Insert molded catheter puller member connectors and method of making the same

1. A method of securing a puller member in a control handle for a deflectable catheter, comprising:

preforming an end of the puller member;

placing the preformed end in an insert mold;

filling the insert mold with thermoplastic material to form a molded member; and

positioning the molded member encasing the end of the puller member in a control handle.

2. A method of claim 1 , further comprising shaping the thermoplastic material into a screw configuration.

3. A method of claim 2 , further comprising fastening the molded member to a wall in the control handle.

4. A method of claim 1 , further comprising:

joining the end of the puller member with an end of a second puller member; and

placing joined ends of the puller members in the insert mold.

5. A method of connecting two puller members of a deflectable catheter, comprising:

joining ends of the puller members to form a joined connection;

placing the joined connection in an insert mold; and

fill the insert mold with thermoplastic material to form a molded member.

6. A method of claim 5 , wherein the joined connection comprises:

a loop formed in the end of one puller member; and

a knot formed in the end of the other puller member.

7. A method of claim 6 , wherein the one puller member is a puller wire and the other puller member is a high modulus fiber material.

8. A method of claim 5 , wherein the joined connection comprises:

a coil formed in the end of one puller member; and

a knot formed in the end of the other puller member.

9. A method of claim 5 , wherein the one puller member is a puller wire and the other puller member is a high modulus fiber material.
