摘要： A vascular occlusion device deployment system for placing an occlusion device at a preselected site within the vasculature of a patient. The deployment system employing a pusher having a lumen with an opening at the distal end of the pusher. A vascular occlusion device is connected to the distal end of the pusher by a portion that is removeably disposed within the opening. The portion of the occlusion device is forced out of the opening by an expandable reaction chamber, thereby deploying the occlusion device. The expandable reaction chamber, prior to deployment, has multiple chambers separated by a heat-dissolvable membrane. When the membrane is dissolved, components from the chambers react and expand, leading to deployment.

摘要： In one embodiment, a delivery system for a medical device includes a flexible sheath defining a lumen having a distal end and a flexible shaft having a proximal portion and a distal portion. A retention element and a pushing element, spaced proximally from the retention element, are disposed on the distal portion. The flexible shaft, retention element, and pushing element are disposable within the lumen. The flexible shaft is movable distally through the lumen between a stowed position and a deployed position and is movable proximally through the lumen between the deployed position and a partially deployed position with the retention element proximate to the distal end of the lumen. The retention element is configured to form with the medical device an interference fit with the flexible sheath when the flexible shaft is urged proximally from the retention position to engage the medical device with the flexible sheath.
