## Abstract

Uterine toner device (UTD) for reducing postpartum hemorrhage includes: a fundal portion including a first end and a second end of the fundal portion, the fundal portion including a conical shaped tip at the first end of the fundal portion; a cervical portion including a first end and a second end of the cervical portion, the first end of the cervical portion coupled to the second end of the fundal portion, where the fundal portion and the cervical portion each include a cylindrical and tubular shaped body, where the body of the cervical portion includes a first plurality of fenestrations; and at least one balloon coupled to a surface of the cervical portion, where when the balloon is inflated, the balloon seals the cervical portion without sealing the first plurality of fenestrations.

## Claims

### Claim 1

A uterine toner device, comprising:
a fundal portion comprising a first end and a second end of the fundal portion, the fundal portion comprising a conical shaped tip at the first end of the fundal portion;
a cervical portion comprising a first end and a second end of the cervical portion, the first end of the cervical portion coupled to the second end of the fundal portion, wherein the fundal portion and the cervical portion each comprise a cylindrical and tubular shaped body, wherein the body of the cervical portion comprises a first plurality of fenestrations; and
at least one balloon coupled to a surface of the cervical portion, wherein when the balloon is inflated, the balloon seals the cervical portion without sealing the first plurality of fenestrations.

### Claim 2 (depends on 1)

The device of claim 1, further comprising:
a tube coupled to the balloon, wherein liquid is injected into the balloon through the tube to inflate the balloon.

### Claim 3 (depends on 2)

The device of claim 2, wherein inflating the balloon causes release and separation of cervical tissues drawn into the plurality of fenestrations.

### Claim 4 (depends on 1)

The device of claim 1, further comprising:
a vaginal portion comprising a first end and a second end of the vaginal portion, the first end of the vaginal portion coupled to the second end of the cervical portion; and
a nipple portion comprising a first end and a second end of the nipple portion, the first end of the nipple portion coupled to the second end of the vaginal portion,
wherein the fundal portion, the cervical portion, the vaginal portion, and the nipple portion each comprise the cylindrical and tubular shaped body, wherein the body of the fundal portion comprises a second plurality of fenestrations,
wherein each of the second plurality of fenestrations has a diameter that is larger than the diameter of each of the first plurality of fenestrations.

### Claim 5

A method for reducing postpartum hemorrhage, comprising:
connecting an end of a suction tube of a pressure pump to a uterine toner device, the uterine toner device comprising:
a fundal portion comprising a first end and a second end of the fundal portion, the fundal portion comprising a conical shaped tip at the first end of the fundal portion;
a cervical portion comprising a first end and a second end of the cervical portion, the first end of the cervical portion coupled to the second end of the fundal portion, wherein the fundal portion and the cervical portion each comprise a cylindrical and tubular shaped body, wherein the body of the cervical portion comprises a plurality of fenestrations; and
at least one balloon coupled to a surface of the cervical portion;
inflating the balloon, wherein the inflated balloon seals the cervical portion without sealing the plurality of fenestrations, wherein the inflated balloon facilitates a release of cervical tissue drawn into the plurality of fenestrations; and
removing the uterine toner device.
