As is recognized in U.S. Pat. No. 6,368,341, which is granted to Abrahamson, a drawback with the types of sealing devices described in the above-mentioned U.S. Pat. Nos. 4,744,364, 4,852,568 and 4,890,612 is that an intra-arterial sealing device extending into a blood vessel may obstruct the flow of blood therethrough. The sealing device according to U.S. Pat No. 6,368,341 comprises a haemostatic closure device and a locating device having one or several locating members to be positioned against the inner surface of the vessel wall. The locating members are designed to provide a sufficient amount of resistance against retracting movement, so that a user is provided with an indication that the locating members are in contact with the inner vessel wall. When correctly positioned, the haemostatic closure device, which may include a clotting agent, is in the incision channel outside the vessel wall and there are no portions extending into the vessel, where such portions may obstruct the flow of blood.
FIG. 8 shows the cross-section of the closure device 9, which is connected to an introducer 15 by means of the attachment member 14. The figure illustrates how the stationary part 12 and the retractable part 13 together provide the space in which the haemostatic material 10 is contained. FIG. 8 also shows spacers/guides S between retractable part 13 and haemostatic material 10. It can also be seen that the retractable part 13 is in slidable engagement with the stationary part 12 by means of projections 13a and 13b from the retractable part 13 that engage in grooves in the stationary part 12. Such projections and grooves may have a variety of different shapes. The attachment member 14 is attached to the distal portion of the stationary part 12, and a comparison of FIG. 8 with FIG. 3 reveals the difference between the attachment member 14 and the attachment member 6 of FIG. 3. Whereas the attachment member 6 is attached to the retractable part 5 of the closure device 1, the attachment member 14 is attached to the stationary part 12 of the closure device 9. This means that, during the retracting movement, the attachment member 14 remains in position on the introducer 15, which may facilitate a smooth operation of a closure device according to the present invention. Here it should be noted that instead of providing a single attachment member, a number of attachment members, e.g. in the form of flexible rings each provided with a slit, could be arranged spaced apart along the length of an insertion assembly.
FIG. 11 shows the cross-section of the closure device 16 connected to an introducer 22a. In particular, the slit 23 is visible. By means of this slit 23 and by manufacturing the retractable part 20 from a flexible material (such as plastic), the retractable part 20 can be snapped onto an introducer, such as introducer 22a. Consequently, the slit 23 constitutes the attachment means for this embodiment of a closure device and replaces fastening means attached to the exterior of an insertion assembly. In this third embodiment, the slit 23 is only a narrow gap between the longitudinal edges of the hollow sheath that basically constitutes the retractable part 20. Further, the inner wall 21 and the outer wall 22 extend essentially all the way from the first longitudinal edge to the opposing second longitudinal edge, i.e. as much space as possible has been obtained for the haemostatic material 18.
