Abstract

A strain relief device for use at a tube/hub junction of a tubular device such as a catheter. The strain relief device forms a lumen which may have a reduced diameter at a distal section thereof which can cooperate with the outer diameter of a catheter tube to form a wicking surface. The wicking cavity is formed to allow bonding material to be added thereto which, through capillary action, forms a uniform and controlled bond pattern between the strain relief device and the catheter tube. A catheter including the strain relief device of the invention is manufactured by inserting the strain relief device over a catheter tube/hub junction and permanently bonding the proximal end of the strain relief device to the hub in a conventional manner. The distal end of the strain relief device is then bonded to the catheter tube. The stain relief device of the present invention resists axial pulling forces, as well as bending forces, which may be applied to the catheter.
