Patent

CA 2258046

A two-staged venous cannula is disclosed. The cannula includes an expandable reinforcing member around the atrial basket that prevents the cannula from kinking or collapsing in the area where the reinforcing member is applied. The reinforcing member preferably consists of an even number of rigid discrete beams of the same length equally spaced about the circumference of a cylinder. In an alternate embodiment, the beams may be equally spaced on the surface of a cone. Alternate spaces between the beams are formed. The alternate spaces between the beams are equally spaced around the circumference of the cannula. The alternate spaces between the beams remain equally spaced around the circumference of the cannula as the reinforcing member is expanded over a larger diameter. This design for the reinforcing member provides space between the beams where holes of the preferred shape, size and orientation can be placed through the cannula without requiring cutting through the material of the reinforcing member.

L'invention concerne une canule à deux étages. La canule comprend un élément de renforcement extensible tout autour du panier auriculaire, qui empêche la canule de se plier ou de s'écraser dans la zone où l'élément de renforcement est apposé. De préférence, l'élément de renforcement consiste en un nombre pair de baguettes rigides distinctes, de même longueur, et placées à intervalles réguliers tout autour de la circonférence d'un cylindre. Dans un autre mode de réalisation, les baguettes peuvent être placées à intervalles réguliers sur la surface d'un cône. Des espaces alternés sont formés entre les baguettes. Ces espaces alternés entre les baguettes sont eux-mêmes placés à intervalles réguliers tout autour de la circonférence de la canule. Les intervalles séparant lesdits espaces entres lesdites baguettes restent réguliers autour de la circonférence de la canule lorsque le diamètre de l'élément de renforcement est agrandi. Avec cette configuration, l'élément de renforcement comporte un espace entre les baguettes où des trous présentant la taille, la forme et l'orientation préférées peuvent être réalisés dans la canule sans qu'il faille couper dans la matière de l'élément de renforcement.
