Abstract
An intra-uterine device for treating post-partum hemorrhage (PPH) is described, along with an applicator system. In embodiments, the PPH device is comprised of a mesh pouch that is filled with a plurality of sponges. Each sponge is designed to expand upon absorption of fluids, such as blood. The collective expansion of the sponges within the mesh pouch causes the PPH device to expand within a patient's uterus, thus applying pressure to stanch blood flow. The PPH device is loaded into an applicator which is then inserted into a patient, and a corresponding plunger is used to deploy the PPH device. Following completion of treatment, the PPH device may be removed using a removal strand attached to the pouch that is exposed outside of the patient.
Claims23
A method for treating post-partum hemorrhaging (PPH), comprising placing a plurality of sponges disposed within a tubular pouch, into a patient's uterus, wherein:
- each of the plurality of sponges is configured to expand in volume upon absorption of a fluid;
- the tubular pouch is comprised of a mesh material;
- the tubular pouch has a length and a cross section, and is elongated in its length relative to its cross section;
- the plurality of sponges is configured to expand within the patient's uterus by absorbing blood;
- and
- a sponge tip enclosed within a compartment of the tubular pouch separate from the plurality of sponges or disposed on an outside of the tubular pouch.
A device for treating post-partum hemorrhaging (PPH), comprising:
- a tubular pouch having a first end and a second end distal from the first end, the tubular pouch comprised of a mesh material, the tubular pouch having a length and a cross section, wherein its length is elongated relative to its cross section;
- a plurality of sponges disposed within the tubular pouch, each of the plurality of sponges configured to expand in volume upon absorption of a fluid;
- and
- a sponge tip enclosed within a compartment of the tubular pouch separate from the plurality of sponges or disposed on an outside of the tubular pouch;
- wherein the tubular pouch is configured to expand as at least a subset of the plurality of sponges expands upon absorption of the fluid.
A system for treating post-partum hemorrhaging (PPH), comprising:
- a PPH device comprised of:
- a porous tubular pouch that has a length and a cross section, and is elongated in its length relative to its cross section;
- a plurality of sponges disposed within the tubular pouch, each sponge comprised of a material that expands in volume upon absorption of a fluid;
- and
- a sponge tip enclosed within a compartment of the tubular pouch separate from the plurality of sponges or disposed on an outside of the tubular pouch;
- an applicator comprised of a hollow tube, sized to receive and enclose the PPH device;
- and
- a plunger configured to insert into the hollow tube.
