  • Patent number: 11399844
    Abstract: A medical device holding assembly includes a carrier sheath, which carries an endoluminal medical device such as an embolization coil. The assembly also includes a housing including at least one holding element to hold the sheath, and a fixation device attached to the housing and coupled to the sheath. The fixation device includes a locking element having an unlocked configuration, which allows the sheath to slide relative to the housing, and a locked configuration, which fixes the sheath to the housing. A lock actuator is configured to lock permanently the locking element into the locked configuration. As a result, the sheath with the medical device held therewithin cannot be removed from the holding assembly during the deployment procedure, thereby ensuring that the procedure can be carried out by a single person and also protecting the integrity of the medical device before it is deployed into a patient.

  • Patent number: 11376114
    Abstract: A stent graft for deployment in a curved lumen such as the aortic or thoracic arch comprises a constraining mechanism at its proximal end. A stent provided at the proximal end of the stent graft includes loops of material that co-operate with restraining wires that extend between a central guide wire carrier and a restraining wire cannula. The constraining mechanism acts to maintain the proximal stent constrained at both the proximal and distal ends of the proximal stent. The proximal stent is thus allowed to expand after expansion of the remainder of the stent graft during deployment. In an embodiment, the constraining mechanism acts to constrain two adjacent struts of the proximal stent at three points radially therearound, at the proximal end of the stent and at the distal end of the stent. The proximal stent may then overlap with the interior of an adjacent stent at an inner part of a curved vessel.
