The proximal end of the cannula is fixed to the distal end of the barrel. The cannula is positioned generally coaxially with the longitudinal axis. The hub is integrally formed with the distal end. The hub includes a rib section and a cap. The rib section has a generally cruciform cross-section taken along a rib plane. The rib plane is generally perpendicular to the longitudinal axis. The cap has a generally U-shaped cross-section taken along a longitudinal plane. The longitudinal plane is generally parallel to the longitudinal axis. | 01-12-2012 |
| 20110209410 | Barrier Isolator Port Assembly - A barrier isolator port assembly for connecting to a conventional docking port of an isolated enclosure is provided. The port assembly includes an annular body, a door assembly and a lock. The annular body is configured to engage a docking port of the isolated enclosure. The port assembly also includes a door assembly mountable within the annular body and a lock operatively connected to the annular body. The lock includes a lever and a pin. The lever is pivotably connected to the annular body about a pivoting member and configured to pivot about the pivoting member to removably insert the pin into the recess of the door assembly. | 09-01-2011 |

| 20110034879 | Automatic Injection Mechanism with Frontal Buttress - The present invention provides for an autoinjector that registers off a distal end of a syringe to provide for a more accurate needle insertion depth. The autoinjector employs an automatically deployable frontal buttress for registration of the distal end or shoulder of the syringe. | 02-10-2011 |
| 20100331465 | TPE COMPOSITION HAVING GOOD CLARITY AND LOW HARDNESS AND ARTICLES FORMED THEREFROM - A thermoplastic elastomer (TPE) composition is provided which has a first high vinyl styrenic block copolymer (SBC) having a number average molecular weight (Mn) less than about 120,000 Daltons (Da) and a second high vinyl SBC having a Mn greater than about 120,000 Da; a polyolefin; and a plasticizer compatible with the first and second SBCs. An article formed from such a TPE composition has a tensile strength greater than 600 psi, a hardness less than 45 Shore A, and a haze less than 20 percent, preferably less than 15 percent, when the thickness of the article is 1.7 mm, and wherein the physical dimensions of the article remain substantially unchanged after immersion of the article in boiling water for one hour. | 12-30-2010 |
| 20100270702 | COLLET MECHANISM AND METHOD OF MOLDING CANNULA TO A SYRINGE BARREL - A collet mechanism that holds a cannula during molding of a syringe includes first and second arms that form an internal cavity. Each arm has a proximal end and a distal end. The first and second arms are in a closed position when the distal ends are moved toward the internal cavity and are in an open position when the distal ends are positioned away from the internal cavity. First and second cannula guides respectively are mounted proximate the distal ends of the first and second arms and extend into the internal cavity. The first and second cannula guides clamp a portion of the cannula to hold the cannula when the first and second arms are in the closed position. | 10-28-2010 |
| 20100185148 | Injector Apparatus - The present invention provides an injector apparatus suitable for use with an automatic injection device. The injector apparatus includes a cylindrical housing having a deflectable member and a removable guard. The deflectable member releasably holds a syringe tube assembly in the axial direction when the apparatus is in the initial position. Then, after use, the deflectable member provides a tamper evidence means for indicating whether or not the injector apparatus was previously used or tampered with. | 07-22-2010 |
| 20090288977 | Vacuum Package System - A vacuum packaging system for transporting a plurality of medical containers includes a plurality of medical a tray that receives and supports the medical containers. The tray includes opposing first and second side walls, opposing side and rear walls and a bottom floor. The walls extend generally perpendicularly from the bottom floor of the tray to a top edge thereof. A nesting plate is removably mountable in the tray and includes a plurality of generally cylindrical sleeves each receiving one of the plurality of medical containers. A support surface within the tray generally extends parallel to and spaced a predetermined distance from the bottom floor of the tray and receives and supports the nesting plate. An air impervious flexible film defines an internal cavity and completely surrounds the tray and the medical containers. The internal cavity is evacuated to and maintained at a predetermined vacuum level below atmospheric pressure. | 11-26-2009 |
| 20090118676 | SAFETY NEEDLE - A packing sleeve for use with a safety needle that automatically covers a tip of a needle following removal of the needle from a patient includes a generally hollow body having a longitudinal axis and a distal end and an open proximal end. The body surrounds at least a portion of the safety needle and has at least one track having an activation leg and a releasing leg. The at least one track is in sliding engagement with at least one member of the safety needle such that the motion of a portion of the safety needle relative to the body is dictated by a path the at least one member follows along the respective at least one track. The safety needle is in an initial position when the at least one member is proximate a first end of the activation leg and in an intermediate position when the at least one member is proximate a second end of the activation leg. The releasing leg extends from the second end of the activation leg and allows the at least one member to be slid toward and then removed from the proximal end of the body. | 05-07-2009 |
| 20090100802 | VACUUM PACKAGE SYSTEM - A vacuum packaging system for transporting a plurality of medical containers includes a plurality of medical containers each having a head side and a base side and a tray that receives and supports the medical containers. The tray includes opposing first and second sidewalls, opposing front and rear walls and a bottom floor. The walls extend generally vertically from the floor of the tray. At least one platform generally extends parallel to the floor of the tray. An air impervious flexible film defines an internal cavity. The air impervious flexible film completely surrounds the tray and the medical containers and the internal cavity is evacuated to and maintained at a predetermined vacuum level below atmospheric pressure. One of the head side and the base side of each medical container contacts a top surface of at least one platform when the medical containers are positioned in the tray. | 04-23-2009 |
| 20080249477 | PEN INJECTOR HAVING A NEEDLE SHIELD - A pen injector includes a vial cartridge and a generally tubular body that surrounds the vial cartridge. A needle shield assembly is removably mounted to a mounting end of the body and includes a hollow needle that has a tip for injecting into a patient. A needle hub at least partially surrounds the hollow needle and a slideable sleeve is slideably mounted on the needle hub. The needle hub has an outer surface which deflects the slideable sleeve as the slideable sleeve slides toward a receiving end of the needle hub and into a retracted position. The slideable sleeve bears resiliently on the outer surface of the needle hub during sliding movement of the slideable sleeve relative to the needle hub toward the retracted position such that a restoring force is generated for urging the slideable sleeve to move toward an injection end of the needle hub and into an extended position in which the tip of the needle is located completely inside of the slideable sleeve. | 10-09-2008 |
