Abstract: A container for storing a biological sample is disclosed. The container includes a first chamber having a sidewall extending between an open end and a closed end, defining a first chamber interior adapted to receive a sample holder therein. The container also includes a second chamber having a sidewall extending between an open end and a closed end, defining a second chamber interior adapted to subsequently receive the sample holder therein. The second chamber interior is in fluid isolation from the first chamber interior. A removable closure encloses at least one of the open end of the first chamber and the open end of the second chamber while the sample holder is disposed within one of the first chamber interior and the second chamber interior. A first fluid may be disposed within the first chamber interior, and a second different fluid may be disposed within the second chamber interior.

Abstract: A pressure sprayer includes an accumulator vessel adapted to hold a pressurized fluid therein and a container that is configured to hold a chemical concentrate. A motor in fluid communication with the accumulator vessel and the container is adapted to be driven by the pressurized fluid and to pump the pressurized fluid and the chemical concentrate. A chamber is adapted to receive the chemical concentrate and the pressurized fluid from the motor to form a chemical solution. A nozzle is in fluid communication with the chamber.

Abstract: A torque transducer assembly includes a first shell having a threaded neck and a distal end. A second shell is also provided. A sensor module includes a first frame member, a second frame member, and a sensor. The first frame member is attached to the first shell and the second frame member is attached to the second shell such that the first and second shells are coupled to one another. A method of manufacturing a torque transducer assembly is also provided. A packaging system including a torque transducer assembly is additionally provided.

Abstract: A packaging for an implantable medical device such as a heart valve wherein the implantable medical device is immersed in a liquid medium. The packaging comprises a jar and a lid assembly having a seal and a ridge therebetween, the ridge being adapted to contact the seal. At least one circumferential leg is interposed between the lid assembly and the jar. The leg maintains a predetermined spacing between the lid and the jar and may be loaded in compression. The lid assembly may comprise a lid and an overcap. The overcap may turn independently of the lid and may apply compressive pressure to the lid over the ridge and seal. The lid and overcap may be coupled together by, for example, mating snap hooks. At least one of the lid or overcap may have a plurality of snap hooks. At least one of the plurality of snap hooks may be of different length than other of the snap hooks, whereby an asymmetric force may be applied to the lid when the overcap is loosened from the jar.

Abstract: The present invention relates to an inventive non-elastomeric thermoplastic cap assembly that may be secured on an end of a generally cylindrical body at room temperatures. The cap is a deformable tubular sheath having an interior surface, an exterior surface, a first open end for receiving the end of the cylindrical body, and a second end which is at least partially closed to inhibit passage of the cylindrical body through the second end. The sheath has a gripping region adjacent the first open end to engage the exterior surface of the cylindrical body. The gripping region may include at least one ridge on the interior surface of the tubular sheath. The sheath also has a transition region adjacent the second end of the sheath, which helps the sheath provide a controlled and predictable amount of retention force over a wide range of component tolerances.

Abstract: The invention is a plunger useful in extruding or dispensing viscous material which comprises a thin disc of a material which is capable of deforming when subjected to back pressure during use. The edge of the disc has a circular shape and a cylindrical lip attached to the edge of the disc, which lip is disposed perpendicular to the edge of the disc. The disc has a face and a back surface located on opposite sides of the sheet. The disc also has a symmetrical convex portion which protrudes beyond the plane defined by the edge of the disc in the direction of the face and the peak of the convex portion disposed in the center of the disc. The disc further comprises a symmetrical concave portion which protrudes beyond the plane defined by the edge of the disc in the direction of the back surface. The concave portion of the disc surrounds the convex portion of the disc and the convex portion starts at the bottom of the concave portion.
