Patent number: 9474868Abstract: A single-use syringe assembly is disclosed which includes a syringe body defining a fluid reservoir and including an engagement surface, a plunger assembly including a plunger rod and a sealing member supported on a distal end of the plunger rod, and a releasable member having a proximal end releasably positioned within a sealing member throughbore and a distal end configured to engage the engagement surface of the syringe body when the sealing member is moved to the advanced position. The proximal end of the releasable member being configured to seal the sealing member throughbore. The releasable member is configured such that a force required to remove the distal end of the releasable member from engagement with the engagement surface of the syringe body is greater than the force required to disengage the proximal end of the releasable member from the sealing member throughbore.Type: GrantFiled: March 23, 2009Date of Patent: October 25, 2016Assignee: Covidien LPInventors: Christopher Buder, Kurt E. Green

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. Green, Geoffrey McElroy

Patent number: 8876801Abstract: A valve assembly is provided which includes a housing having an inlet end and an outlet end and defining a fluid channel and a central chamber. A dissolvable valve member is positioned to obstruct flow through the channel within the chamber. The dissolvable valve member is formed of a material which is dissolvable at a predetermined rate upon contact with a preselected fluid. The preselected fluid is selected from the group consisting of blood, urine, saline and antimicrobial solutions. The dissolvable valve member can be formed from a fluid soluble glass or a starch based material.Type: GrantFiled: July 1, 2013Date of Patent: November 4, 2014Assignee: Covidien LPInventor: Kurt E. Green
