Abstract
An implantable medical device for at least partially closing a neck portion of a vascular aneurysm is disclosed. The treatment device includes a collapsible neck bridge having a delivery configuration and a deployed configuration. The treatment device also includes an actuation mechanism operably attached to the collapsible neck bridge and configured to covert the collapsible neck bridge between the delivery configuration, wherein the actuation mechanism has an elongated form, and the deployed configuration, wherein the actuation mechanism has a constricted form.
Claims45
An aneurysm treatment device for at least partially closing a neck portion of a vascular aneurysm, comprising:
- a collapsible neck bridge having a delivery configuration and a deployed configuration;
- an actuation mechanism operably attached to the collapsible neck bridge and configured to convert the collapsible neck bridge between the delivery configuration, wherein the actuation mechanism has an elongated form, and the deployed configuration, wherein the actuation mechanism has a constricted form.
A method of treating an aneurysm in a parent vessel having a lumen, the aneurysm having a neck and inner wall defining a cavity that is in communication with the lumen, the method comprising:
- providing a collapsible neck bridge that incorporates an actuation mechanism and is detachably connected to a distal end of an elongated delivery member;
- endovascularly moving the collapsible neck bridge in a delivery configuration, wherein the actuation mechanism has an elongated form, to a site proximate the aneurysm;
- and
- actuating the actuation mechanism so as to covert the collapsible neck bridge from the delivery configuration to a deployed configuration wherein the actuation mechanism has a constricted form.
A system for treating an aneurysm in a vessel, the aneurysm having an inner wall and a neck defining a cavity, the system comprising:
- an elongated delivery member;
- a treatment device disconnectably attached to the elongated delivery member;
- and wherein
- the treatment device comprises a collapsible neck bridge that incorporates a constrictable actuation mechanism that has an elongated form and a constricted form, the collapsible neck bridge being in a delivery configuration when the actuation mechanism is in the elongated form, and in a deployed configuration when the actuation mechanism is in the constricted form.
