1. A device for creating a seal around an incision in a blood vessel which allows blood to flow through the blood vessel, comprising:

  • a tube;

    a shaft slidably mounted within said tube;

    a retaining member which prevents relative movement between said shaft and said tube, said retaining member being releasable to allow said relative movement;

    a deformable sealing member adjoining distal ends of said shaft and said tube, said sealing member being reversibly adjustable, between;

    an elongated, narrow configuration for insertion of said sealing member through the incision; and

    a sealing configuration in which (i) a first portion of said sealing member seals against an inner wall of the blood vessel, and (ii) a second portion of said sealing member, interior to said first portion, is spaced from the inner wall of the blood vessel to form a cavity which provides a region of hemostasis within the blood vessel;

    wherein the configuration of said sealing member is changed by movement of said shaft relative to said tube.
