Abstract:
1. A blood clot removal device, comprising: a capture member having tubular body of prevailing longitudinal extension and provided with a lumen longitudinally extending in said tubular body, said tubular body having at least one proximal portion, at least one distal portion, an apical end of said distal portion, and a tip; said at least one distal portion of said capture member having at least one helical length provided with coils wrapped in an helical manner forming a pitch (p) one relative to the other in the longitudinal direction, wherein the at least one distal portion of said capture member takes the at least one helical length when in a relaxed condition; an inner cable received in said longitudinal lumen of said tubular body so as to extend through an entirety of said helical length of the tubular body, said inner cable comprising a proximal length having a proximal manoeuvring end and a distal length provided with a tip; wherein at least one securing portion of said distal length of said inner cable is secured to said apical end of said tubular body of the capture member, said securing portion being firmly secured to said apical end so that, when said inner cable is subjected to a relative movement relative to the capture member in the proximal direction, said inner cable brings the apical end of the tubular body closer to the proximal portion thereof shortening the pitch (p) of said coils of the helical length of the capture member.
