METHOD AND SYSTEM FOR CONNECTING A LEAD TO CARDIAC TISSUE

摘要

The invention relates to a method of connecting a lead to cardiac tissue in a patient's body, comprising the steps of: a) providing an elongated hollow delivery tool having a proximal end and a distal end, b) inserting the distal end of the tool into the patient's body, c) navigating the delivery tool until its distal end contacts the cardiac tissue at a contact location, d) determining if the contact location is suitable for connection of the lead, e) if the contact location is deemed suitable, fixedly connecting an electrode of the lead to the cardiac tissue at that location, and f) if the contact location is not deemed suitable, moving the distal end of the delivery tool away from the cardiac tissue and navigating the delivery tool until its distal end contacts the cardiac tissue at an alternative contact location that is spaced apart from the previous contact location, and repeating step d). The invention further relates to a system for connecting a lead to cardiac tissue in a patient's body, comprising: an elongated hollow delivery tool having a proximal end and a distal end, the distal end being arranged for insertion into the patient's body, a navigating device for navigating the distal end of the delivery tool to a contact location on the cardiac tissue, a determinator for determining the suitability of the contact location, and a connecting device for fixedly connecting an electrode of the lead to the cardiac tissue at a selected contact location.
