Abstract: A replacement heart valve system may include a replacement heart valve implant including an expandable framework and a plurality of valve leaflets disposed within the expandable framework, and a filter element secured to the expandable framework and configured to be deployed downstream of the expandable framework, the filter element having a closed downstream end. A replacement heart valve system may include a filter element configured to be deployed across a native heart valve, wherein the filter element includes a lumen extending therethrough, and a replacement heart valve implant configured to be deployed within the lumen of the filter element. A method of treating a native heart valve may include deploying a filter element across the native heart valve, expanding an expandable balloon within the lumen of the filter element, and thereafter, deploying a replacement heart valve implant within the lumen of the filter element.

Abstract: A balloon system for balloon aortic valvuloplasty includes a delivery catheter, an outer expandable member coupled to the delivery catheter, and an inner balloon disposed within the outer expandable member. The outer expandable member has a first length, and a preset hourglass shape defined by first and second bulbous portions separated by a waist region. The inner balloon is non-compliant and has a second length shorter than the first length.
