Abstract:
1. A puncture closure device, comprising: an elongate tubular body disposable through a puncture in tissue and having proximal and distal portions, the proximal portion having a plurality of proximal slits formed therein extending in a first direction around a circumference of the elongate tubular body, the proximal slits being configured to allow portions of the elongate tubular body surrounding the plurality of proximal slits to expand to form proximal wings upon rotation of the elongate tubular body in a first direction, and the distal portion having a plurality of distal slits formed therein extending in a second opposite direction around the circumference of the elongate tubular body, the distal slits being configured to allow portions of the elongate tubular body surrounding the plurality of distal slits to expand to form distal wings upon rotation of the elongate tubular body in a second direction opposite to the first direction, whereby the proximal and distal wings are adapted to engage tissue therebetween, the proximal and distal slits having terminal ends with additional slits extending therefrom in opposite directions.
