Abstract
A fetus delivery assisting device (10) for assisting with the birth of a fetus. The device (10) comprises a shaft (16). At one end of the shaft (16) is a rigid base (18) to which an inflatable balloon (12) is mounted. The rigid base (18) and the inflatable balloon (12) are configured to accept a fetal head. The inflatable balloon (12) is configured to displace the fetal head from a pelvic cavity when inflated. The shaft (16) is configured for manipulating the inflatable balloon (12) to displace the fetal head from the pelvic cavity.
Claims20
A fetus delivery assisting device comprising:
- a base;
- a rigid shaft comprising a first end coupled to the base and a second end having a fixed arcuate shape;
- and
- an inflatable balloon mounted to the base along a first side of the base,
- wherein the base and the inflatable balloon are configured to be positioned with the inflatable balloon in a deflated state between a fetal head of a fetus and a wall of a pelvic cavity,
- wherein the inflatable balloon is configured to contact the fetal head to displace the fetal head away from the wall of the pelvic cavity when the inflatable balloon is between the fetal head and the wall of the pelvic cavity and is inflated,
- wherein the base comprises surface features along a second side of the base that is opposite to the first side of the base such that the surface features are spaced apart from the fetus when the inflatable balloon is in contact with the fetal head,
- wherein the surface features are configured to provide friction between the base and the wall of the pelvic cavity,
- wherein each of the surface features extends from a flat portion of the base, and
- wherein the inflatable balloon is capable of receiving a fluid volume of 500 cubic centimeters.
A method of repositioning a fetal head of a fetus in a pelvic cavity, the method comprising:
- positioning a device between the fetal head and a wall of the pelvic cavity, wherein the device comprises a rigid shaft having a first end coupled to a base and a second end having a fixed arcuate shape, and an expandable member attached to the base along a first side of the base, wherein the device comprises surface features along a second side of the base that faces the wall of the pelvic cavity, the second side of the base being opposite to the first side of the base such that the surface features are spaced apart from the fetus and are in frictional engagement with the wall of the pelvic cavity, and wherein each of the surface features extends from a flat portion of the base;
- and
- expanding the expandable member in a normal direction from the base to cause the expandable member to contact the fetal head to move the fetal head away from the wall of the pelvic cavity, wherein the expandable member is capable of receiving a fluid volume of 500 cubic centimeters.
