Abstract: A biomaterial delivery device includes an elongated handheld powder storage conduit with proximal and distal ends and a bore having a central axis. The proximal end is closed by a movable powder dispensing actuator, and the distal end is closed by an openable sealing nib moveable from its closed to its open position by force upon the actuator. The distal end has a distally-projecting powder discharge chute that spaces the nib away from a surgical site. When the device is held upright over a surgical site with the nib opened, powder passing the nib is deflected at a first oblique direction with respect to the central axis and into or onto the powder discharge chute, and powder striking the chute is deflected at a rotationally distinct second oblique direction orientation with respect to the central axis and into or onto the surgical site.

Abstract: A catheter configured with an elongate tube and a diffuser is disclosed. The diffuser may be configured to facilitate high flow rates through the catheter and to resist blockage of openings disposed within the body. Further, the catheter may be comprised of flexible materials to facilitate delivery into and removal from the body. In some embodiments the diffuser may be generally disc shaped.
