Curved catheter and methods for making same

A method for curving a catheter tube of a catheter assembly, the catheter assembly comprising a bifurcation hub including a tube constraint, the method comprising:

• constraining the catheter tube into a curved configuration by coupling the catheter tube to the bifurcation hub;
• heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature;
• and
• releasing the catheter tube from the tube constraint after the heating is complete, wherein the catheter tube permanently retains the curved configuration.

A method for curving a catheter tube of a catheter assembly, the catheter assembly including a tube constraint comprising a suture wing, the suture wing including a notch designed to constrain the catheter tube, the method comprising:

• constraining the catheter tube into a curved configuration by inserting the catheter tube into the notch of the suture wing;
• heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature;
• and
• releasing the catheter tube from the tube constraint after the heating is complete, wherein the catheter tube permanently retains the curved configuration.

A method for curving a catheter tube of a catheter assembly, the catheter assembly including a tube constraint comprising a suture wing including a clip designed to constrain the catheter tube, the method comprising:

• constraining the catheter tube into a curved configuration by inserting the catheter tube into the clip of the suture wing;
• heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature;
• and
• releasing the catheter tube from the tube constraint after the heating is complete, wherein the catheter tube permanently retains the curved configuration.

A method for curving a catheter tube of a catheter assembly, the catheter assembly including a tube constraint comprising a spun-bonded olefin sheet including one or more openings designed to receive the catheter tube, the method comprising:

• constraining the catheter tube into a curved configuration by inserting the catheter tube into the one or more openings of the sheet;
• heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature;
• and
• releasing the catheter tube from the tube constraint after the heating is complete, wherein the catheter tube permanently retains the curved configuration.

A method for curving a catheter tube of a catheter assembly, the catheter assembly including a tube constraint, the method comprising:

• constraining the catheter tube into a curved configuration by inserting a portion of the catheter tube in at least one notch provided on the catheter assembly;
• heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature;
• and
• releasing the catheter tube from the tube constraint after the heating is complete, wherein the catheter tube permanently retains the curved configuration.
