Abstract
Implants and methods used for the treatment of aneurysms are disclosed. More particularly, embodiments of a vascular implant having several helical scaffolds, each helical scaffold including several undulations having short struts connected to long struts at an undulation joint, are disclosed. Other embodiments are also described and claimed.
Claims20
A vascular implant having an unexpanded state and an expanded state, the vascular implant comprising:
- a plurality of helical scaffolds winding around a longitudinal axis from a first end to a second end of the vascular implant, wherein each helical scaffold includes a terminal undulation at the first end and a plurality of medial undulations helically offset from the terminal undulation between the first end and the second end, wherein each medial undulation includes a short strut connected to a long strut by a medial joint, and wherein the short strut is at least 20% shorter than the long strut.
A vascular implant having an unexpanded state and an expanded state, the vascular implant comprising:
- a first helical scaffold winding around a longitudinal axis from a first end to a second end of the vascular implant, the first helical scaffold having a first terminal undulation at the first end and a plurality of medial undulations helically offset from the first terminal undulation between the first end and the second end, wherein each medial undulation includes a short strut connected to a long strut by a medial joint;
- and
- a second helical scaffold winding around the longitudinal axis from the first end to the second end, wherein a helical gap extends between the first helical scaffold and the second helical scaffold, and wherein a longitudinal distance across the helical gap is less than a difference in length between the short strut and the long strut.
