Definitions

  • cam 58 may rotate in correspondence with the first actuation of plunger actuator 54 by rotating in a clockwise direction, and cam 58 may rotate in correspondence with the second actuation of plunger actuator 54 by rotating in a counter-clockwise direction.
  • Cam 58 may be operably coupled to a proximal end 72 of plunger 52.
  • a portion 74 of cam 58 may be in contact with proximal end 72.
  • a cross-section of shaft 44 transverse to a longitudinal axis 88 of shaft 44 may be concave such that at least a portion of a longitudinal surface of plunger 52 is exposed.
  • This configuration may allow IMD 16 to engage engagement mechanism 62 while at least a portion of IMD 16 is disposed outside of shaft 44, which may advantageously facilitate implantation of IMD 16.
  • at least a portion of IMD 16 being disposed outside of shaft 44 may increase the reliability of releasing and implanting IMD 16.
  • plunger 52 may exert a contact force on IMD 16 exceeding a reaction force of engagement mechanism 62 such that engagement mechanism 62 and engagement feature 92 separate (e.g., protrusions 64 are no longer disposed within first recess 96 and second recess 100).
  • plunger 52 may exert the contact force in response to the first actuation of plunger actuator 54, which as noted above may correspond to moving plunger actuator 54 in a substantially proximal direction.

Abstract

L'invention concerne un outil composé d'une poignée, d'un actionneur de piston situé à proximité de la poignée (42), d'une tige (44) se déployant depuis la poignée, d'un piston (52) et d'un mécanisme de mise en prise. La tige comprend une extrémité proximale et une extrémité distale, et définit un canal qui se déploie sur toute sa longueur. Un premier actionnement de l'actionneur de piston entraîne la translation du piston sur la longueur de la tige dans une direction distale. Un second actionnement de l'actionneur de piston entraîne la translation du piston sur la longueur de la tige dans une direction proximale. Le mécanisme de mise en prise est disposé à l'extrémité distale et est configuré pour mettre en prise un dispositif médical implantable (16) et libérer le dispositif médical implantable lorsque le piston exerce une force de contact sur le dispositif médical implantable supérieure à une force de réaction du mécanisme de mise en prise lorsque le piston se déplace sur la longueur de la tige dans la direction distale.
