Apparatus and method for fixation of osteoporotic bone

An injection device in combination with an injectable material comprising:

• an elongated guide wire, said guide wire having a first end and a second end connected by an elongated guide wire body, and said first end being configured with a taper, said taper being capable of breaching cortical bond sufficient to form a channel through said cortical bone;
• an aligning cannulae having a gripping end and a tapered end, said aligning cannulae being sized and configured to slidably pass circumferentially over said guide wire;
• a delivery cannulae having a proximal end and a distal end, which are connected by a cannulae body;
• and a lumen capable of acting as a material conduit, said lumen passing from said proximal end through said distal end, said delivery cannulae being sized and configured to slidably pass circumferentially over said aligning cannulae;
• an elongated plunger, said plunger being sized and configured to slidably pass through said lumen so as to force said injectable material through said lumen while permitting air from said lumen to escape proximally past said plunger;
• a removable handle configured for secure attachment to said proximal end of said delivery cannulae, said delivery cannulae being equipped with a handle retention member integrally formed in said proximal end of said delivery cannulae;
• and
• an injectable material provided to said lumen of said delivery cannulae, said injectable material being of a consistency such that upon controlled movement of said plunger, said injectable material will flow through said lumen.

An intraosseous device comprising:

• an elongated guide wire, said guide wire having a first end and a second end connected by an elongated guide wire body, and said first end being configured with a taper, said taper being capable of breaching cortical bone sufficient to form a channel through said cortical bone;
• an aligning cannulae having a gripping end and a tapered end, said aligning cannulae being sized and configured to slidably pass circumferentially over said guide wire;
• a delivery cannulae having a proximal end and a distal end, which are connected by a cannulae body, and a lumen capable of acting as a material conduit, said lumen passing from said proximal end through said distal end, said delivery cannulae being sized and configured to slidably pass circumferentially over said aligning cannulae;
• an elongated plunger, said plunger being sized and configured to slidably pass through said lumen so as to force said injectable material through said lumen while permitting air from said lumen to escape proximally past said plunger;
• a removable handle configured for secure attachment to said proximal end of said delivery cannulae, said delivery cannulae being equipped with a handle retention member integrally formed in said proximal end of said delivery cannulae.

A method of introducing an injectable material into a subject, the method comprising:

• introducing a guide wire through the cortical bone of a subject;
• introducing an aligning cannulae circumferentially over said guide wire until said aligning cannulae contacts said cortical bone;
• introducing a delivery cannulae having a lumen circumferentially over said aligning cannulae until said delivery cannulae contacts said cortical bone;
• removing said guide wire and said aligning cannulae from the subject;
• infusing an injectable material into said lumen, and infusing said injectable material into the bone of said subject by movement of a plunger, said plunger being sized and configured to force said injectable material through said lumen of said delivery cannulae while permitting air from with said lumen to escape proximally past said plunger.
