Patent Images
1. A device comprising:
- an outer tube with a proximal end and a distal end;
a pusher tube assembly comprising an inner tube with a proximal end and a distal end and an end cap secured to said distal end of said inner tube;
a clamp collar within said distal end of said inner tube;
legs, each having a proximal end and a distal end;
a retainer located proximally to said clamp collar with slots that allow passage of said legs; and
actuating members connected to said proximal end of said legs;
wherein each of said legs has an outwardly-oriented tab;
wherein said distal ends of said legs are located, before deployment, at said distal end of said inner tube but proximal to said clamp collar;
wherein said legs, said actuating members and said retainer reside within said inner tube; and
wherein said outer tube and said inner tube are connected to a proximal handle that may actuate each leg independently through a separate control cable connected to the proximal end of each of said actuating members of said legs.
