Publication number: 20210186812Abstract: A system is disclosed for recovering autologous thrombin from a blood product. The blood product is drawn into an injecting syringe and a clot is allowed to form. A discharge port of the injecting syringe is communicably connected to an intake port of an aspirating syringe through a hydrophilic filter assembly. The injecting and aspirating syringes are simultaneously operated to transmit blood product through the filter such that fibrous clotting material and red blood cells are removed by the filter and a concentrated, high-quality thrombin solution is recovered.Type: ApplicationFiled: December 15, 2020Publication date: June 24, 2021Inventor: Patrick Pennie

Patent number: 10987672Abstract: A dual piston centrifuge tube includes an elongate tubular receptacle having upper and lower ends interconnected by a sidewall. First and second common inlet/outlet ports are formed respectively in the upper and lower ends of the tubular receptacle. First and second liquid impermeable pistons are mounted within an interior chamber of the tubular receptacle for sliding longitudinally therein. The first piston is interconnected to the first port by a flexible fluid-conducting pipe that extends through the first piston to communicate with a region of the chamber between the first and second pistons. Blood or other biological fluid is introduced through the first port and pipe into the tubular receptacle to drive the first piston upwardly. The tube is centrifuged to separate the fluid into a plurality of constituent component levels between the first and second pistons. One of the layers is aspirated through the pipe and first port and re-introduced into the receptacle through the second port.Type: GrantFiled: June 8, 2018Date of Patent: April 27, 2021Assignee: Emcyte Corp.Inventor: Patrick Pennie

Patent number: 10537888Abstract: A centrifuge tube assembly includes an elongate tubular receptacle having upper and lower ends and a side wall that extends between the ends. A cap attached to the receptacle carries a common inlet/outlet port formed therethrough for communication with an interior chamber of the tubular receptacle. A liquid impermeable piston is longitudinally movable through the receptacle chamber and sealably interengages an interior wall of the receptacle. The piston separates upper and lower regions of the chamber, which respectively communicate with the inlet/outlet port and a pressure neutralizing vent. Biological products are introduced into and aspirated from the receptacle through the inlet/outlet port.Type: GrantFiled: May 23, 2019Date of Patent: January 21, 2020Inventor: Patrick Pennie

Publication number: 20090062741Abstract: A dual lumen syringe includes a body having a pair of elongate cavities or lumens formed therein. A directional valve is associated with each lumen. The valve is alternated between the first position wherein the lumen is communicably connected to a fluid inlet and a second position wherein the lumen is connected with a fluid outlet. There are a pair of elongate plungers, which are fixedly interconnected by a handle. Each plunger is received and longitudinally slidable in a reciprocating manner through a respective lumen. The valves are switched to a first position wherein the lumens are interconnected with the fluid inlets and the plunger is retracted to aspirate fluids through the respective inlets and into the lumens. The valves are then switched to a second position to communicably interconnect the lumens with the outlets.Type: ApplicationFiled: November 14, 2007Publication date: March 5, 2009Inventors: Emery Smith, Patrick Pennie, David K.
