Abstract

The invention comprises an embolisation device for insertably sealing a cannula. The embolisation device comprises a sealing cap at a first end and a carrier surface at a second end. The carrier surface is adapted to carry a coagulating material and induces an embolism at a position proximal to the second end and an elongate stem adapted to be inserted within the cannula.

Claims

1. An embolisation device for insertably sealing a cannula, wherein said embolisation device comprises a sealing cap at a first end, a carrier surface at a second end;

wherein the carrier surface is adapted to carry a coagulating material and induces an embolism at a position proximal to said second end and an elongate stem adapted to be inserted within the cannula.

2. The embolisation device of claim 1 wherein said embolisation device seals a cannula at a sealing point proximal to a heart of a patient, in use.

3. The embolisation device of claim 2 wherein said sealing cap is adapted to be sealingly connected to a corresponding connector of the cannula.

4. The embolisation device of claim 3 wherein the elongated stem is of a length so that when the device is entirely inserted within said cannula, the carrier surface is positioned to deliver coagulating material to a sealing point at some point proximal to a heart of a patient, in use.

5. The embolisation device of claim 3 wherein said sealing point is sufficiently close to the heart so that there is no requirement to remove the cannula from the body.

6. The embolisation device of claim 3 wherein said embolisation device is connected removably and releasably to the cannula, in use.
