Publication number: 20230143477Abstract: A subcutaneous port assembly includes a base, a connector, a stem, a sealing element, and a locking member. The connector extends from a first end attached to the base to a distal end and includes an inner surface defining a socket having an inside diameter. The stem extends from the base and into the socket. The stem includes an outer surface having an outside diameter that is less than the inside diameter of the socket. The sealing element is disposed within the socket between the stem and the inner surface of the socket. The locking member has a plunger received within the socket from the distal end and having a terminal end facing the sealing element. The plunger is axially movable between a first position and a second position to selectively compress the sealing element within the socket.Type: ApplicationFiled: April 2, 2021Publication date: May 11, 2023Applicant: Takeda Pharmaceutical Company LimitedInventors: Ayesha Arzumand, Chris Tarapata, Marc Bellisario, Christel Hartshorn, Matthew J.

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

Patent number: 9468461Abstract: The present disclosure relates to catheterization systems and components thereof. In one embodiment of the present disclosure, a catheterization system is disclosed that includes a catheter including a body with proximal and distal ends and defining first and second lumens extending therethrough, and a stylet. The stylet includes first and second stylet portions each having proximal and distal end regions, wherein the distal end regions of the first and second stylet portions together define a tapered penetrating portion. The first and second stylet portions are configured and dimensioned to be slidably positioned within the first and second lumens of the catheter, respectively. The first and second stylet portions extend from the proximal end of the catheter and beyond the distal end of the catheter, and are independently movable in relation to each other to facilitate selective removal of the first stylet portion and/or the second stylet portion from the catheter.Type: GrantFiled: June 3, 2013Date of Patent: October 18, 2016Assignee: Covidien LPInventors: Marc Bellisario, Mark Lotito, Kurt E.

Publication number: 20100168718Abstract: An extension tube assembly for fluidly connecting a catheter assembly to a hemodialysis machine includes an extension tube member and a coupling mechanism. The extension tube member includes first and second extension segments. The first extension segment is adapted for connection to a catheter hub and defining a first lumen. The second extension segment is adapted for fluid connection to a hemodialysis machine and defining a second lumen. The coupling mechanism is adapted to connect the first and second extension segments to establish fluid communication between the first and second lumens. The coupling mechanism includes a first coupling mounted on a distal end of the first extension segment and a second coupling mounted on a proximal end of the second extension segment. The first and second couplings cooperate to provide a releasable connection therebetween to permit selective connection and disconnection of the first and second extension segments.Type: ApplicationFiled: December 11, 2009Publication date: July 1, 2010Applicant: Tyco Healthcare Group LPInventors: Marc Bellisario, Mark Lotito
