Patent number: 11565087Abstract: Catheter assemblies may include introducer needles having a notch or similar structure that allows flashback blood to enter the annular space between a catheter tube and an introducer needle of an IV catheter. The presence of flashback blood in this annular space can provide a clinician with an early, visible indication that a needle has entered a vein. The notch, however, may create a leak path for blood to escape outside of the catheter assembly, unless contained. Disclosed herein is a notch containment that prevents the notch from providing a leak path for blood to escape outside of the catheter during or after needle withdrawal.Type: GrantFiled: March 6, 2018Date of Patent: January 31, 2023Assignee: Smiths Medical ASD, IncInventors: Jay T Breindel, David J Goral, Christopher Roehl

Publication number: 20090082225Abstract: This invention is directed to a process for tightly binding nucleic acid to solid phase and corresponding processes for the utilization thereof. Nucleic acid is bound to solid phase matrices exhibiting sufficient hydrophilicity and electropositivity to tightly bind the nucleic acids from a sample. These processes include nucleic acid (double or single stranded DNA and RNA) capture from high volume and/or low concentration specimens, buffer changes, washes, and volume reductions, and enable the interface of solid phase bound nucleic acid with enzyme, hybridization or amplification strategies. The tightly bound nucleic acid may be used, for example, in repeated analyses to confirm results or test additional genes in both research and commercial applications. Further, a method is described for virus extraction, purification, and solid phase amplification from large volume plasma specimens.Type: ApplicationFiled: April 21, 2008Publication date: March 26, 2009Applicant: APPLERA CORPORATIONInventors: John C.
