[Device for removing concrements from tubular organs]

Wide use of Dormia's loop for removing the concrements from tubular organs led to development of numerous designs of this device. Search for new designs serves one purpose: decrease the traumatism and risk of injury to the organ during the procedure. The new design is characterized by a longer length of service and is more reliable. It is free from the shortcomings of many known designs used for nonsurgical removal of the concrements from tubular organs, most frequently the ureters and its use is less traumatic.
