Publication number: 20150164523Abstract: A clot retrieval device 1 for removing occlusive clot from a blood vessel, the device comprises an inner elongate body 3 having a collapsed delivery configuration and an expanded deployed configuration and an outer elongate body 2 at least partially overlying the inner elongate body 2. The outer elongate body 2 is expandable to a radial extent which is greater than the radial extent of the inner body 3 in the deployed configuration to define a clot reception space 11. The outer elongate body 2 comprises a distal end portion 24,49 and the inner elongate body 3 comprises a main body portion 10 and a distal portion which extends in the deployed configuration towards the outer elongate body 2 to a greater extent than the main body portion.

Patent number: 8251099Abstract: A check valve in particular for medical applications has a first hose connecting casing and a second hose connecting casing and a membrane disk configured between the two hose connecting casings. The membrane disk is made of a resilient material and cooperates with an annular valve seat. The membrane disk is fitted radially outside the valve's seat with apertures leading to a discharge space. The wall of the second hose connecting casing is opposite the apertures and fitted with a surface curved away from the membrane toward the discharge channel. The discharge channel is fitted with an intake mouth in the wall, and conically tapers within a transition segment toward the intake mouth. Recesses communicating with the discharge space are fitted into the transition segment and are dimensioned in a way to substantially compensate the different flow cross-sections between the intake mouth and the discharge channel.Type: GrantFiled: January 22, 2009Date of Patent: August 28, 2012Assignee: Illinois Tool Works Inc.Inventors: Colm Carmody, Kieran Costello, Brendan Casey
