Fecal impaction removal device
A fecal impaction removal device includes an elongated shaft extending along a central longitudinal axis. A dilation body is secured at a distal end of the elongated shaft for insertion into a rectum of a patient. The dilation body has a maximum radial extension in a direction orthogonal to the central longitudinal axis. The fecal impaction removal device includes a stop member that extends from a central region of the elongated shaft. The stop member has a length along a major axis that is greater than the maximum radial extension of the dilation body.
