Publication number: 20180117261Abstract: A system for mixing drug products and injecting includes a syringe body, proximal and distal stopper members disposed in the syringe body, a plunger member, and a needle hub assembly coupled to the distal needle interface of the syringe body. The proximal and distal stopper members form a proximal drug chamber between there between and a distal drug chamber between the distal stopper member and a distal end of the syringe body. The plunger member includes a needle retention feature, an energy-storage member, and an energy-storage member latching member all disposed in disposed in a plunger interior. First and second sizes of the respective proximal and distal drug chambers can be modified by movement of the proximal and distal stopper members relative to the syringe body. The needle is at least partially retractable into plunger interior upon manipulation of the plunger member relative to the syringe body.Type: ApplicationFiled: November 1, 2017Publication date: May 3, 2018Applicant: Credence MedSystems, Inc.Inventors: Gary Steese-Bradley, Stephen H. Diaz, Alan E. Shluzas, John F. Shanley, Jeff Tillack, Dan Thayer, John Merhige

Patent number: 9919110Abstract: One embodiment is directed to a safety syringe system, comprising: an off-the-shelf syringe assembly comprising a syringe body and a plunger tip; a needle assembly removably coupleable to the distal end of the syringe body such that medicinal fluid may be transferred through a retractable needle coupled to a needle housing comprising the needle assembly upon insertion of the plunger tip relative to the syringe body; and a plunger control assembly coupled to the plunger tip and configured to facilitate manual insertion of the plunger tip relative to the syringe body; wherein upon insertion of the plunger tip to a final insertion state and release of an associated manual insertion load, the plunger tip may be proximally withdrawn, pulling the retractable needle proximally relative to the needle housing to a safe locked and retracted state wherein it is no longer exposed for injection.Type: GrantFiled: July 1, 2014Date of Patent: March 20, 2018Assignee: Credence MedSystems, Inc.Inventors: Stephen H. Diaz, John F. Shanley, Alan E. Shluzas, Jeff Tillack, Dan Thayer

Patent number: 9814843Abstract: One embodiment is directed to a method for safe injection, comprising: providing an injection assembly and inserting a plunger tip of the injection assembly to a final insertion state and releasing an associated manual insertion load. A retraction load developed sufficient to cause the plunger tip to be proximally withdrawn pulls the retractable needle proximally relative to the needle housing to a retracted state wherein a distal tip of the needle becomes mechanically locked into an encapsulated configuration wherein it is no longer exposed for injection.Type: GrantFiled: July 1, 2014Date of Patent: November 14, 2017Assignee: Credence MedSystems, Inc.Inventors: Stephen H. Diaz, John F. Shanley, Alan E. Shluzas, Jeff Tillack, Dan Thayer
