Abstract

A hemostatic device comprising, a catheter having an elongated elastic shaft, an inflatable balloon adjacent a distal end of the shaft, and a sidearm adjacent a proximal end of the catheter. The device has a traction member comprising a retaining portion to receive the catheter shaft and sidearm, with the retaining portion being connected to an object to maintain the catheter shaft under selected tension.

Claims

1. A hemostatic device, comprising:

a catheter having an elongated shaft of elastic material, an inflatable balloon adjacent a distal end of the shaft, and a sidearm adjacent a proximal end of the catheter extending outwardly from the shaft;

a traction member comprising, a retaining portion having a bore in which the catheter shaft is removably positioned, a side channel in which the catheter side arm is removably positioned communicating with said bore and extending at an angle from the bore toward a proximal end of the retaining portion, said retaining portion having a slot extending between the channel and bore to permit passage of the catheter sidearm into the side channel during placement of the catheter in the traction member with the juncture of the catheter shaft and sidearm being located adjacent the juncture of the retaining portion bore and side channel, said traction member having means for connecting the retaining portion to an object to maintain the catheter shaft under selected tension.

2. The device of claim 1 wherein the inner dimensions of said bore and side channel are approximately equal to the respective outer dimensions of the catheter shaft and sidearm.

3. The device of claim 1 wherein the inner dimensions of said slot are slightly less than the outer dimensions of the catheter sidearm.

4. The device of claim 1 wherein the connecting means comprises a pair of elongated wings extending outwardly from opposed sides of the retaining portion.

5. The device of claim 4 wherein said wings are relatively flat and define a plane generally aligned with a plane defined by the axes of said bore and side channel.

6. The device of claim 4 wherein said wings define an elongated generally planar attachment surface.

7. The device of claim 6 wherein said retaining portion defines a continuation of said attachment surface.

8. The device of claim 6 wherein said wings include an adhesive on said attachment surface, and release sheet means releasably attached to said adhesive.

9. The device of claim 4 wherein said wings include an elongated slot to permit passage of attachment members through said slots.

10. The device of claim 1 wherein said traction member includes an indicating element extending distally from said retaining portion to define a reference position relative the shaft.

11. The device of claim 10 wherein said indicating element extends at least partially circumferentially around the catheter shaft when the catheter is received in the traction member.

12. The device of claim 11 wherein said indicating element comprises a generally tubular section having an elongated opening sufficiently large to permit removal of the catheter shaft from the tubular section through said opening.

13. The device of claim 10 wherein said indicating element has a distal edge defining a reference position, and in which the catheter shaft has a plurality of spaced indicia alignable with the reference edge responsive to variable tension in the catheter shaft.

14. The device of claim 1 wherein said catheter has means for indicating the amount of tension in the catheter shaft.

15. The device of claim 1 wherein said catheter includes a second sidearm adjacent a proximal end of the shaft and extending outwardly from the shaft on a side opposed to the first sidearm, in which said retaining portion includes a second side channel communicating with said bore and extending at an angle from the bore on an opposed side of the bore relative the first side channel, and in which the retaining portion includes a slot extending between said bore and second side channel to permit passage of the second side arm into the second side channel during placement of the catheter in the traction member.
