Abstract

Methods, apparatus, and systems for occluding a left atrial appendage are provided. One embodiment includes an elongate body having a tissue apposition member extendably positioned within a lumen of the elongate body to appose tissue of the LAA. An energy emitting device coupled to the elongate body can be used for emitting high intensity focused ultrasound to the tissues to fuse the tissues.

Claims

exact text as granted — not AI-modified
1 . An occlusion apparatus to fuse tissues, comprising:
 an elongate body having a tissue apposition member extendably positioned within a lumen of the elongate body to appose tissue; and   an energy emitting device to deliver energy to tissues to fuse the tissues.   
     
     
         2 . The occlusion apparatus of  claim 1 , where the energy emitting device can emit RF energy. 
     
     
         3 . The occlusion apparatus of  claim 1 , where the tissue apposition member is formed of a shape memory material.
