Patent number: 10166332Abstract: The present disclosure relates to an apparatus for delivering a quantity of fluid to bone marrow. The apparatus may include a drive housing, a plunger operating assembly, a retractable sleeve, a first spring, a second spring, and a release mechanism. The drive housing may include a first portion configured to engage a driver assembly and a second portion configured to engage a cartridge assembly. The cartridge assembly may a fluid reservoir and a plunger assembly slidably disposed in the fluid reservoir. The cartridge assembly may be engaged with a bone penetrating needle and configured to rotate to insert the bone penetrating needle into the bone marrow. The first release mechanism may release the second spring to move the plunger operating assembly when the cartridge assembly is rotated to insert the bone penetrating needle into the bone marrow and the retractable sleeve is moved to a retracted position.Type: GrantFiled: March 8, 2016Date of Patent: January 1, 2019Assignee: TELEFLEX MEDICAL DEVICES S.À R.L.Inventors: Larry J. Miller, David S. Bolleter, Charles M. Schwimmer, Robert A. Wilk

Patent number: 10112979Abstract: Influenza viruses have traditionally been administered by intramuscular injection. The invention is based on the idea of using alternative routes of delivery for influenza vaccines, more specifically routes that do not require as large a dose of antigen. Delivery of influenza antigen to the Langerhans cells is the route of choice according to the invention. This route has been found to be particularly useful for vaccinating patients who are naïve to influenza virus (i.e. have not previously mounted an immune response to an influenza virus), which means that it is advantageous for immunising young children.Type: GrantFiled: March 30, 2015Date of Patent: October 30, 2018Assignee: Seqirus UK LimitedInventor: Derek O'Hagan

Patent number: 10092706Abstract: An autoinjector apparatus is disclosed which comprises a single-use cassette and an autoinjector. The cassette comprises a housing and a sleeve movably disposed in the housing. A syringe may be disposed in the sleeve and secured therein with a lock cap. The lock cap is affixed to a distal end of the sleeve and contacts the distal end of the syringe. A shield remover extends through an opening in a proximal end of the housing for removing a needle shield which covers a needle of the syringe. A cassette identification arrangement is provided on a surface of the housing to enable the autoinjector to identify the cassette. The autoinjector is provided with a detector for reading the cassette identification arrangement.Type: GrantFiled: April 20, 2012Date of Patent: October 9, 2018Assignee: AMGEN INC.Inventors: Michael Denzer, Robert W. Swift, Neal D. Johnston, Gabriele Ganzitti, Kenneth R. Ewing, Suhas Krishna

Patent number: 10065016Abstract: Systems and methods are disclosed herein that generally involve CED devices with various features for reducing or preventing backflow. In some embodiments, CED devices include a tissue-receiving space disposed proximal to a distal fluid outlet. Tissue can be compressed into or pinched/pinned by the tissue-receiving space as the device is inserted into a target region of a patient, thereby forming a seal that reduces or prevents proximal backflow of fluid ejected from the outlet beyond the tissue-receiving space. In some embodiments, CED devices include a bullet-shaped nose proximal to a distal fluid outlet. The bullet-shaped nose forms a good seal with surrounding tissue and helps reduce or prevent backflow of infused fluid.Type: GrantFiled: January 21, 2015Date of Patent: September 4, 2018Assignee: ALCYONE LIFESCIENCES, INC.Inventors: Deep Arjun Singh, Pj Anand, Blake Sama
