Abstract
An example occlusive implant is disclosed. The example occlusive implant includes an expandable framework configured to shift between a collapsed configuration and an expanded configuration, wherein the expandable framework includes a plurality of strut members circumferentially spaced around a longitudinal axis of the expandable framework, wherein one or more of the plurality of strut members includes a first twisted portion and a face portion. The occlusive implant also includes a plurality of fixation members disposed along the face portion of one or more of the plurality of strut members.
Claims20
An occlusive implant, comprising:
- an expandable framework configured to shift between a collapsed configuration and an expanded configuration, wherein the expandable framework includes a plurality of strut members circumferentially spaced around a longitudinal axis of the expandable framework, wherein one or more of the plurality of strut members includes a first twisted portion, a second twisted portion, and a face portion extending therebetween, wherein in the expanded configuration, an entirety of the face portion extends linearly between the first twisted portion and the second twisted portion;
- and
- a plurality of fixation members disposed along the face portion of one or more of the plurality of strut members;
- wherein in the collapsed configuration, a first plurality of fixation members disposed along a first face portion are longitudinally offset and circumferentially interdigitated with a second plurality of fixation members disposed along an adjacent second face portion.
An occlusive implant, comprising:
- an expandable framework configured to shift between a collapsed configuration and an expanded configuration, wherein the expandable framework includes a plurality of strut members circumferentially spaced around a longitudinal axis of the expandable framework, wherein one or more of the plurality of strut members includes a first twisted portion, a second twisted portion, and a face portion extending therebetween, wherein in the expanded configuration, an entirety of the face portion extends linearly between the first twisted portion and the second twisted portion;
- a plurality of fixation members disposed along the face portion of one or more of the plurality of strut members, each fixation member having a first end fixed to the strut member and a second free end extending radially away from the strut member;
- and
- an occlusive member disposed along an outer surface of the expandable framework;
- wherein in the collapsed configuration, a first plurality of fixation members disposed along a first face portion are longitudinally offset and circumferentially interdigitated with a second plurality of fixation members disposed along an adjacent second face portion.
An occlusive implant, comprising:
- an expandable framework configured to shift between a collapsed configuration and an expanded configuration, wherein the expandable framework includes a plurality of strut members circumferentially spaced around a longitudinal axis of the expandable framework, wherein some of the plurality of strut members include a first twisted portion, a second twisted portion, and a face portion extending therebetween, wherein in the expanded configuration, the first and second twisted portions on a first strut member twist in a first direction, and the first and second twisted portions on a second strut member twist in a second direction opposite the first direction, wherein the first and second strut members are adjacent one another;
- and
- a plurality of fixation members disposed along the face portion of one or more of the plurality of strut members.
