## Abstract

The present invention is directed to a method of securing a puller member in a control handle for a deflectable catheter. The method comprises 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. The method may also include shaping the thermoplastic material into a screw configuration and fastening the molded member to a wall in the control handle. The method may further include 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 2)

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

### Claim 4 (depends on 1)

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.

### Claim 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.

### Claim 6 (depends on 5)

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.

### Claim 7 (depends on 6)

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.

### Claim 8 (depends on 5)

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.

### Claim 9 (depends on 5)

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.
