Abstract
A urinary catheter is disclosed. The urinary catheter comprises a catheter tube having a proximal insertion end and a distal end. The catheter also comprises a drainage member. The drainage member includes a wall having an inner surface and an outer surface. The inner surface defines a drainage lumen having an opening in a proximal end of the drainage member. The distal end of the catheter tube is inserted through the opening of the proximal end of the drainage member and is located in the lumen. The wall of the drainage member has at least one window therethrough. The drainage member and the catheter tube are welded to one another at one or more welding sites in the vicinity of the window(s).

A urinary catheter, comprising:
- a catheter tube having a proximal insertion end and a distal end;
- a drainage member including a wall having an inner surface and an outer surface, the inner surface defining a drainage lumen having an opening in a proximal end of the drainage member;
- the distal end of the catheter tube being inserted through the opening of the proximal end of the drainage member and located in the lumen, the wall of the drainage member having an outer surface that includes a recess, a plurality of windows through the wall of the drainage member and being located in the recess, wherein the drainage member and the catheter tube are welded to one another at the plurality of windows.
A urinary catheter, comprising:
- a catheter tube having a proximal insertion end and a distal end;
- a drainage member including a wall having an inner surface and an outer surface, the inner surface defining a drainage lumen having an opening in a proximal end of the drainage member;
- the distal end of the catheter tube being inserted through the opening of the proximal end of the drainage member and located in the lumen, the wall of the drainage member having at least one window therethrough, wherein the drainage member and the catheter tube are welded to one another at a site of the window(s);
- and
- a gripper for gripping the catheter tube when using the urinary catheter, wherein the gripper is releasably attached to the drainage member.
