Abstract

A surgical device for facilitating an intraluminal treatment of a stenosis in an anatomic vessel. The device comprises a spirally-configured constraint defining a spiral gap between convolutions that cooperates with a longitudinally-extending interior bore dimensioned to receive an anatomic vessel, for example an artery. The artery is disposed with the interior bore by "corkscrewing" the constraint around the exterior of the vessel, thus constraining the artery'"'"'s transverse dimension. In performing an exemplary method of the invention, the surgeon captures the artery in constraint'"'"'s interior bore and then widens the stenosis with a balloon catheter. The constraint allows the use of relatively high fluid pressures in the balloon catheter to compact occlusions in the stenosed vessel against the extraluminal constraint while at the same time limiting radial expansion of vessel walls to prevent over-expansion or perforation of the vessel.

Claims

1. A method of intraluminally treating an anatomic vessel, comprising the steps of:

introducing a helically shaped vessel-constraining structure into an interior of a body to a position proximate to an exterior of a vessel wall around a diseased portion of said anatomic vessel;

positioning said vessel-constraining structure substantially around said diseased portion thereby constraining a transverse dimension of said diseased portion;

advancing a working end of a transluminal catheter to said diseased portion; and

treating said diseased portion intraluminally with said working end of said transluminal catheter.

2. The method of claim 1, wherein said vessel-constraining structure comprises a spiral member defining a spiral gap and an interior bore, the positioning step including the steps of:

disposing said diseased portion in said spiral gap; and

helically and distally advancing said spiral member thereby positioning said diseased portion in said interior bore.

3. The method of claim 2, contemporaneous with the helically advancing step, the step of bluntly dissecting connective tissues in a plane around the exterior of the vessel wall with a blunt distal tip of the spiral member.

4. The method of claim 1, the positioning step including the step of contemporaneously viewing the positioning of the constraint with an imaging technology to insure the constraint is positioned in a particular location.

5. The method of claim 1, wherein the treating step includes treating said diseased portion with a dilation-type catheter.

6. The method of claim 5, wherein the treating step includes the step of compacting an occlusion within said diseased portion by pressing said occlusion between an expansion portion of said dilation catheter and said vessel-constraining structure.

7. The method of claim 1, wherein the treating step includes treating said diseased portion with an atherectomy-type catheter.

8. The method of claim 1, wherein the treating step includes treating said diseased portion with a placement of an intraluminal graft.

9. The method of claim 1, wherein the treating step includes treating said diseased portion with a placement of an intraluminal stent.
