Airless, non-clogging tip assembly and device

摘要

The invention described herein is a device (10) for dripping a tissue sealant and/or adhesive that comprises a) first and second barrels or syringes (12) that contain first and second biocomponents that are disposed between proximal and distal ends; b) a plunger (24) in each barrel and c) a drip tip comprising i) a support (68) having distal and proximal ends and at least two fluid passageways from the distal to the proximal end that are in fluid communication with one of the barrels of the dispensing device on the proximal end; and ii) an endcap (82) that fits over the support having at least two flexible flaps(83, 85). The present invention is also directed to an assembly for mixing and drip dispensing two reactive biologic components as tissue sealant and/or hemostatic agent and to methods for delivering biologic components to achieve hemostasis and/or tissue sealant by drip dispensing from the device described above.
