Preformed mandrel for guiding a probe in contact with the wall of the septum

摘要

#CMT# #/CMT# The mandrin has a flexible wire (10) with a distal end introducing in a central lumen of an intracardiac probe. Curvilinear parts (C1, C2) are extended in planes (P1, P2), respectively and form a dihedral angle (phi 3) between the planes. Total length of the curvilinear parts and a straight part (D1) is between 82 and 195 millimeters in a manner to coincide the mandrin with an anatomical curve of a venous network in which the probe is introduced. The part is set at an opening angle (phi 2) ranging between 20 and 40 degree. #CMT#USE : #/CMT# Guiding mandrin for rigidifying an intracardiac probe for permitting to introduce the probe in a venous network and orienting and guiding a distal end of the probe till the probe is contact with a wall of an auricular or ventricle septum. #CMT#ADVANTAGE : #/CMT# The total length of the curvilinear parts and the rectilinear part is comprised between 82 and 195 millimeters in a manner to coincide the mandrin with the anatomical curve of the venous network, thus placing the head of the probe against the wall of the septum in simulation direction chosen by the surgeon in a simple and predictable manner, while ensuring the efficient transmission of the torsion. The mandarin can be implemented in a simple and economic manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a guiding mandarin for implantation adopted to a right edge.
