INTRAVASCULAR SENSING DEVICE

摘要

A system for detecting electrical activity within a patient's heart comprisi ng an elongated intravascular device (10), such as a catheter or guidewire, having at least one bipolar electrode pair (17, 18) on a dista l section (12) of the elongated device to intravascularly detect electrical activity within the patient's heart. The catheter or guidewire preferably has a tubular shaft (14) formed of braided strands which include a plurality of insulated conductors (15) which are electrically connected to the bipolar electrodes (17, 18).
