Abstract: A balloon aortic lithotripsy assembly for placement adjacent an aortic valve. The balloon aortic lithotripsy assembly includes multiple balloon chambers, a shell, and a shock wave generator. The balloon chambers are arranged to establish an open interior residing inboard of the balloon chambers. The shell is located around the balloon chambers. The shock wave generator can be situated on one or more of the balloon chambers, the shell, or both of the balloon chamber(s) and shell. In use, blood is free to travel through the open interior, and the shock wave generator can produce shock waves that are intended to impinge calcified tissues residing at the aortic valve.

Abstract: An antegrade perfusion assembly may have a braided sheath, a three-way stopcock, and a male-to-male connection. The three-way stopcock can fluidly communicate with the braided sheath in assembly. The three-way stopcock can furnish control of perfusate flow amid use of the antegrade perfusion assembly, and can facilitate de-airing of the braided sheath amid use of the antegrade perfusion assembly. The male-to-male connection can fluidly communicate with the three-way stopcock, and can accept reception and securement with an oxygenated blood source amid use of the antegrade perfusion assembly.

Abstract: A left atrial appendage occlusion medical device includes a carrier and a hydrogel polymer. The carrier is for placement within a left atrial appendage of a heart. The carrier can be a spherical shaped structure of a shape memory material or a framing coil of metal material, among other possible examples. The hydrogel polymer is carried by the carrier and hence is placed within the left atrial appendage along with the carrier. The hydrogel polymer is capable of expanding in size when the hydrogel polymer comes into contact with blood fluid. In use, upon placement of the left atrial appendage occlusion medical device within the left atrial appendage, the hydrogel polymer expands in size when it comes into contact with blood fluid.
