Publication number: 20230263964Abstract: 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.Type: ApplicationFiled: February 15, 2023Publication date: August 24, 2023Applicant: Becton, Dickinsonand CompanyInventors: Christina D'Arrigo, Eric Schiller

Patent number: 9750529Abstract: 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.Type: GrantFiled: November 21, 2008Date of Patent: September 5, 2017Assignee: Becton, Dickinson and CompanyInventors: Annica Wayman, Michael Meehan, Christina D'Arrigo, Douglas Tyukody

Patent number: 9259553Abstract: 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. An 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.Type: GrantFiled: November 21, 2008Date of Patent: February 16, 2016Assignee: Becton, Dickinson and CompanyInventors: Peter George Delano, Andrew Wong, Michael Meehan, Christina D'Arrigo, Annica Wayman

Patent number: 8298180Abstract: 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.Type: GrantFiled: November 21, 2008Date of Patent: October 30, 2012Assignee: Becton, Dickinson and CompanyInventors: Michael Meehan, Christina D' Arrigo, Andrew Wong

Publication number: 20070129675Abstract: 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.Type: ApplicationFiled: December 5, 2005Publication date: June 7, 2007Applicant: Becton, Dickinson and CompanyInventors: Andrew Summerville, Jon Swenson, Christina D'Arrigo

Publication number: 20040002632Abstract: A suction device includes a suction cup having a vacuum inlet for connection to a vacuum source. The suction cup has a wall defining a cavity that is in fluid communication with the vacuum inlet and an engagement surface for engaging a tissue surface. The suction cup is formed of a material that minimizes injury to the tissue surface contacted by the engagement surface and tissue captured when the vacuum is applied and permits the captured tissue to be perfused during use of the suction device.Type: ApplicationFiled: November 7, 2002Publication date: January 1, 2004Inventors: Christina D'Arrigo, Daniel Gordon, John Matonick, David Stoloff, Rohit Tandon, Steven Zung-Hong Wu
