Product Details

The Trapezoid RX Wireguided Retrieval Basket is designed for the crushing and removal of stones in the biliary duct. The Flexi-Stiff™ Catheter construction provides a flexible and sturdy catheter designed to bend with biliary anatomy while maintaining pushability. The metal alloy basket is designed to maintain basket symmetry even after difficult stone manipulation.

Tip Disengages

Tip disengages to facilitate basket removal if stone does not break, helping to reduce risk of basket impaction.

Mechanical Stone Crushing Option

The Alliance™ II Inflation System can be used to crush large stones trapped within the basket with scope in place

  • Injection with wire in place accommodates cholangiography without device exchange
  • The RX Locking Device facilitates multiple sweeps of the duct during stone retrieval by maintaining guidewire position
