Patent number: 10441730Abstract: In one aspect, a pen needle assembly is provided herein which includes a hub, and a needle fixed to the hub, the needle having proximal and distal ends with a lumen extending therebetween. The needle extends distally from the hub to define an exposed length between the distal end of the needle and the hub in the range of about 5.0 to 9.0 mm. The hub defines a post formed about the needle, the post having a distally-facing first skin engaging surface. The exposed length of the needle extends distally from the first skin engaging surface. The hub also defines a distally-facing second skin engaging surface which at least partially circumscribes the first skin engaging surface. The second skin engaging surface being located proximally of the first skin engaging surface. Advantageously, a pen needle assembly is provided having two skin engaging surfaces which provide stability in achieving subcutaneous injections.Type: GrantFiled: February 4, 2014Date of Patent: October 15, 2019Assignee: Becton, Dickinson and CompanyInventors: Michael A.

Patent number: 10207053Abstract: In one aspect of the subject invention, a drug delivery device is provided which includes a reservoir for containing a medicament and has a proximal end and a distal end, the medicament including a suspension of solids in a liquid carrier. Further, the drug delivery device includes a needle in fluid communication with the reservoir and having a distal end for injection into a patient, and a proximal end in the reservoir. An accumulation surface is defined at least partially about the needle, distally of the proximal end of the needle. The accumulation surface defines a distally-extending indentation which is sized and shaped to collect, during use, solids that come out of suspension. Advantageously, with the subject invention, the accumulation surface allows for solids to accumulate at a location spaced from the proximal end of the needle, thereby minimizing the possibility of clogging the needle.Type: GrantFiled: March 16, 2012Date of Patent: February 19, 2019Assignee: Becton, Dickinson and CompanyInventors: Roger W. Groskopf, Lionel Vedrine

Patent number: 10124117Abstract: A drug delivery device is provided herein which includes a tubular body defining an opening. A drug cartridge is also provided having a distal end larger in diameter than the opening. With the drug cartridge being inserted into the tubular body in a use position, the distal end of the drug cartridge is located at least partially externally of the tubular body. The medical pen injector of the subject invention further includes an adaptor engageable with the body. The adaptor encompasses the distal end of the drug cartridge with the drug cartridge being in the use position. The adaptor includes features for mounting a needle assembly thereto. Advantageously, with the subject invention, a drug cartridge having a large distal end may be accommodated with a drug delivery device, e.g., a pen injector type device.Type: GrantFiled: May 5, 2009Date of Patent: November 13, 2018Assignee: Becton, Dickinson and CompanyInventors: Min Wei, Roger W.

Patent number: 8469923Abstract: A cartridge or injector for holding and mixing a medical product is provided herein including a tubular body having a cylindrical wall having first and second opposing ends. The wall includes inner and outer surfaces with the inner surface having a generally constant cross-section along at least a drug mixing area. A first stopper is slidably disposed within the wall between the first and second ends, the first stopper defining a liquid-tight seal with the inner surface. A second stopper is slidably disposed within the wall between the first stopper and the first end, the second stopper defining a liquid-tight seal with the inner surface. A flexible insert is disposed at or in proximity to the second end, the insert forming a liquid-tight seal with the wall, the insert being pierceable by a medical needle or other piercing instrument. A rigid retainer is fixed to the wall having an opening therein for providing access to the insert for piercing by a medical needle.Type: GrantFiled: September 29, 2008Date of Patent: June 25, 2013Assignee: Becton, Dickinson and CompanyInventors: Lionel Vedrine, Roger W.

Publication number: 20110092917Abstract: A drug delivery device is provided herein which includes a tubular body having a proximal end and a distal end, the tubular body defining an opening at or in proximity to the distal end, the opening defining an inner diameter. A drug cartridge is also provided having a proximal end, a distal end and a barrel portion disposed therebetween. The distal end of the drug cartridge is larger in diameter than the inner diameter of the opening. The drug cartridge is inserted into the tubular body to a use position by first inserting the proximal end of the drug cartridge into the opening. The distal end of the drug cartridge limits insertion of the drug cartridge into the tubular body due to the interengagement of the distal end of the drug cartridge and the tubular body. With the drug cartridge being in the use position, the distal end of the drug cartridge is located at least partially externally of the tubular body.Type: ApplicationFiled: May 5, 2009Publication date: April 21, 2011Applicant: BECTON, DICKINSON AND COMPANYInventors: Min Wei, Roger W.
