Abstract
A disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity is elongate along a reference axis, has an intrinsic axial consistency which is sufficient to allow the device to be introduced into the cavity by being pushed in axially. The device includes an expandable tampon made of at least one absorbent material, having a proximal portion and a distal portion, designed to collect and absorb said active liquid dispensed in the intracorporeal cavity and to expand and bear in a leak tight manner against mucous membrane of the intracorporeal cavity, and a source of liquid phase including a capsule, at least the proximal part of which is at least partially surrounded by the expandable tampon.

A disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, said device comprising:
- an expandable tampon made of at least one absorbent material, having a proximal portion and a distal portion, designed to collect and absorb said active liquid dispensed in the intracorporeal cavity and to expand and bear in a leak tight manner against mucous membrane of the intracorporeal cavity;
- a source of liquid phase comprising a capsule at least the proximal part of which is at least partially surrounded by said expandable tampon;
- a covering for temporary protection at least partially covering the distal portion of said capsule, and extending longitudinally to an intermediate level of the tampon in such a way as to form in said tampon a proximal plug not covered by said covering, which is at least radially expandable independently from the remaining part of said tampon.
A disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, said device comprising:
- an expandable tampon made of at least one absorbent material, having a proximal portion and a distal portion, designed to collect and absorb said active liquid dispensed in the intracorporeal cavity and to expand and bear in a leak tight manner against mucous membrane of the intracorporeal cavity, at least one part of said distal portion of said tampon being axially expandable upon absorption of liquid;
- and
- a source of liquid phase comprising a capsule at least the proximal part of which is at least partially surrounded by said expandable tampon.
A disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, said device comprising:
- an expandable tampon made of at least one absorbent material, having a proximal portion and a distal portion, designed to collect and absorb said active liquid dispensed in the intracorporeal cavity and to expand and bear in a leak tight manner against mucous membrane of the intracorporeal cavity;
- a source of liquid phase comprising a capsule at least the proximal part of which is at least partially surrounded by said expandable tampon;
- and
- a withdrawal string attached to said capsule or said tampon, said withdrawal string entering and exiting said tampon at spaced apart locations in a proximal end face of said tampon.
A disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, said device comprising:
- an expandable tampon made of at least one absorbent material, having a proximal portion and a distal portion, designed to collect and absorb said active liquid dispensed in the intracorporeal cavity and to expand and bear in a leak tight manner against mucous membrane of the intracorporeal cavity;
- a source of liquid phase comprising a capsule at least the proximal part of which is at least partially surrounded by said expandable tampon;
- and
- an absorption barrier that acts in a predetermined and differentiated manner, resulting in at least one non absorbing zone of said tampon showing a reduced absorption capacity of the active liquid, and in at least one absorbing zone of said tampon maintaining the absorption capacity of the active liquid.
A method of making a disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, comprising:
- radially compressing at least a first portion of an expandable tampon;
- axially compressing at least a second portion of said expandable tampon;
- and
- providing said expandable tampon with a source of liquid phase.
Apparatus for making a disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, comprising:
- means for radially compressing at least a first portion of an expandable tampon;
- means for axially compressing at least a second portion of said expandable tampon;
- and
- means for providing said expandable tampon with a source of liquid phase.
Apparatus for making a disposable device for transferring and/or circulating an active liquid into and/or inside an intracorporeal cavity, said device being elongate along a reference axis, said device having an intrinsic axial consistency which is sufficient to allow said device to be introduced into said cavity by being pushed in axially, comprising:
- a die configured to radially compress at least a first portion of an expandable tampon;
- a die configured to axially compress at least a second portion of said expandable tampon;
- and
- a loader configured to provide said expandable tampon with a source of liquid.
