Publication number: 20200330690Abstract: A plunger stopper (12) configured for attachment with a plunger rod (14) for use with a within a syringe barrel for high dose accuracy drug delivery. The stopper having a first portion (40) formed from a first material and a second portion (42) formed from a second material, wherein the second material has a greater rigidity than the first material and wherein the second portion is configured to be attached to a plunger rod. The second material can be in the form of an insert (44) which functions to reduce the amount of distortion of the stopper during use, reduce air bubble size variation from fill to fill, maintain a seal with the inner wall of the syringe barrel with lower contact pressure in a resting state and reduce the amount of hysteresis of the stopper. The stopper can be adapted for use with infusers, pens, and other types of auto-injectors.Type: ApplicationFiled: May 14, 2019Publication date: October 22, 2020Inventor: Alfred W. Prais

Patent number: 5372945Abstract: Methods and apparatus for collecting and processing tissue to produce an endothelial cell product having a vessel for rinsing, draining, digesting and isolating tissue. The vessel has a rinsing and digesting chamber for containing tissue during processing. An inlet in the rinsing and digesting chamber allows entry of rinsing solution and tissue from a liposuction device. A waste chamber in fluid communication with the rinsing and digesting chamber preferably connects with a vacuum source. An isolation chamber is separated from the rinsing and digesting chamber by a screen. An ampule in fluid communication with the isolation chamber includes a pair of ports controlled by valve devices to be selectively in fluid communication with the isolation chamber. After processing, the ampule isolates a pellet of endothelial cells and the valve devices permit the pellet to be in fluid communication with the ports.Type: GrantFiled: July 31, 1992Date of Patent: December 13, 1994Inventors: Paul G.
