Tubular filter
First Claim
1. A method of preparing a filter for delivery into a body vessel, the filter comprising a first, second, third, fourth, fifth, and sixth anchor member arranged successively counterclockwise about a circumference of the hub when viewed from a distal end of the filter, each anchor member including either a cranial extension or a caudal extension at a distal end thereof, the filter further comprising a first, second, third, fourth, fifth, and sixth locator member arranged successively counterclockwise about a circumference of the hub when viewed from the filter distal end, each locator member extending from the hub between an adjacent pair of anchor members, the method comprising:
- (i) constraining the anchor members in a collapsed configuration;
(ii) positioning a length of the first locator member closest clockwise of the first anchor member behind the first anchor member and the second anchor member such that a distal end of the first locator member extends between the second anchor member and the third anchor member;
(iii) positioning a length of the second locator member behind the second anchor member and the third anchor member such that a distal end of the second locator member extends between the third anchor member and the fourth anchor member;
(iv) positioning a length of the third locator member behind the third anchor member and the fourth anchor member such that a distal end of the third locator member extends between the fourth anchor member and the fifth anchor member;
(v) positioning a length of the fourth locator member behind the fourth anchor member and the fifth anchor member such that a distal end of the fourth locator member extends between the fifth anchor member and the sixth anchor member;
(vi) positioning a length of the fifth locator member behind the fifth anchor member and the sixth anchor member such that a distal end of the fifth locator member extends between the sixth anchor member and the first anchor member;
(vii) positioning a length of the sixth locator member behind the sixth anchor member and the first anchor member such that a distal end of the sixth locator member extends between the first anchor member and the second anchor member;
(viii) verifying that the anchor members with caudal extensions are surrounded by the anchor members with cranial extensions; and
(ix) pulling the filter into a delivery sheath.

Abstract
A method of preparing a filter for delivery into a body vessel. The filter includes a hub disposed along a longitudinal axis and a plurality of anchor members extending from the hub. Each anchor member includes either a cranial extension or a caudal extension at a distal end thereof. At least one anchor member distal end may be spaced from the hub at each of a first, second, and third distance along the longitudinal axis. The filter also includes a plurality of locator members extending from the hub, the locator members alternatingly interposed between the anchor members.

12. A method of preparing a filter for delivery into a body vessel, the filter comprising N anchor members extending distally from a hub, the anchor members arranged and numbered successively counterclockwise about a circumference of the hub when viewed from a filter distal end, each anchor member including either a cranial extension or a caudal extension at a distal end thereof, and N locator members extending distally from the hub, the locator members arranged and numbered successively counterclockwise about a circumference of the hub when viewed from the filter distal end, each locator member extending from the hub between an adjacent pair of anchor members arranged such that locator member n is positioned immediately clockwise adjacent of anchor member n, wherein N is greater than 5, the method comprising:
-
(i) constraining the anchor members in a collapsed configuration; (ii) positioning a length of locator member 1 behind anchor member 1 and anchor member 2 such that a distal end of locator member 1 extends between anchor member 2 and anchor member 3; (iii) repeating step (ii) for locator members 2, 3, . . . , and N−
2(iv) positioning a length of locator member N−
1 behind anchor member N−
1 and anchor member N such that a distal end of locator member N−
1 extends between anchor member N and anchor member 1;(v) positioning a length of locator member N behind anchor member N and anchor member 1 such that a distal end of locator member N extends between anchor member 1 and anchor member 2; (vi) verifying that the anchor members with caudal extensions are surrounded by the anchor members with cranial extensions; and (vii) pulling the hub into a delivery sheath.
