Abstract

The suture collar (20) is used with a pacing lead body (12), and comprises a generally cylindrical body having a throughbore (46) therethrough for receiving therethrough the pacing lead body 12, the cylindrical body (20) including a middle barrel portion (29) and tapering end portions (30 and 32), each of which taper from the barrel portion (28) to a sleeve end section (70 and 72). The barrel portion (28) is separated from the tapering end portions (30 and 32) by first and second suture receiving annular grooves (34 and 36), and the barrel portion has four slits (41-44) therein to facilitate squeezing of the barrel portion 28 around lead body (12) when sutures (24 and 26) are tied in the grooves.

The suture collar (20) of the type defined above is secured to a lead body (12) by the following method including the steps of: sliding the suture collar (20) on the lead body (12) to the place of entry of the lead body (12) into a vein after an electrode tip has been inserted into and properly located within a ventricle or atrium of a heart (14); tying sutures (24 and 26) to the underlying tissue or the ligated vein in the area of the annular grooves (34 and 36); and then securing the sutures (24 and 26) tightly around the collar (20) in each groove (34 or 36) so as to cause radial displacement of the barrel portion quarter sections (81-84) against the lead body (12).

Claims

1. A suture collar for use with a pacing lead body, said collar comprising a generally cylindrical body having opposite ends and having a throughbore therethrough for receiving a pacing lead body, said cylindrical body including a middle barrel portion and tapering end portions, each of which taper from the barrel portion to one of said ends, said barrel portion being separated from said tapering end portions by first and second suture receiving annular grooves, and said barrel portion having at least two generally longitudinally extending slits therein, each extending generally radially inwardly from the outer surface of said barrel portion to said throughbore to facilitate squeezing of the cylindrical body around a lead body when a suture is tied in one of said grooves.

2. The suture collar of claim 1 wherein each one of said slits extends axially into the area between the bottom of each groove and said throughbore.

3. The suture collar of claim 1 wherein said barrel portion has four slits therein.

4. The suture collar of claim 3 wherein each of said slits extends axially into the area between the bottom of each of said grooves and said throughbore.

5. The suture collar of claim 4 wherein said slits ae approximately 90°

apart around the barrel portion to form barrel portion quarter sections.

6. The suture collar of claim 1 being made of an elastomeric plastic material.

7. The suture collar of claim 6 wherein said suture collar is made of a silicone elastomer.

9. The suture collar of claim 1 wherein said slits are generally diametrically opposite each other.

10. The suture collar of claim 1 including three slits.

8. A method of securing a suture collar comprising a generally cylindrical body having opposite ends and having a throughbore therethrough for receiving a pacing lead body, said cylindrical body including a middle barrel portion and tapering end portions, each of which taper from the barrel portion to one of said ends, said barrel portion being separated from said tapering end portions by first and second suture receiving annular grooves, and said barrel portion having at least two generally longitudinally extending slits therein, each extending generally radially inwardly from the outer surface of said barrel portion to said throughbore to facilitate squeezing of the barrel portion around a lead body when a suture is tied in one of said grooves, said method including the steps of:

sliding the suture collar on a lead body to the place of entry of the lead body into a vein after an electrode tip has been inserted into and properly located within a ventricle or atrium of a heart;

tying sutures to the underlying tissue or the ligated vein in the area of the annular grooves; and

then securing the sutures tightly around the collar in each groove so as to cause the cylindrical body to grip the lead body.
