Title:
INJECTION NEEDLE FOR FRACTURES
Document Type and Number:
WIPO Patent Application WO/2012/134664
Kind Code:
A3
Abstract:
A cannula having proximal and distal ends defines a hollow body. A tissue-piercing tip is formed at the distal end of the cannula and is fluidically sealed from the hollow body. At least one opening is formed in a sidewall of the cannula and fluidically coupled to the hollow body. A fracture may be treated by advancing the tip through soft tissue so that the at least one opening is at least partially disposed within or adjacent to the fracture. The needle is oriented so that the at least one opening faces an exposed end of fracture or within the plane of the fracture line. Then, a therapeutic composition, such as a bone growth factor, is pressured through the hollow body to exit from the at least one opening.
