Publication number: 20260077173Abstract: A catheter cap includes a housing defining at least one cavity and an opening at a distal end of the housing, and an antimicrobial agent within the at least one cavity. The housing is configured to couple to a catheter luer at the distal end. The at least one cavity is configured to contain a catheter lock solution in contact with the catheter luer at the opening. The antimicrobial agent is present in an amount sufficient to maintain a minimum inhibitory concentration (MIC) of the antimicrobial agent in the catheter lock solution for a period of time between successive operations of the catheter luer.Type: ApplicationFiled: September 17, 2025Publication date: March 19, 2026Inventors: Valentino J. Tramontano, Genevieve L. Gallagher, Sean McDermott, Stephen W. Murray, David Thomashey, Kartik Sudhir Bondekar, Scott Jordan McDonald

Patent number: 11554247Abstract: A medical catheter assembly includes a catheter tip coupled to a distal end of an elongate catheter member and is symmetric about a plane defined by a septum of the elongate catheter member. The catheter tip defines first and second lumens, and the catheter tip defines first and second openings in the distal portion of the catheter tip. Each opening of the catheter tip is defined by a respective side surface of the catheter tip. Each opening is in fluid communication with a respective one of the first and second lumens of the catheter tip and with a respective one of a pair of lumens defined by the elongate catheter member. The distance between upper and lower surfaces of the catheter tip decreases from a distal end of the proximal portion toward a closed distal end of the catheter tip.Type: GrantFiled: October 30, 2019Date of Patent: January 17, 2023Assignee: COVIDIEN LPInventors: Marc Bellisario, David Thomashey
