1. A cardiac implantation device, comprising:
a first connecting member having a proximal end configured to be coupled to a pacemaker; and
N support struts, each of the N support struts comprising an anchor and having a proximal end coupled to a distal end of the first connecting member, wherein: the anchor is configured to secure the pacemaker during implantation; and each of the support struts has a distal end that is free and is able to radiate outwardly or converge inwardly, where N is a natural number greater than or equal to 1;
wherein the anchor is arranged at a distal end of the support strut;
wherein N is greater than 1, and all the proximal ends of the N support struts are evenly arranged along half of a circumference of a distal end portion of the first connecting member, and nothing is provided at another half of the circumference of the distal end portion of the first connecting member, and
wherein the anchor has a barb-like structure.
