Abstract: Embodiments of a balloon assembly are disclosed. The balloon assembly can include an inflatable balloon having an inflated state and a deflated state. The balloon in the deflated state can include a valve retaining portion, a distal tapered portion connected to a distal end of the valve retaining portion, a proximal tapered portion connected to a proximal end of the valve retaining portion, a distal leg connected to the distal end of the distal tapered portion, and a proximal leg connected to the proximal end of the proximal tapered portion. The distal tapered portion can include one or more axial folds. The proximal end of the distal tapered portion can include a first radial fold connected to a second radial fold, the first and second radial folds forming a pocket extending distally at the proximal end of the distal tapered portion.

Abstract: Systems, apparatuses, and methods disclosed herein may be directed to clips for medical implementation, including clips for a portion of a heart. The clips may be configured to close the portion of the heart, to reduce blood flow therethrough as well as passage of clots or other undesired materials. In examples, the clips may be configured to close the left atrial appendage (LAA). The closure of the LAA may reduce the possibility of stroke or other maladies stemming from fluid flow with the LAA. In examples, the clips may be positioned exterior of the LAA, to extend over an outer surface of the LAA for closure.
