Abstract
Abstract A vein suture collar (10) for anchoring an electrode lead to a vein in which the lead is inserted includes a sleeve member (12) having three longitudinally spaced circumferential suture grooves (26,28,30) in the exterior surface (18) and a raised web area (32,34,36) formed on the interior sleeve surface (24) radially inward of each groove (26,28,30). The three raised web areas (32,34,36) are angularly spaced about the sleeve axis (16) and a longitudinal slit through the sleeve thickness can be provided. The slit collar can be separated at the slit and used to enclose the portion of the vein having the inserted electrode.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
53 words
A vein suture collar comprising: a cylindrical member having a through-bore along the longitudinal axis thereof; a plurality of circumferential grooves formed in the exterior surface of said member and spaced longitudinally; and a plurality of raised web areas formed on the interior surface of said member and extending radially into said through-bore.
Claim 2
Dependent Claim
53 words
A vein suture collar comprising: a cylindrical member having a through-bore along the longitudinal axis thereof; a plurality of circumferential grooves formed in the exterior surface of said member and spaced longitudinally; and a plurality of raised web areas formed on the interior surface of said member and extending radially into said through-bore.
Claim 3
Dependent Claim
26 words
The collar as in claim 1 wherein each of said plurality of raised web areas is located to radially oppose a respective one of said grooves.
Claim 4
Dependent Claim
21 words
The collar as in claim 1 wherein said raised web areas are angularly spaced about the interior surface of said member.
Claim 5
Dependent Claim
11 words
The collar as in claim 1 having three longitudinally spaced grooves.
Claim 6
Dependent Claim
34 words
The collar as in claim 1 having three raised web areas spaced along the longitudinal axis of said member and angularly spaced about the interior surface of said member at about 60 degree intervals.
Claim 7
Dependent Claim
18 words
The collar as in claim 1 wherein each of said raised web areas is generally circular in shape.
Claim 8
Dependent Claim
99 words
A vein suture collar for enclosing and protecting a vein and an electrode lead inserted in the vein, the collar comprising: a cylindrical sleeve formed of a resilient material; a plurality of circumferential suture grooves formed in the exterior sleeve surface and spaced longitudinally; a plurality of raised web areas formed on the interior surface of said sleeve and extending inwards and radially; and a slit extending longitudinally along the entire length of said sleeve and radially through the thickness of said sleeve, said sleeve being resiliently spreadable at said slit to enclose the vein and inserted electrode lead.
Claim 9
Dependent Claim
99 words
A vein suture collar for enclosing and protecting a vein and an electrode lead inserted in the vein, the collar comprising: a cylindrical sleeve formed of a resilient material; a plurality of circumferential suture grooves formed in the exterior sleeve surface and spaced longitudinally; a plurality of raised web areas formed on the interior surface of said sleeve and extending inwards and radially; and a slit extending longitudinally along the entire length of said sleeve and radially through the thickness of said sleeve, said sleeve being resiliently spreadable at said slit to enclose the vein and inserted electrode lead.
Claim 10
Dependent Claim
28 words
The collar as in claim 7 having three circumferential grooves and three raised web areas, said web areas being angularly spaced about the interior surface of said sleeve.
Claim 11
Dependent Claim
24 words
The collar as in claim 7 wherein each of said raised web areas is formed to radially oppose a respective one of said grooves.
Claim 12
Dependent Claim
102 words
In a vein suture collar of the type for anchoring an electrode inserted in a vein to be ligated, the collar having a cylindrical sleeve body with a suture groove circumferentially disposed in the exterior sleeve surface for use in securing the collar, the improvement comprising: at least one additional circumferential suture groove spaced longitudinally from the first groove; the collar having an inside diameter greater than the outside diameter of the vein with the inserted electrode; and means located on the interior surface of the sleeve for providing an interference fit with the electrode at discrete longitudinal positions along the sleeve.
Claim 13
Dependent Claim
102 words
In a vein suture collar of the type for anchoring an electrode inserted in a vein to be ligated, the collar having a cylindrical sleeve body with a suture groove circumferentially disposed in the exterior sleeve surface for use in securing the collar, the improvement comprising: at least one additional circumferential suture groove spaced longitudinally from the first groove; the collar having an inside diameter greater than the outside diameter of the vein with the inserted electrode; and means located on the interior surface of the sleeve for providing an interference fit with the electrode at discrete longitudinal positions along the sleeve.
Claim 14
Dependent Claim
32 words
The improved collar as in claim 10 further including a longitudinal slit in the sleeve, the sleeve being resiliently separable at said slit for enclosing the vein portion having the inserted electrode.
Claim 15
Dependent Claim
31 words
The improved collar as in claim 10 wherein said means for providing an interference fit includes a plurality of angularly spaced raised web areas extending radially inward of the interior surface.
Claim 16
Dependent Claim
120 words
Method of installing a suture collar for use in tieing a vein to an inserted electrode lead, the collar comprising a cylindrical sleeve of a flexible material with a plurality of circumferential grooves in the exterior sleeve surface spaced in the longitudinal sleeve direction, the method comprising the steps of: a) forming a slit in the sleeve in the longitudinal direction and through the sleeve wall thickness; b) separating the sleeve at the slit; c) enveloping the portion of the vein having the inserted electrode lead with the separated sleeve; and d) closing the sleeve at the slit, said closing step including the step of applying sutures to each of the plurality of grooves to abut the slit sleeve edges.
Claim 17
Dependent Claim
120 words
Method of installing a suture collar for use in tieing a vein to an inserted electrode lead, the collar comprising a cylindrical sleeve of a flexible material with a plurality of circumferential grooves in the exterior sleeve surface spaced in the longitudinal sleeve direction, the method comprising the steps of: a) forming a slit in the sleeve in the longitudinal direction and through the sleeve wall thickness; b) separating the sleeve at the slit; c) enveloping the portion of the vein having the inserted electrode lead with the separated sleeve; and d) closing the sleeve at the slit, said closing step including the step of applying sutures to each of the plurality of grooves to abut the slit sleeve edges.
