Claims34
A haemostatic device suitable for use in a body cavity or vessel having an inner wall, comprising a haemostatic fabric and a mechanical means for outwardly expanding the fabric against the inner wall of the cavity or vessel.
A device according to any of preceding claims wherein the haemostatic fabric is a knitted, woven or braided fabric, or is non-woven.
A device according to any one of the preceding claims wherein the haemostatic fabric is a composite knitted, woven or braided fabric comprising a combination of:
- yarn which is gel-forming, said gel-forming yarn being woven, knitted or braided with a reinforcing yarn, the knitting, weaving or braiding of such reinforcing yarn comprising a network capable of providing physical integrity to said fabric independent of said gel-forming yarn or gel-forming yarn precursor.
A device according to any one of the preceding claims further comprising a friction-reducing layer which reduces the friction between the haemostatic fabric and the surface of the mechanical means during outwards expansion of the device.
A device according to any one of the preceding claims wherein the mechanical means is a sponge.
A device according to any one of the preceding claims which further comprises a deployment means.
A device as claimed in any preceding claim wherein the device comprises a fabric bag filled with filling material, wherein the filling material constitutes said mechanical means.
A device as claimed in any preceding claim wherein the device is provided with a release means for withdrawing the device from a cavity or vessel.
A device as claimed in any preceding claim wherein the device is provided with a biocidal agent.
A method for reducing bleeding in a body cavity or vessel comprising introducing a device as defined in any one of the preceding claims into the cavity or vessel and allowing the device to outwardly expand against the inner wall of the cavity or vessel.
A device substantially as described herein.
A device substantially as described herein with reference to one or more of the accompanying figures.
