Devices and Methods for Securing Medical Devices within an Anatomy

A securing device comprising:

• a stent defining a delivery lumen, the stent configured to be disposed in a body lumen defined by a body lumen wall having an inner surface and an outer surface;
• a shape memory suture comprising a proximal stop tab, a distal sharp tip, and a body having length extending between the proximal stop tab and the distal sharp tip, the body of the shape memory suture including an edge extending along the length of the body that inhibits axial rotation of the shape memory suture during deployment, and the body of the shape memory suture assuming a curved shape during deployment such that the distal sharp tip is configured to pierce the inner surface of the body lumen wall and re-pierce the inner surface of the body lumen wall so that the shape memory suture does not pierce the outer surface of the body lumen wall and the body lumen wall is only partially penetrated in a deployed configuration following deployment;
• and
• wherein the suture is configured for deployment from the delivery lumen positioned within the body lumen.
