Abstract:
1. An apparatus for mixing and dispensing a multi-component bone cement into a vertebrae, comprising: a cannula, sized for insertion into a vertebrae, comprising a proximal end, and a distal end, wherein both the distal end and the proximal end are open and a lumen extends therethrough; a mix and deliver device comprising a barrel having a distal end and a proximal end thereby defining a cavity for mixing a flowable compound therein, wherein the distal end further comprises an outlet in fluid communication with the cavity; a hollow pivot connector configured to link the mix and deliver device to the cannula, wherein the pivot connector comprises a first and a second segment and wherein the first and second segments allow the pivot connector to rotate about two non-collinear axes which are oriented at an angle from each other, each of said first and second segments having a sealing mechanism providing a fluid tight seal within the pivot connector at fluid pressures of 1000 psi to 3000 psi; and a mixing rod having an elongate shaft, said elongate shaft having a lumen therethrough with open ends and a plurality of ports in fluid communication with said lumen spaced along the axial length of the shaft, a handle disposed on a proximal end of the elongate shaft and a mixing element disposed on a distal end of the elongate shaft, the mixing rod slidably disposed within said cavity of said mix and deliver device such that said proximal end of said elongate shaft extends through said outlet and said mixing element is contained within said cavity.
