Abstract: Embodiments of the present disclosure provide an animal waste collection wearable. The wearable includes a harness member for mounting to a body of an animal. The harness member covers a hind end of the animal while exposing a tail and an anal area of the animal through an opening. The harness member includes a plurality of leg strap members configured to wrap around hind legs of the animal and releasably engage with a fastening means for mounting the harness member to the body of the animal. A first hook member and a second hook member configured on a left arm and a right arm of the opening, respectively and are adapted for securing a waste collection bag to the harness member. The waste collection bag removably mounted to the harness member conceals the opening and ensures complete entrapment of the anal area for collecting excrement of the animal.

Abstract: Described here are devices and methods that may facilitate treatment of a calcified heart valve with shock waves. A shock wave valvuloplasty device may be advanced through a patient's vasculature and self-align with cusps of a calcified aortic valve. Alignment may be facilitated by a central anchor and/or U-shaped distal bends of positioning wires. An elongated carrier may be slidably disposed over a portion of the positioning wire and carry one or more electrode assemblies that may generate shock waves. An inflatable balloon may sealably enclose the electrode assembles, and shock waves may propagate through the liquid-filled balloon and transfer energy to adjacent calcified valve cusps. The shock wave valvuloplasty device may comprise one or more features to direct shock waves to specific areas of calcified tissue. Some variations also comprise a central anchor configured to be positioned below the valve leaflets.
