Abstract
Methods and devices are provided for closing a puncture wound. In one exemplary embodiment, a puncture closure device is provided having an elongate tubular body that is disposable through a puncture in tissue and that includes proximal and distal portions. The proximal portion can be adapted to expand to form proximal wings upon rotation of the elongate tubular body, preferably in a first direction. The distal portion can be adapted to expand to form distal wings upon rotation of the elongate tubular body, preferably in a second, opposite direction. The proximal and distal portions can also be adapted to be moved toward one another as they expand upon rotation. As a result, the proximal and distal wings can engage tissue therebetween.
Claims42
A puncture closure device, comprising:
- an elongate tubular body disposable through a puncture in tissue and having proximal and distal portions, the proximal portion being adapted to expand to form proximal wings upon rotation of the elongate tubular body in a first direction, and the distal portion being adapted 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.
A system for closing a puncture in tissue, comprising:
- an elongate tubular body having proximal and distal portions with a plurality of slits formed therein, the elongate tubular body being adapted to extend outwardly between each of the plurality of slits formed in the proximal and distal portions such that the proximal and distal portions are adapted to engage tissue therebetween;
- and
- an actuator removably coupled to the elongate tubular body and adapted to apply an axial and rotational force to the elongate tubular body to cause the elongate tubular body to extend outwardly.
A method for closing a puncture in tissue, comprising:
- inserting an elongate tubular body through a puncture in tissue;
- and
- rotating proximal and distal portions of the elongate tubular body to expand the proximal and distal portions such that tissue surrounding the puncture is engaged between the expanded proximal and distal portions thereby sealing the puncture.
