20090270816 | Even-Flow Multi-Stage Cannula - A single-lumen, multi-stage cannula particularly adapted for venous drainage during cardiac surgery includes a first stage comprising a longitudinal tubular tip having a first plurality of fenestrations to provide an axial flow at a proximal end of the tip. A second stage coaxial with the first stage comprises a nozzle section having an outer lumen wall and an inner annular wall. A central passage disposed within the inner annular wall continues the axial flow from the first stage. A plurality of outer passages is disposed between the outer lumen wall and the inner annular wall so that the inner annular wall isolates the central passage from the outer passages. The outer lumen wall includes a plurality of second fenestrations, wherein each second fenestration supplies fluid from a second region outside the cannula to a respective outer passage. The outer passages have respective outlets arranged to provide an injected flow substantially parallel to the axial flow. At least an initial portion of the central lumen of a proximal tube has an inside diameter greater than a diameter of the central passage. The central lumen continues the axial flow and receives the injected flow annularly injected around and substantially parallel with the axial flow. | 10-29-2009 |
20150320926 | VENTED CAP FOR CANNULA USED IN PERFUSION CIRCUIT - A removable cap for a cardiovascular cannula has a sleeve section with an inner surface adapted to receive a connector end of the cannula. The cap has a top section closing a closed end of the sleeve section. A pull tab extends radially from an open end of the sleeve section. A pair of tear seams are sunk into the sleeve section and the top section defining a tear strip in the cap. The sleeve section includes a segmented snap ring protruding radially inward on the inner surface of the sleeve section except at a pair of gaps coinciding with the pair of tear seams. The top section includes a seal cylinder projecting concentrically from the top section to seal against an inside surface of the cannula connector end. | 11-12-2015 |
