Abstract:
A method of manufacturing a hub assembly for a catheter tube having a lumen therethrough, comprising the step of:molding monolithically the hub assembly including a hub portion having a first rigidity, and a strain relief portion having a second rigidity less than the first rigidity to the catheter tube;the hub portion having a proximal end, a distal end, a wall, a connection disposed at the proximal end, and a lumen defined therethrough extending from the proximal end to the distal end;the strain relief having a proximal end, a distal end, and a wall, the strain relief being disposed at the distal end of the hub portion and the proximal end of the strain relief forming a continuous piece with the distal end of the hub portion, the strain relief defining a passage receiving the catheter tube such that the lumen through the hub portion is in fluid communication with the catheter lumen; andat least one groove extending into the strain relief wall, wherein the at least one groove extends through the wall into the passage.
