OPERATED CATHETER FOR ENDOSCOPIC INTERVENTIONS Russian patent published in 2012 - IPC A61M25/92 A61B17/94 

FIELD: medicine.

SUBSTANCE: catheter comprises in-built rods on bent portions with distal and proximal side. Pressure rings fasten a spiral through which the rods attached to the pressure ring extend. The proximal end of the catheter extends through a handle with an attachment point of the rods in vertical arrangement of the bent portions. The handle is rocking on the portion from the proximal side to pull some rods which is transferred on the portion of the catheter from the distal end. The spirals are one-side bent together with the portions of the catheter. The bend of the portion of the catheter on the proximal side is copied over the bend of the portion of the catheter on the distal side but on the opposite side. It results in endoscopically-assisted introduction of the catheter in narrowed and deformed passages in complicated clinical situations for the purpose of both diagnostic, and therapeutic endoscopic interventions, by the introduction of the other endoscopic instruments in the catheter.

EFFECT: invention may be used for diagnostic (contrast enhancement) and therapeutic endoscopic introductions (extraction of concrements, masses, cord conduction, recovered passability, etc) in complicated clinical situations.
