Three dimensional, low friction vasoocclusive coil, and method of manufacture
First Claim
1. A vasoocclusive device that is adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature for use in interventional therapy and vascular surgery, comprising:
- at least one strand of a flexible material formed to have a first portion with a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable, three dimensional substantially box shaped orthogonal configuration for occluding the desired part of the vasculature to be treated; and
a a second portion extending outwardly from the first portion in its second configuration and having a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable, substantially J-shape for filling and reinforcing the three dimensional shaped portion when the vasoocclusive device is implanted at the site in the vasculature to be treated.

Abstract
The three dimensional, low friction vasoocclusive coil has a portion that is three dimensionally box or cubed shaped. The three dimensional box or cubed shaped portion will form a basket for filling the anatomical cavity at the site in the vasculature to be treated. The vasoocclusive device is formed from at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter or cannula to a desired portion of the vasculature to be treated, and a second operable, three dimensional configuration for occluding the desired portion of the vasculature to be treated. The vasoocclusive coil may optionally include a portion that is substantially J-shaped or helically shaped, for filling and reinforcing the three dimensional portion.

13. A method of making a vasoocclusive device that is adapted to be inserted into a portion of a vasculature for occluding the portion of the vasculature for use in interventional therapy and vascular surgery, said vasoocclusive device being formed from at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and having a second operable, three dimensional configuration for occluding the desired portion of the vasculature to be treated, the method comprising the steps of:
-
winding at least one strand of a flexible material about an orthogonally shaped mandrel in a three dimensional configuration of the vasoocclusive device, said orthogonally shaped mandrel including a handle, and helically winding a portion of said at least one strand of flexible material about the handle;
heating said at least one strand of a flexible material for a sufficient period of time to impart the form to the material included in the device to form a first operable, three dimensional portion of the vasoocclusive device and a second operable, substantially J-shape portion of the vasoocclusive device extending outwardly from the three dimensional portion and configured filling and reinforcing the distal, three dimensional portion when the vasoocclusive device is implanted at the portion of the vasculature to be treated;
removing the vasoocclusive device from the mandrel; and
cold working the vasoocclusive device into a desired elongated configuration for placement into a catheter or cannula for use. - View Dependent Claims (14, 15, 16)

-
at least one strand of a flexible material formed to have a first portion with a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable, three dimensional substantially cube-shaped orthogonal configuration for occluding the desired part of the vasculature to be treated; and
a second portion extending outwardly from the first portion in its second configuration and having a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable, substantially J-shape for filling and reinforcing the distal, three dimensional shaped portion when the vasoocclusive device is implanted at the site in the vasculature to be treated.
