Abstract
A method of treating a vertebra, comprising: (a) accessing an interior of a vertebra; and (b) introducing a sufficient amount of artificial biocompatible material which does not set to a hardened condition in storage, into said bone, with sufficient force to move apart fractured portions of said bone.
Claims18
A surgical set comprising:
- at least one tool adapted to deliver a material into a vertebra, the tool including a pressure delivery mechanism which comprises;
- a) a body which contains a piston and has an input port;
- b) a delivery tube which is connected to the body through which the material is delivered to a patient's vertebra;
- and
- c) a hydraulic actuator which is connected to the body at the input port for delivering hydraulic fluid under pressure to the body to push against the piston to cause material in the delivery tube to be delivered to the patient's vertebra, the hydraulic actuator being a pump which comprises a piston and a cylinder having matching threads so that the hydraulic fluid can be pumped by rotating the piston;
- and
- at least 1 cc of artificial biocompatible prepared material contained within the delivery tube, in which the pressure delivery mechanism is capable of delivering the material at a pressure of above 10.13 MPa (100 atmospheres).
