Abstract:
1. A biomaterial delivery device comprising an elongated handheld powder storage conduit sized for use in the mouth of a human patient, the conduit having a proximal end, a distal end, and a bore having a central axis, the proximal end being closed by a movable powder dispensing actuator, the distal end being closed by an openable sealing nib that can be moved from its closed to its open position by force upon the actuator whether or not the distal end is in contact with a surface, the conduit containing finely-divided loosely-filled powdered sterile biomaterial and a plurality of powder-contacting clump-disrupting projections, the projections being arrayed inside and along the length of the conduit between the actuator and the nib and being movable in the direction of the central axis by force upon the actuator, wherein the device when held with its proximal end uppermost and the nib actuated to its open position provides a path along which powder falls past the projections and past the nib and is gravitationally dispensed from the device in non-aerosolized form.
