20090216201 | Safety Needle Guard - A needle guard is disclosed. The needle guard includes a binding plate defining a multi-slot aperture adapted to receive a needle cannula therethrough. The needle guard also includes a biasing member for biasing the needle cannula within the multi-slot aperture, and a sensing arm connected to the binding plate. The sensing arm is adapted to contact a portion of the needle cannula, and is positionable for restricting movement of the needle cannula. The multi-slot aperture may include a first region having a first dimension, a second region having a second dimension, and optionally, a third region having a third dimension with the third dimension being smaller than the second dimension and the second dimension being smaller than the first dimension. | 08-27-2009 |
20090292259 | Stylet Handle Attachment Device - A hub assembly, such as for long needles, is disclosed. The hub assembly includes a needle hub having a proximal end and a distal end, having a cannula extending therethrough and protruding from the distal end, with the needle hub having a first engagement portion. The hub assembly also includes a stylet handle having a stylet extending therefrom. The stylet is adapted to be received within a portion of the cannula, with the stylet handle having a second engagement portion. Engagement of the first engagement portion of the needle hub and the second engagement portion of the stylet handle forms a positive lock in which at least a portion of one of the first and second engagement portions is held within the other of the first and second engagement portions in an unbiased state. | 11-26-2009 |
20090299400 | Safety stylet - A stylet for insertion within a cannula interior of a needle is disclosed. The stylet includes a solid elongated shaft having a proximal end adapted for engagement with a needle hub, and a distal end having a surface modified profile. The surface modified profile increases the penetration force required to penetrate human skin. The ratio of the penetration force of a stylet having an unmodified distal end to the stylet having a surface modified profile is at least 1:1.4, or greater. The surface modified profile may be a roughened surface, a buffed surface and/or a blunted surface. The surface modified profile may include a yieldable material disposed over at least a portion of the distal end. A needle assembly having a stylet having a surface modified profile is also disclosed. | 12-03-2009 |

20090112304 | METHOD FOR PERFORMING A VASCULAR ANASTOMOSIS - A method for performing a coronary artery bypass graft procedure on a patient to connect a bypass vessel to a target vessel includes the steps of creating an opening in the patient that communicates with the thoracic cavity of the patient; providing a bypass vessel having a lumen and at least one free end; passing the free end of the bypass vessel from the thoracic cavity through the opening to a position outside the body of the patient; attaching a connector to the free end of bypass vessel while the free end of the bypass vessel is outside the body of the patient; passing the free end of the bypass vessel from the position outside the body of the patient through the opening and into the thoracic cavity; and connecting the free end of the bypass vessel to a target vessel with the connector. | 04-30-2009 |
20100318038 | Syringe and Removable Needle Assembly Having Binary Attachment Features - A syringe and detachable needle assembly having binary attachment features include an elongate syringe barrel having a longitudinal axis, an open proximal end and an open distal end including a collar. The collar includes the cylindrically shaped sidewall having an inside surface and an outside surface. A needle assembly includes the hub having a body portion including a proximal end, a distal end and a conduit therethrough. A cannula having a distal end, a proximal end and a lumen therethrough is attached to the distal end of the hub so that the lumen is in fluid communication with the chamber. A lug is provided on one of the collar and the hub and a ramp and a rest surface is provided on the other of the collar and the hub. The ramp is oriented at an acute angle with respect to longitudinal axis for guiding the lug during needle assembly attachment, to the rest surface forcing the hub to contact the barrel to form a seal the hub and the barrel. | 12-16-2010 |

20100049143 | Detachable Needle Syringe Having Reduced Dead Space - A syringe and detachable needle assembly having reduced dead space features includes an elongate syringe barrel having open distal end including a collar and a distally facing annular surface projecting inwardly from the collar. A needle assembly includes a hub having a proximally facing annular surface and an outwardly projecting annular sealing ring positioned distally from the surface. The needle assembly also includes a cannula having a lumen therethrough connected to the distal end of the hub. Structure is provided for engaging the hub to the barrel resulting in the annular surface of the barrel contacting the annular surface of the hub to form a primary seal between said barrel and said hub and the annular sealing ring contacting the collar to form a secondary seal between the barrel and the hub. | 02-25-2010 |
20100314796 | Syringe and Removable Needle Assembly Having Binary Attachment Features - A syringe and detachable needle assembly having binary attachment features include an elongate syringe barrel having a longitudinal axis, an open proximal end and an open distal end including a collar. The collar includes the cylindrically shaped sidewall having an inside surface and an outside surface. A needle assembly includes the hub having a body portion including a proximal end, a distal end and a conduit therethrough. A cannula having a distal end, a proximal end and a lumen therethrough is attached to the distal end of the hub so that the lumen is in fluid communication with the chamber. A lug is provided on one of the collar and the hub and a ramp and a rest surface is provided on the other of the collar and the hub. The ramp is oriented at an acute angle with respect to longitudinal axis for guiding the lug during needle assembly attachment, to the rest surface forcing the hub to contact the barrel to form a seal the hub and the barrel. | 12-16-2010 |
20120296277 | Cutting Element For A Retracting Needle Syringe - A cutting element for a retracting needle syringe having a plunger with a cuttable distal end and a spring biased needle held by a cuttable support and a cutting element capable of cutting the cuttable distal end and the cuttable support includes a body portion having a proximal end, a distal end side wall therebetween and a passageway therethrough. The distal end of the body portion includes a cutting edge and a raised distally projecting tapered cutting tooth having distally converging edges. At least one tooth edge includes a sharp side wall for cutting the distal end of the plunger and the needle support. | 11-22-2012 |

20130139313 | Bassinet Rocking Device - An automatic bassinet rocking device imparts a rocking motion to a bassinet or rocking crib. A housing is supported above the rocker base of the bassinet on adjustable legs so that the device straddles the curved rocking base. A reciprocating rod descends from the housing and attaches to a strap or clamp at an anchor point on the rocker base. An oscillatory drive inside the housing imparts a reciprocating motion via the reciprocating rod onto the rocker base. | 06-06-2013 |

20110082437 | System and Method For Active Cooling of Stored Blood Products - A portable blood storage device includes an outer housing an inner housing. The outer housing defines the structure of the blood storage device. The inner housing is located within the outer housing and has an interior cavity for storing collected blood and/or blood components. The inner housing has an open top to allow access to the interior cavity. The storage device also has an inlet duct and a return duct located within the interior cavity. The inlet duct is fluidly connectable to a cooling device and brings conditioned air into the storage device when fluidly connected to the cooling device. The return duct is also fluidly connectable to the cooling device and returns exhaust air to the cooling device when fluidly connected. | 04-07-2011 |
