Abstract
A magnetic stylet includes a core element and a distal region. The core element may include a proximal end coupled to a tab, the proximal end having a first diameter, a transition region, and a distal region extending from the transition region to a distal end. The distal region may have a second diameter less than the first diameter. The distal section may include the transition region and the distal region of the core element, a magnetic element, a polymer member, and a closure element. The magnetic element may be positioned distal of the transition region of the core element. The polymer member may be circumferentially disposed about the distal region of the core element, the continuous permanent magnetic element, and at least a portion of the transition region of the core element. The closure element may be an epoxy that forms a rounded end distal of the polymer member.
