Title
(EN) SETTABLE AND UNSETTABLE DEVICE AND METHOD
(FR) DISPOSITIF ATTACHABLE ET DÉTACHABLE ET PROCÉDÉ
Abstract
(EN) A settable device including a radially enlargeable portion, a force retention pathway (between 20 and 42 or between 20 and 160) operably connected to the radially enlargeable portion to maintain a setting force to the radially enlargeable portion, a material disposed within the force retention pathway (between 20 and 42 or between 20 and 160) of the device, the material retaining force when in solid form and disengaging force retention when in fluid form.
(FR) La présente invention concerne un dispositif attachable comprenant une partie radialement extensible, un trajet de rétention de force (entre 20 et 42 ou entre 20 et 160) fonctionnellement relié à la partie radialement extensible pour maintenir une force d'attachement sur la partie radialement extensible, un matériau disposé dans le trajet de rétention de force (entre 20 et 42 ou entre 20 et 160) du dispositif, le matériau retenant la force lorsqu'il est sous forme solide et libérant la force de rétention lorsqu'il est sous forme de fluide.
