Abstract
Systems and methods for treating an aneurysm in accordance with embodiments of the present technology include intravascularly delivering an occlusive member to an aneurysm cavity and deforming a shape of the occlusive member via introduction of an embolic element to a space between the occlusive member and an inner surface of the aneurysm wall.
Claims19
A method for treating an aneurysm, the method comprising:
- positioning a distal end of an elongated shaft in an aneurysm cavity;
- releasing an occlusive member from the elongated shaft while the distal end of the elongated shaft is positioned within the aneurysm cavity such that the occlusive
- member self-expands to assume a first expanded state in which the occlusive member forms a first shape, wherein, in the first expanded state, the occlusive member encloses an interior region having a first interior volume;
- and
- delivering an embolic element between the occlusive member and the aneurysm wall to transform the occlusive member into a second expanded state in which the occlusive member encloses a second interior volume less than the first interior volume, wherein the occlusive member forms a second shape in the second expanded state that is different than the first shape in the first expanded state;
- and
- wherein transforming the occlusive member into the second expanded shape includes injecting the embolic element to invert a portion of a sidewall of the occlusive member such that the portion is convex towards the aneurysm wall in the first expanded state and concave towards the aneurysm wall in the second expanded state.
4 more elements
A method for treating an aneurysm, the method comprising:
- positioning an expandable occlusive member in an initial expanded state within an aneurysm, wherein in the initial expanded state the occlusive member provides a number of layers across a neck of the aneurysm;
- and
- doubling the number of layers of the occlusive member across the neck of the aneurysm by introducing an embolic element to an aneurysm cavity.
