  • Tissue ablation device assembly and method for electrically isolating a pulmonary vein ostium from an atrial wall
    Patent number: 6997925
    Abstract: This invention is related to a tissue ablation system and method that treats atrial arrhythmia by ablating a circumferential region of tissue at a location where a pulmonary vein extends from an atrium. The system includes a circumferential ablation member with an ablation element and also includes a delivery assembly for delivering the ablation member to the location. The circumferential ablation member is generally adjustable between different configurations to allow both the delivery through a delivery sheath into the atrium and the ablative coupling between the ablation element and the circumferential region of tissue.

  • Medical device with sensor cooperating with expandable member
    Patent number: 6547788
    Abstract: A tissue ablation catheter for forming a lesion along a substantially circumferential region of tissue is described. The catheter includes one or more sensors for monitoring the temperature of the tissue being ablated. The temperature sensors are mounted on the interior or exterior of an expandable member that is affixed to a shaft of the catheter.
