Explantation accessory for an intracorporeal capsule

An explantation accessory for an intracorporeal capsule comprising a tubular body provided at its distal end with an anchoring screw member adapted to penetrate into tissue of a wall of an organ of a patient, the explantation accessory comprising:

• a catheter comprising a hollow tube carrying at its distal end a steerable head comprising a tubular receptacle directed axially and defining an interior volume suitable for housing the capsule at least in the proximal part thereof;
• and
• a lasso comprising a flexible wire extending along the catheter and forming at its distal end a deformable loop emerging from the catheter, the loop extending between two ends configured on two opposite ends of the catheter hollow tube, at least one of these ends of the loop being mobile relative to the catheter so as to allow tightening of the loop under the effect of a traction exerted on the flexible wire proximally along the catheter, and vice versa;
• wherein the free end edge of the tubular receptacle comprises:
• a protruding anterior portion;
• an axially recessed posterior portion with respect to the anterior portion and located diametrically opposite to the protruding anterior portion;
• and
• two beveled edges connecting the protruding anterior portion to the recessed posterior portion.
