Patent number: 10342966Abstract: A barrel adapter mountable to a syringe barrel includes a barrel tip, a needle assembly, a stylet assembly slidably disposed within a needle lumen of the needle assembly, and a plug within the lumen of the needle. An implant delivery syringe includes a barrel, a plunger assembly, and the barrel adapter. The syringe may include a needle retraction mechanism having a biasing member and an actuable locking arrangement. When the actuable locking arrangement is actuated, the biasing member causes the needle to axially translate over the stylet during retraction to dislodge the plug and cause delivery of an implant to a target location. The plug may be a biodegradable polymer plug such as a water-soluble polymer, PLGA, and/or CARP. The stylet may be retracted following delivery. Methods of assembling implant delivery syringes with drug implants are also provided.Type: GrantFiled: May 11, 2015Date of Patent: July 9, 2019Assignee: UNL Holdings LLCInventors: Gautam N. Shetty, Aaron M. Weir, Christian P. Brandt, Lou Castagna, Tod H. Brenner

Patent number: 10159808Abstract: A barrel adapter mountable to a syringe barrel includes a barrel tip, a biasing member, a locking mechanism, and a needle assembly. A safety syringe includes a barrel, a plunger assembly, and a barrel adapter. The needle assembly includes a needle, a needle hub, and a needle seal. The needle is configured to pass-through the needle assembly, locking mechanism, biasing member, and barrel tip such that, at one end the needle is within the barrel and at another end the needle passes through an aperture in the barrel tip. The barrel may be substantially cylindrical, having along its longitudinal axis a distal end for drug injection, a proximal end for injection control, and at least a portion of the barrel interior for drug containment. The barrel adapter provides needle retraction mechanisms to the barrel to form a safety syringe. Methods of assembling, manufacturing, and using such syringes are also provided.Type: GrantFiled: April 1, 2014Date of Patent: December 25, 2018Assignee: UNL Holdings LLCInventors: Masoud Samandi, Christian P. Brandt, Paul D. Goebel

Patent number: 9757527Abstract: Barrel adapters for safety syringes include a barrel and a plunger assembly adapted to move within the barrel, a barrel tip adapted to be sealingly engaged with a distal end of the barrel and a needle retraction mechanism barrel having a needle subassembly and an actuator subassembly. The needle subassembly includes a needle, and a needle-over-mold (NOM) through which the needle extends. The needle subassembly is disposed at least partially within the barrel tip, and adapted to move from an injection position in which the needle extends from a distal end of the barrel tip to a retracted position in which the needle is disposed within at least one of the barrel tip or the barrel. The actuator subassembly includes a needle seal, a push-bar, and an actuator surface. The needle retraction mechanism barrel includes a biasing member and an actuable locking arrangement. A syringe includes such barrel adapters.Type: GrantFiled: March 2, 2015Date of Patent: September 12, 2017Assignee: UNL Holdings LLCInventors: Kevin L. Bokelman, Eduardo Ho, Robert Scott Russo, Brandon J. McKee, John W. Carosi, Christian P. Brandt, Jyoti Gupta, Ramin Mojdehbakhsh

Publication number: 20150238745Abstract: A barrel adapter mountable to a syringe barrel includes a barrel tip, a needle assembly, a stylet assembly slidably disposed within a needle lumen of the needle assembly, and a plug within the lumen of the needle. An implant delivery syringe includes a barrel, a plunger assembly, and the barrel adapter. The syringe may include a needle retraction mechanism having a biasing member and an actuable locking arrangement, the locking arrangement initially maintains the biasing member in an energized position. When the actuable locking arrangement is actuated, the biasing member causes the needle to axially translate over the stylet during retraction to dislodge the plug and cause delivery of an implant to a target location. The plug may be a biodegradable polymer plug such as a water-soluble polymer, PLGA, and/or CAHP. The stylet may be retracted following delivery. Methods of assembling implant delivery syringes with drug implants are also provided.Type: ApplicationFiled: May 11, 2015Publication date: August 27, 2015Inventors: Gautam N. Shetty, Aaron M.
