Abstract: A valve assembly for a medical device including a container including a first region and a second region, a first fluid inlet fluidly coupled to the first region, a second fluid inlet fluidly coupled to the second region, and a piston assembly disposed within the container. The container is configured to house an agent within the second region, the first fluid inlet is configured to deliver a first portion of pressurized fluid to the first region at a first pressure level, and the second fluid inlet is configured to deliver a second portion of pressurized fluid to the second region at a second pressure level that is less than the first pressure level. The piston assembly includes a valve configured to move from a first position to a second position in response to the piston assembly moving relative to the container.

Abstract: A system including variable parameter selection functionality operable for facilitating selection of a variable parameter of a composite query, parameter value assigning functionality operable for facilitating assignment to each parameter other than the variable parameter, one of the possible values associated therewith, composite query execution functionality operable, responsive to selection of the variable parameter and to assignment of the value to each parameter other than the variable parameter, for automatically executing the composite query for each possible value of the variable parameter, thereby being operable for receiving a multiplicity of composite query execution results corresponding to the multiplicity of possible values associated with the variable parameter, and composite query results display functionality operable, responsive to receiving the multiplicity of composite query execution results, for displaying, for each possible value associated with the variable parameter, a corresponding c

Abstract: This invention provides devices comprising substrates with wells for the patterning of particles or cells. Such devices are loaded with a suspension of particles or cell, and the entrapped particles or cells are transferred to a second substrate, where patterning of individual particles or cells occurs. Methods of cellular analysis, cell growth studies, surface modification, optical display fabrication and curved surface patterning using devices of this invention are described.
