1. A device for anchoring a prosthetic heart valve on biological tissue, the device comprising:
- first and second anchoring assemblies mutually couplable to secure biological tissue therebetween, wherein the anchoring assemblies include at least one pair of complementary arched portions having anchoring formations for anchoring on the biological tissue, such that the anchoring formations include extensions which are rigidly connected to the anchoring assemblies and extend radially outwardly from one of the anchoring assemblies in an alternate arrangement with respect to corresponding extensions extending radially outwardly from the other of the anchoring assemblies, whereby, with the anchoring assemblies mutually coupled to secure the biological tissue therebetween, the extensions in the complementary arched portions interdigitate, wherein, in at least one of the anchoring assemblies, the extensions have different lengths over different portions of the respective anchoring assemblies.

12. A device for anchoring a prosthetic heart valve on biological tissue, the device comprising:
- first and second anchoring assemblies mutually couplable to secure biological tissue therebetween, wherein the anchoring assemblies include;
at least one first pair of complementary arched portions having alternate arrangement of extensions to interdigitate and impart to the biological tissue secured therebetween a serpentine-like trajectory; and
at least one second pair of complementary arched portions having the anchoring assemblies extending radially outwardly of one of the anchoring assemblies in an aligned arrangement with respect to homologous extensions extending radially outwardly of the other of the anchoring assemblies, whereby, with the anchoring assemblies mutually coupled to secure the biological tissue, the extensions in the second pair of complementary arched portions form couples of co-operating extensions securing therebetween the biological tissue in a linear trajectory. - View Dependent Claims (13, 14)
