Abstract: A bicycle trailer is disclosed which can be reconfigured to act as a bicycle transport unit. When the trailer is in use towed behind a bicycle, its internal volume for receiving items to be transported is too small to accommodate a bicycle, even if the bicycle is broken down into its major parts. In accordance with the invention, the trailer has an internal frame (1 to 7), parts of which can be telescopically arranged in others to enable the frame to be enlarged or reduced in size, and an external shell (35, 36, 40) with foldable sections. The base of the frame (1) may have wheels (15, 17) enabling it to be rolled along when used as a carrying case. The trailer wheels (11) may be detachably mounted to either side of the frame base (1). A towbar (20) may be detachably fixed to the frame base (1).

Abstract: A method for synthesizing a primary amine, having the steps of: a) providing at least one dianhydrohexitol, and b) aminating the dianhydrohexitol by reacting same with ammonia, the amination being performed by heterogeneous catalysis using a hydrogenation catalyst in the presence of hydrogen.

Abstract: Embodiments of the invention provide a cannula having a body with a first outer diameter, a proximal end, a distal end, a lumen extending between the proximal and distal ends, and a portion outward of the first outer diameter having a second outer diameter greater than the first outer diameter that is adapted to space tissue from the fluid inlet to maintain fluid flow. Such a cannula is particularly useful for cardiopulmonary bypass procedures using a kinetically assisted venous drainage system.

Abstract: A cannula has a body with a proximal end and a distal end and a tip on the distal end. The tip has an outer wall defining a lumen opening at the end of the tip and extending to the proximal end of the cannula. The tip further comprises one or more ribs extending into the lumen to support the outer wall from kinking when the cannula is flexed. The outer wall has a inner surface defining the lumen and a plurality of non-circular apertures formed in the tip extending into the lumen. The apertures having a major axis and a minor axis. The major axis aligned in relation to a circumference of the outer wall to prevent puckering or buckling when the tip is bent. This alignment is also designed to support the outer wall from kinking when the tip is bent.

Abstract: A cannula has a body with a proximal end and a distal end. The body has a wall defining a lumen extending from the proximal end to the distal end, the lumen having a longitudinal axis. The cannula further has a plurality of apertures in the wall that are interconnected with the lumen, each of the apertures having a longer major axis and a shorter minor axis. The longer major axis of the apertures is perpendicular to the longitudinal axis of the lumen.
