  • Patent number: 9867726
    Abstract: The invention relates to a device having an endovascular implant (1) for the introduction into blood vessels or body cavities of the human or animal body and an insertion aid (2), wherein the implant (1) and the insertion aid (2) being connected to each other via a detachment element (3) designed to be electrolytically corrodible so that after the implant (1) has been inserted into the body and a voltage has been applied an at least partial dissolution of the detachment element (3) takes place causing the implant (1) to be separated from its the insertion aid (3), with the detachment element (3) being made of a cobalt-chrome alloy containing at least 20% w/w cobalt and 10 to 40% w/w chrome.

  • Publication number: 20110238148
    Abstract: The invention relates to a device comprising an endovascular implant (1) to be introduced into blood vessels or body cavities of the human or animal body and an insertion aid (2), wherein the implant (1) and the insertion aid (2) being connected to each other via a detachment element (3) which is suitable to be dissolved at least partially after the device has been inserted into the body and in this manner causes the implant (1) to become detached or separated from the insertion aid (2), with said detachment element (3) being made of magnesium, a to magnesium alloy and/or a biodegradable material. Such a device enables particularly short detachment times to be attained.
