Devices with Aperture Lock for Bone Implantation

An assembly for circulating material in a medical device, comprising an adapter, the adapter comprising:

• a shaft having a proximal end and a distal end,
• a cannula disposed through the center of the shaft between the proximal end and the distal end,
• a female aperture lock formed on the proximal end for reversibly engaging a male taper on a pressure device,
• a male conical surface formed on the distal end configured to reversibly engage a female conical surface on a medical device, and
• a thread disposed peripherally on the shaft between the female aperture lock and the male conical surface, the thread configured to reversibly engage a groove on an inner surface.

A method of injecting material in a medical device, comprising:

• engaging to an adapter a pressure device and a medical device having a scaffold;
• and
• injecting material in the medical device with negative pressure or positive pressure from the pressure device,
• wherein the adapter comprises a shaft having a proximal end and a distal end, a cannula disposed through the center of the shaft between the proximal end and the distal end, a female aperture lock formed on the proximal end for reversibly engaging a male taper on a pressure device, a male conical surface formed on the distal end configured to reversibly engage a female conical surface on a medical device, and a thread disposed peripherally on the shaft between the female aperture lock and the male conical surface, the thread configured to reversibly engage a groove.
