Patent number: 8790302Abstract: A syringe assembly includes a syringe barrel having an inside surface defining a chamber, an open proximal end, a distal end, and an outlet; a plunger assembly disposed at least partially within the syringe barrel, including an elongate plunger rod having a locking flange formed thereon; and a plunger head having a distal sealing surface, the plunger rod being engageable with the plunger head such that the plunger rod is adapted to move the plunger head within the chamber of the syringe barrel through an injection cycle; and a flange lock disposed at the open proximal end of the barrel. The flange lock is integral with the open proximal end of the syringe barrel. During the injection cycle, the flange lock engages the locking flange of the plunger rod so as to prevent removal of the plunger rod from the syringe barrel.Type: GrantFiled: July 27, 2011Date of Patent: July 29, 2014Assignee: Becton, Dickinson and CompanyInventors: Brian H.

Patent number: 8540670Abstract: A syringe assembly includes a syringe barrel having an inside surface defining a chamber and an outlet. A plunger assembly is disposed within the syringe barrel and includes an elongate plunger rod having a distal end surface, a plunger head having a distal sealing surface and a proximal end surface having a continuous perimeter, and a breakable neck portion integrally connecting the plunger rod and the plunger head. A retaining ring lock is disposed on the inside surface of the barrel and defines an engagement surface about a perimeter of the chamber. The retaining ring lock is adapted to engage and retain the plunger head in a locked position within the chamber. The engagement surface of the retaining ring lock engages the continuous perimeter of the proximal end surface of the plunger head in a perimetrical engagement when the plunger head is in the locked position.Type: GrantFiled: June 26, 2009Date of Patent: September 24, 2013Assignee: Becton, Dickinson and CompanyInventors: Brian H.

Patent number: 8075523Abstract: Various embodiments of syringe assemblies include a syringe barrel and a substantially conical tip or outlet disposed on the distal end of the barrel. The substantially conical tip includes a locking mechanism that engages an extension of a plunger assembly extending from a distal end of the plunger assembly so as to retain the extension within the substantially conical tip or outlet upon full injection of the contents of the syringe to a patient. According to one embodiment, a plunger head of the plunger assembly is slidably disposed on the extension. According to another embodiment, a separate hub, which holds a needle cannula, is disposed on an outlet at the distal end of the syringe barrel, which contains the locking mechanism. According to a further embodiment, the locking mechanism includes a locking clip disposed within the substantially conical tip of the syringe assembly.Type: GrantFiled: June 26, 2009Date of Patent: December 13, 2011Assignee: Becton, Dickinson and CompanyInventors: Brian H.

Patent number: 7972303Abstract: Syringe assemblies having a passive disabling system to prevent reuse are provided. In one embodiment, the passive disabling system activates after completion of an injection cycle. An exemplary syringe assembly incorporates a stopper and plunger rod attached in a manner to prevent users from disassembling the syringe prior to completion of the injection cycle. The barrel may also include an annular extension or collar that extends from the proximal end of the barrel. In a specific configuration, the annular extension at least partially envelopes a portion of the thumb press to prevent the user from accessing the thumb press and moving the plunger rod in a proximal direction Syringe assemblies of one or more embodiments also include visual indicators or markers indicating whether a syringe assembly is used or the plunger rod is locked within the barrel.Type: GrantFiled: June 12, 2008Date of Patent: July 5, 2011Assignee: Becton, Dickinson and CompanyInventors: Richard Caizza, Robert B.

Publication number: 20080262744Abstract: The present invention relates to systems and methods for tissue engineering. In particular, the invention is directed toward systems and methods for conditioning tubular biological structures. For example, an aspect of the present invention comprises systems and methods for uncoupling local mechanical parameters (e.g., circumferential stress, shear stress, and axial stress) from global mechanical parameters (e.g. lumen pressure, flow rate of perfusate, and longitudinal stretch of the construct) to control of local mechanical parameters for conditioning a tubular biological construct.Type: ApplicationFiled: April 18, 2008Publication date: October 23, 2008Applicant: Georgia Tech Research CorporationInventors: Brian H.
