US 12,551,657 B2 · Custom length stylet

Abstract

A custom length stylet assembly for meeting medical device length tolerances. The custom length stylet assembly including a stylet wire having a length extending between a distal end and a proximal end, stylet handle defining a longitudinally oriented throughbore sized to retain a proximal portion of the stylet wire, the stylet handle further defining a proximately positioned track and tab, the track configured to retain a bent proximal end portion of the stylet wire, the length of the stylet wire selected during assembly of the stylet assembly to conform to the corresponding length of a body implantable lead within a predefined tolerance, the tab of the stylet handle melted into the track, thereby securely fastening stylet wire to the stylet handle to inhibit rotation or dislodgement.

Dependent claims

A method of assembling a stylet assembly comprising:

forming a stylet handle, the stylet handle defining a longitudinally oriented throughbore, a proximately positioned track, and a proximately positioned tab;
cutting a stylet wire to conform to a corresponding length of a body implantable lead within a predefined tolerance;
bending a proximal end portion of the stylet wire;
positioning the stylet wire within the longitudinally oriented throughbore defined in the stylet handle, such that the bent proximal end portion of the stylet wire is retained within the track and a distal portion of the stylet wire extends distally from a distal end of the stylet handle;
and
melting the proximately positioned tab of the stylet handle into the proximately positioned track, thereby securely fastening the stylet wire to the stylet handle and inhibiting rotation of the stylet wire relative to the stylet handle.
