to come into contact with walls of a nasal cavity of a patient, or surrounded by a veil of hemostatic properties; an envelope designed to envelop the compressible body; and a compression device for compressing the compressible body in the envelope, said compression device being designed so as to compress or release the compressible body. ## Claims ### Claim 1 A system for treating an epistaxis, comprising: a compressible member having a compressed configuration, in which the compressible member is compressed and is configured to be introduced into a nasal cavity of a patient, and an expanded configuration, in which the compressible member is deployed and is configured to come into contact with walls of the nasal cavity of the patient, wherein the compressible member comprises a shape-memory material such that the compressible member passively expands to the expanded configuration; and an envelope configured to hermetically envelop the compressible member so as to form a sealed enclosure, a hollow compression device for compressing the compressible member and the envelope to bring the compressible member into the compressed configuration. ### Claim 2 (depends on 1) The system according to claim 1, wherein the envelope comprises a flexible film. ### Claim 3 (depends on 2) The system according to claim 2, wherein the envelope comprises a film having a thickness of up to one hundred microns and is made of at least one of the following materials: polyethylene, polyurethane. ### Claim 4 (depends on 1) The system according to claim 1, wherein the compression device comprises a syringe or a partial vacuum member. ### Claim 5 (depends on 1) The system according to claim 1, wherein the compressible member has a proximal end and a distal end, a central recess being formed between the proximal end and the distal end of the compressible member and the system further comprising a tube housed in the central recess. ### Claim 6 (depends on 5) The system according to claim 5, wherein the tube comprises through openings between the proximal end and the distal end of the compressible member and is configured to put the compressible member and the envelope into fluid communication with the compression device to allow progressive compression and expansion of the compressible member over an entire length of the compressible member. ### Claim 7 (depends on 5) The system according to claim 5, further comprising a lock comprising a first attachment member, attached to a proximal end of the tube and a second complementary attachment member attached to the compression device. ### Claim 8 (depends on 5) The system according claim 5, wherein the tube protrudes from the compressible member and comprises a fin configured to be attached to a zone of the body of a patient. ### Claim 9 (depends on 1) The system according to claim 1, wherein the envelope has is planar sheet or a sleeve. ### Claim 10 (depends on 1) The system according to claim 1, further comprising a veil having hemostatic properties covering the envelope. ### Claim 11 (depends on 1) the system according to claim 1, wherein the shape-memory material comprises a foam. ### Claim 12 (depends on 1) The system of claim 1, wherein the compression device is configured to reduce a pressure in the compressible member and the envelope. ### Claim 13 (depends on 12) The system of claim 12, wherein the compression device includes a syringe. ### Claim 14 A system for treating an epistaxis, comprising: a compressible member having a proximal end and a distal end, wherein the compressible member has a compressed configuration, in which the compressible member is compressed and is configured to be introduced into a nasal cavity of a patient, and an expanded configuration, in which the compressible member is deployed and is configured to come into contact with walls of the nasal cavity of the patient, an envelope configured to hermetically envelop the compressible member so as to form a sealed enclosure, a hollow compression device configured to reduce a pressure in the compressible member and the envelope and bring the compressible member into the compressed configuration, a tube housed in a central recess of the compressible member that extends between the proximal end and the distal end of the compressible member, and a lock comprising a first attachment member, attached to a proximal end of the tube and a second complementary attachment member attached to the compression device such that the compression device is attached in proximity to the proximal end of the compressible member. ### Claim 15 (depends on 14) The system of claim 14, wherein the compressible member comprises a shape- memory material. ### Claim 16 (depends on 15) The system of claim 15, wherein the shape-memory material of the compressible member is arranged such that the compressible member passively expands to the expanded configuration. ### Claim 17 (depends on 14) The system of claim 14, wherein the envelope comprises a film. ### Claim 18 A system for treating an epistaxis, comprising: a compressible member having a proximal end and a distal end, wherein the compressible member has a compressed configuration, in which the compressible member is compressed and is configured to be introduced into a nasal cavity of a patient, and an expanded configuration, in which the compressible member is deployed and is configured to come into contact with walls of the nasal cavity of the patient, an envelope configured to hermetically envelop the compressible member so as to form a sealed enclosure, a hollow compression device configured to reduce a pressure in the compressible member and the envelope and bring the compressible member into the compressed configuration, a tube housed in a central recess of the compressible member that extends between the proximal end and the distal end of the compressible member, wherein the tube protrudes from the compressible member and comprises a fin configured to be attached to a zone of the body of a patient.
