Abstract
An amniotomy device includes a shaft having a rupture crown disposed along a distal end portion of the shaft. The rupture crown includes a distal end defined by at least two leading bite wings and a recess formed in the distal end of the rupture crown between the leading bite wings. The leading bite wings are configured to engage amniotic membrane when the shaft is rotated and rupture the amniotic membrane.
Claims19
An amniotomy device comprising:
- a shaft comprising a rupture crown disposed along a distal end portion of the shaft, the rupture crown comprising a distal end defined by at least two leading bite wings and a recess formed in the distal end of the rupture crown between the leading bite wings, wherein the rupture crown is structurally configured to be atraumatically inserted into a cervical canal;
- wherein the leading bite wings are structurally configured to atraumatically engage an amniotic membrane when the shaft is rotated.
An amniotomy device comprising:
- a shaft comprising a rupture crown disposed along a distal end portion of the shaft, the rupture crown comprising a distal end, a recess formed in the distal end, and a pair of bite wings curved in a circular arc along an exterior boundary of the rupture crown, wherein the rupture crown is structurally configured to be atraumatically inserted into a cervical canal;
- wherein the pair of bite wings are structurally configured to atraumatically grasp an amniotic membrane when the shaft is rotated.
An amniotomy device comprising:
- a shaft comprising a rupture crown disposed along a distal end portion of the shaft, the rupture crown comprising a distal face, a plurality of prongs extending axially relative to the shaft from the distal face, and a plurality of axial recesses formed in the distal face of the rupture crown, each of the plurality of prongs disposed between two adjacent axial recesses, wherein the rupture crown is structurally configured to be atraumatically inserted into a cervical canal;
- wherein the plurality of prongs are structurally configured to atraumatically grasp an amniotic membrane when the shaft is rotated.
