An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device embodiments utilize an inflatable balloon or expandable element used to occlude the treatment site.

Occlusion systems

System and methods of delivering adhesive material are described for occluding target locations within a patient. The systems include a catheter configured to deliver adhesive to a target location and one or more of a light source to harden the adhesive, a retention structure to contain the adhesive prior to curing, a balloon to occupy a target location, and an open cell foam plug to occupy a target location.

Adhesive occlusion systems

An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device utilizes an inflatable balloon comprising a proximal portion to inflate with an inflation fluid delivered by an outer catheter body and conform to a shape of the left atrial appendage and a distal portion to fill with an adhesive delivered by an inner catheter body. The distal portion of the inflatable balloon sticks to the tissue wall of the left atrial appendage. The outer catheter body is configured to position the inner catheter body inside the outer catheter body.
