Abstract

L'elettrocatetere di mappatura in oggetto prevede all'interno di una guaina (1) tubolare: una prima spirale (2) in materiale biocompatibile ed elettricamente isolata, inseribile in cavità del muscolo cardiaco per via intravenosa, e presentante una porzione operativa (2a) scoperta dalla guaina (1) e dotata di un secondo anello (4) di chiusura dell'estremità; un secondo anello (5) definente un sensore dell'attività elettrica cardiaca, in materiale biocompatibile ed elettricamente conduttore posto coassialmente alla prima spirale (2) e mobile lungo la porzione operativa (2a) mediante una seconda spirale (6); quest'ultima è disposta coassialmente alla prima spirale (6) e collegata, all'estremità opposta, a mezzi (7) di comando e movimentazione della stessa; dei mezzi (8) di variazione della conformazione della porzione operativa (2a) della prima spirale (2) agenti tra l'anello di chiusura (4) e l'estremità della guaina (1), costituiti da un tirante (9) flessibile azionabile assialmente rispetto alla prima spirale (2) cosi da permettere una variazione della lunghezza della corda sottesa dalla prima spirale (2) in funzione della conformazione presentata dalla cavità.
