Abstract:
1. A medical device, comprising: a catheter body defining a proximal portion, a distal portion, and a longitudinal axis; an expandable element defining a proximal end and a distal end, the proximal end being coupled to the distal portion of the catheter body; a tip element including a distal portion that is affixed to the distal end of the expandable element and being at least partially disposed within the expandable element, the tip element further including a shaft that extends proximally from the distal portion of the tip element and that is slideably receivable within a portion of the catheter body; a tensioning element coupled to the shaft and disposed within the expandable element, the tensioning element being engageable with the distal end of the catheter body and biasing the expandable element toward a pre-determined longitudinal position along the longitudinal axis; and an electrode array defining a substantially closed loop affixed to and extending from the tip element.
