International Classification:

A61B 1818

US Classification:

606 41, 606 49, 607102, 607122

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.

International Classification:

A61B018/18

US Classification:

606 41, 607102, 604103

Abstract:

Disclosed is a method for attaching a sensor to an inflatable balloon. The method involves bonding the sensor to the balloon with an adhesive while the balloon is in an expanded state and then collapsing the balloon after the adhesive has at least partially cured. The method reduces the possibility of a failure of the bond between the sensor and the balloon. The method is particularly useful in the construction of a tissue ablation catheter for forming a lesion along a substantially circumferential region of tissue wherein a sensor is used for monitoring the temperature of the tissue being ablated.

International Classification:

A61B 1818

US Classification:

606 41, 606 37, 607122

Abstract:

This invention relates to a surgical device and method. More particularly, it relates to a tissue ablation device assembly and method using a circumferential ablation member in combination with a position monitoring assembly in order to position the circumferential ablation member along a circumferential region of tissue at a location where a pulmonary vein extends from a left atrium.
