Abstract
The invention concerns a device for carrying out a transespohageal echocardiography and a cardioversion and includes a single endoscope (1) provided at its distal end with an ultrasonic sensor (3) and in the proximity of its distal end with at least one electrode (8) for generating electric shocks. The invention is usefull for the treatment of auricular fibrillation.
Claims10
Device to carry out trans-esophageal echocardiography and cardioversion, comprising:
- an endoscopic tube (1) having a proximal end and a distal end;
- an ultrasonic transducer (3) provided at said distal end and structured to allow connection to an electrocardiographic apparatus;
- an articulation (4) provided in said endoscopic tube, and defining, on one side of said articulation, a proximal portion between said articulation and said proximal end, and on another side of said articulation, a distal portion between said articulation and said distal end;
- control guides coaxially disposed in said endoscopic tube and connecting said distal portion to a control handle (2) provided at said proximal end, for bending said distal portion with respect to said proximal portion;
- at least one first electrode (8) provided on said distal portion;
- a plurality of second electrodes (8) provided on said proximal portion;
- wherein the control guides allow the distal portion to be bent so that the at least one first electrode and at least one of the plurality of second electrodes may be moved toward one another to sandwich intervening tissue;
- each of said first and second electrodes being connected by a cable (9) in said endoscopic tube, each cable being structured to allow connection to a defibrillator to produce electric shocks for a cardioversion.
