Abstract
A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.
Claims17
An intravascular tack, comprising:
- a self expandable tubular body, having a proximal end, a distal end and a central lumen extending therethrough, the body comprising a plurality of metal struts and having a length of no more than about 15 mm;
- wherein the tubular body is radially expandable through a range of diameters which range exceeds 3 mm and the change in radial force upon expansion is no more than about 2.5 N at any point in the range.
-7. (canceled)
A formed in situ intravascular construct, comprising a plurality of at least three intravascular tacks each having a length of no more than about 8 mm and spaced apart from an adjacent tack by at least about 2 mm, each tack having a radial expansion force of no more than about 4 N.
-14. (canceled)
An endoluminal staple, comprising:
- a first circumferential member disposed at a proximal end or a distal end of the endoluminal staple, the first circumferential member having a first outward apex disposed between first and second struts, a second outward apex disposed between third and forth struts, a first inward apex disposed between the second and third struts, and a second inward apex disposed adjacent to the fourth strut;
- a second circumferential member disposed adjacent to the first circumferential member;
- and
- a bridge member having a first end coupled with the second inward apex and a second end coupled with the second circumferential member, the bridge member having an anchor disposed thereon;
- wherein the staple has a compressed state for delivery and an expanded state, the staple being configured such that in the expanded state, a first angle defined at the first outward apex between the first and second struts is different from a second angle defined at the second outward apex between the third and fourth struts, the first and second angles configured to control force distribution in the struts.
