Patent number: 11931483Abstract: Inserts can be formed with elution characteristics to cause the inserts to elute an antimicrobial agent when subject to a fluid within a medical device. An insert can be formed with a desired geometry to allow the insert to be compression fit within a medical device to prevent the insert from moving or becoming dislodged once inserted into the medical device. The material may also be hygroscopic so that the insert swells when subject to a fluid thereby enhancing the compression fit of the device within the medical device. In some cases, the material can be reinforced using an internal structure. Inserts can be formed in many ways including by casting, thermoforming, or extrusion. In some cases, the inserts can be formed using a peel-away sleeve or material. The peel-away sleeves can be formed of a non-sticky material which facilitates removal of the inserts once the inserts have cured.Type: GrantFiled: August 27, 2020Date of Patent: March 19, 2024Assignee: Becton, Dickinson and CompanyInventors: Siddarth K. Shevgoor, Jonathan Karl Burkholz, Huibin Liu, Yiping Ma, Ming Zhou

Patent number: 10994118Abstract: Various embodiments of an antimicrobial stopcock medical connector is provided. More specifically, the present invention relates to a stopcock tap having fluid channels provided on portions of the outer surface of the stopcock tap, whereby fluid bypasses the stopcock through the fluid channels by flowing between the outer surface of the stopcock tap and the inner surface of the stopcock housing. Some embodiments further comprise an antimicrobial coating or insert that is provided in the one or more fluid channel, whereby fluid flowing through the fluid channels contacts the antimicrobial coating or an antimicrobial agent that is eluted from the antimicrobial coating. Further still, some embodiments of the present invention comprise an antimicrobial groove that is positioned opposite the fluid channel, whereby when the stopcock is in an “off” position, the antimicrobial groove contacts fluid within a blocked port thereby preventing microbial growth therein.Type: GrantFiled: November 8, 2018Date of Patent: May 4, 2021Assignee: Becton, Dickinson and CompanyInventors: Huibin Liu, Bryan Fred Bihlmaier, Janice Lin

Publication number: 20200353220Abstract: An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature protruding outwardly from the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.Type: ApplicationFiled: July 7, 2020Publication date: November 12, 2020Inventors: Jonathan Karl Burkholz, Bart D.
