Abstract: A system for delivering a therapeutic agent to a nasopharyngeal mucosa target comprises a foam generating mechanism, a gas, a therapeutic agent in liquid form that inhibits mucus production, and a delivery device. Actuation of the foam generating mechanism entraps gaseous bubbles from the gas in the liquid thereby forming a foam. The therapeutic agent is dispersed in the foam which has an expanded configuration adapted to fill a nasopharyngeal space and deliver the therapeutic agent to the mucosa targets. The delivery device is for delivering the foam to the nasopharyngeal space. The foam may also have a collapsed configuration for removal from the nasopharyngeal space or for concentration of the therapeutic agent onto the mucosa.

Abstract: A prosthetic heart valve (100) includes a flexible anchoring member (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to, mounted within, or otherwise carried by the valve support. The valve support includes a plurality of posts (122) connected circumferentially by a plurality of struts (124), where the posts extend along an axial direction generally parallel to the longitudinal axis (101) and the struts extend circumferentially around and transverse to the longitudinal axis. The posts extend an entire longitudinal height HI of the valve support 120. The device also includes one or more sealing members (140) and tissue engaging elements (170) like spikes.

Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.
