Abstract
Endoluminal filters are disclose with a first support member having a first end and a second end and a second support member attached to the first end of the first support member or the second end of the first support member. The filters also include a material capture structure extending between the first and second support members, a crossover between the first and second support members, and the first end or the second end of the first support member. The filters also include at least one tissue anchor with an elongate portion and a curved portion configured to engage with a lumen wall. The elongate portion has a length greater than a length of the curved portion. Methods for deploying and retrieving endoluminal filters are also disclosed.
Claims33
An endoluminal filter, comprising:
- a first support member having a first end and a second end;
- a second support member attached to the first end of the first support member or the second end of the first support member and forming a crossover with the first support member;
- a material capture structure extending between the first and second support members, the crossover, and the first end or the second end of the first support member;
- and
- at least one tissue anchor including an elongate portion and a curved portion, the curved portion configured to engage with a lumen wall, the elongate portion having a length of at least 25% of a length between the first end and second end of the first support member, the at least one tissue anchor formed on the first support member or the second support member.
An endoluminal filter, comprising:
- a first support member having a first end and a second end;
- a second support member having a first end and a second end forming a crossover with the first support member, the first end of the first support member attached to the first end of the second support member, the second end of the first support member attached to the second end of the second support member,
- the first support member and second support member defining a first loop structure and second loop structure, the first loop structure defined by the first end of the first support member, the first end of the second support member and the crossover, the second loop structure defined by the second end of the first support member, the second end of the second support member and the crossover;
- a material capture structure extending within the first loop structure;
- and
- a plurality of first tissue anchors including an elongate portion and a curved portion, the curved portion configured to engage with a lumen wall, the elongate portion having a length of at least 25% of a length between the first end and second end of the first support member, the plurality of first tissue anchors formed on the second loop structure.
