    摘要： Trocar assembly embodiments are disclosed that include a trocar tube and a housing defining a chamber adjoining a proximal end portion of the trocar tube. An elastomeric seal member is positioned within the chamber for sealing the chamber as an elongate instrument passes through an opening formed in the seal member. A seal/protector assembly is positioned in the chamber proximally of the seal member in facing relationship to the seal member. The protector assembly includes at least two axially aligned protector members, each of which has an annular collar portion and at least one leaf portion formed integrally with the collar portion so as to form a living hinge portion. The leaf portions define an opening therethrough in axial alignment with the opening in the seal member. Insertion of an elongate instrument into contact with the leaf portions causes them to pivot distally increasing the size of the opening formed thereby permitting the instrument to pass therethrough and through the opening in the seal member without causing damage to the seal member.

    摘要： Cell co-culturing methods and arrays providing versatility and high resolution. A method comprising: providing at least one substrate; providing at least one first tip with at least one first cell-adhesion material disposed thereon, and at least one second tip with at least one second cell-adhesion material disposed thereon, wherein the first cell-adhesion material is different from the second cell-adhesion material; depositing the first cell-adhesion material from the first tip to the substrate to form at least one first deposit, and depositing the second cell-adhesion material from the second tip to the substrate to form at least one second deposit; and wherein the first and second deposits are capable of providing selective binding to at least one first cell so that the first cell selectively binds to the first deposit, and wherein the second deposit is capable of binding to at least one second cell.

    摘要： A venturi spray nozzle having a cleaning fluid manifold with a plurality of fingers extending into a plurality of venturi nozzle channels of an air manifold such that the air manifold educes cleaning fluid from the cleaning fluid manifold and projects it on a surface to be cleaned. The cleaning fluid manifold is centrally positioned in the air manifold and a pressurized source of cleaning fluid is used.
