A delivery device for a monomer may include an elongate container designed to enclose one or more ampoules containing the monomer. The elongate container may include: a connection at a first end of the elongate container for delivering the monomer to a mixing device, pre-filled with a polymer, for preparation of bone cement composition under vacuum; a cap at a second end of the elongate container; at least one air inlet aperture in a wall of the elongate container; and a manually actuatable element for opening the one or more ampoules. The manually actuatable element may include: a knob; a draw rod; and one or more spikes. The knob may be in threaded engagement with the draw rod. An end of the draw rod may extend past the one or more ampoules. Turning the knob may cause the one or more spikes to penetrate the one or more ampoules.

The delivery device of claim 9, wherein at least a portion of the rod is disposed between the first ampoule and the second ampoule. 13. The delivery device of claim 1, wherein the container has a longitudinal axis, and the rod is substantially aligned with the longitudinal axis. 14. The delivery device of claim 13, wherein the rod has a first portion at the proximal end of the rod having a first diameter threadably engaged with the knob, and a second portion, intermediate the first portion and the distal end of the rod, having a second diameter. 15. The delivery device of claim 9, wherein the rod has a first portion at the proximal end of the rod having a first diameter threadably engaged to the knob, and a second portion, intermediate the first portion and the distal end of the rod, having a second diameter, the second diameter being less than the first diameter. 16. A delivery device for a monomer, comprising: a container having a delivery duct at a distal end and an opening at a proximal end;at least one ampoule containing the monomer disposed within the container, the at least one ampoule having a proximal end and a distal end;a rod having a proximal end that extends through the opening in the container and a distal end disposed within the container, wherein the rod is not rotatable relative to the at least one ampoule;at least one spike connected to the distal end of the rod, the at least one spike disposed between the delivery duct and the distal end of the at least one ampoule, the at least one spike having a piercing end; andan actuator rotatable attached to the proximal end of the rod, the actuator being rotatable from a first position, whereat the piercing end of the at least one spike is spaced apart from the at least one ampoule, to a second position, whereat the piercing end of the at least one spike penetrates the at least one ampoule. 17. The delivery device of claim 16, wherein the at least one spike penetrates the distal end of the at least one ampoule when the actuator is at the second position. 18. The delivery device of claim 16, wherein the actuator is a knob threadably connected to the proximal end of the rod. 19. The delivery device of claim 16, comprising a first ampoule and a second ampoule disposed within the container, the first ampoule and second ampoule being spaced apart within the container; a first spike disposed between the delivery duct and the distal end of the first ampoule; and a second spike disposed between the delivery duct and the distal end of the second ampoule. 20.
