Abstract: A mechanism for adjusting the chordae connecting the leaflets of a mitral valve to the papillary muscles in order to restore normal functioning of the mitral valve. The devices or mechanisms can correct problems associated with both prolapsed leaflets and restricted leaflets to allow the leaflets to properly coapt, thereby preventing or minimizing regurgitation. In accordance with the invention, the mechanisms or devices used for adjusting the chordae can be delivered and implanted in a minimally invasive and/or percutaneous manner, such as via transapical methods, transfermoral methods, or trans-septal methods.

Abstract: A skin surface indwelling device for guiding punctures includes: an indwelling tube (13) having an inside tunnel (P) substantially extending along the longitudinal direction of the indwelling tube (13), the tunnel (P) is used for guiding needle (N), the indwelling tube (13) has a proximal end positioned above the skin surface (S) and a distal end positioned under the skin surface (S) in indwelling state; a support (11) having a bottom surface on its bottom that directly or indirectly contacts with the skin surface (S), the support (11) supports and fixates the indwelling tube (13); and a sealing elements (141,142) configured to seal the tunnel (P). The skin surface indwelling device for guiding punctures can shorten the time of establishing a puncture tunnel in the buttonhole puncture method, and help to build the puncture tunnel. In addition, the skin surface indwelling device can also guide the puncture needle (N) when puncturing, and protect the immature puncture tunnel.
