cardiac catheterization labs (cath lab) all involve the use of tiny instruments for minimally invasive treatment, diagnosis, or surgery. Guidewires are used to navigate wires during procedures and act as guides to larger catheters. The insertion of the guide wire is controlled by a torque device, which allows a surgeon to advance, rotate and grip the wet hydrophilic coating of the guidewire. Because the torque device is introduced through the distal end of the guidewire, it requires the assistance of another individual (surgical technician) to advance the torque device from the furthest point away from the patient. Current torque devices require the surgeon use two hands to control the tightening, advancing, and loosening of the device. Removal of the torque device often results in the unintended removal of the guidewire tip from its desired location, resulting in longer procedure time and additional radiation exposure time for the patient.

Technical Summary

Emory inventors have developed a universal torque device which can be operated with one hand. The device is designed for use with a variety of guidewire sizes and is not limited to placement on the distal end of the guidewire, enabling more flexibility in use. This torque device is also designed to be easy to release, preventing the ejection of the guidewire upon removal. Allowing the placement, tightening, and loosening of the guidewire with one hand eliminates the need for assistance from a second person. The torque device helps make procedures safer and quicker for both the patient and staff.
