Abstract
The invention relates to a system for treating an epistaxis, comprising: a compressible body designed 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.
Core Innovation
The invention relates to a system for treating an epistaxis. The system includes a compressible member having a compressed configuration and an expanded configuration, configured to be introduced into a nasal cavity of a patient and passively expand to the expanded configuration to come into contact with walls of the nasal cavity. The compressible member comprises a shape-memory material such that it passively expands to the expanded configuration.
The system further includes an envelope configured to hermetically envelop the compressible member to form a sealed enclosure. A hollow compression device is provided for compressing the compressible member and the envelope to bring the compressible member into the compressed configuration, and in further embodiments the hollow compression device is configured to reduce a pressure in the compressible member and the envelope to bring the compressible member into the compressed configuration.
The system also includes a tube housed in a central recess of the compressible member extending between a proximal end and a distal end. The tube protrudes from the compressible member and comprises a fin configured to be attached to a zone of the body of a patient, and in related embodiments 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 attaches the compression device in proximity to the proximal end of the compressible member.
Claims Coverage
The independent claims cover a core system architecture with a compressible shape-memory nasal member, a hermetically enclosing envelope, and a hollow compression device, and separate independent claim sets for tube, fin, and lock structures. Across the independent claims, four inventive features are specified: passive expansion of a shape-memory compressible member, hermetic sealing by an envelope, hollow compression to bring the member into a compressed configuration, and tube structures associated with body attachment and attachment of the compression device.
Shape-memory compressible nasal member with passive expansion
A compressible member having a compressed configuration and an expanded configuration, configured to be introduced into a nasal cavity of a patient and to come into contact with walls of the nasal cavity in the expanded configuration, wherein the compressible member comprises a shape-memory material such that the compressible member passively expands to the expanded configuration.
Hermetic envelope forming a sealed enclosure
An envelope configured to hermetically envelop the compressible member so as to form a sealed enclosure.
Hollow compression device for compressed configuration
A hollow compression device for compressing the compressible member and the envelope to bring the compressible member into the compressed configuration; and in further embodiments, 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.
Central recess tube with proximal-end lock attachment
A tube housed in a central recess of the compressible member extending between the proximal end and the distal end, 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.
Central recess tube with protruding fin body attachment
A tube housed in a central recess of the compressible member extending between the proximal end and the distal end, 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.
The claim coverage centers on a sealed-enclosure nasal epistaxis treatment system using a shape-memory compressible member that passively expands to contact nasal cavity walls, combined with a hermetically enveloping envelope and a hollow compression device that establishes a compressed configuration. Additional independent coverage specifies tube structures housed in a central recess, including a proximal-end lock for attaching the compression device and a protruding fin for attaching to a zone of the body.
