Abstract
A suturing device is provided. The suturing device may include a firing aperture having at least one needle and a stripper plate, the needle being rotatable relative to the stripper plate and the firing aperture, and configured to engage a suture for deployment; and a drive mechanism operatively coupled to the needle and configured to advance the needle from a retracted position to an extended position during engagement, and retract the needle from the extended position to the retracted position during disengagement.
Claims22
A suturing device, comprising:
- a firing aperture having a first needle, a second needle and a stripper plate, the first and second needles being rotatable relative to the stripper plate and the firing aperture, and configured to engage a suture for deployment;
- and
- a drive mechanism operatively coupled to the first and second needles and configured to advance the first and second needles from a retracted position to an extended position in substantially equal increments but in opposing directions during a first operation of the drive mechanism, and retract the first and second needles from the extended position to the retracted position in substantially equal increments but in opposing directions during a second operation of the drive mechanism.
A suturing device, comprising:
- a firing aperture having a first needle and a second needle configured to be rotatable relative to the firing aperture and engage a suture for deployment;
- a stripper plate coupled to the firing aperture, the stripper plate having at least a guard member and one or more extension elements extending therefrom;
- and
- a drive mechanism operatively coupled to the first and second needles and configured to advance the first and second needles from a retracted position to an extended position in substantially equal increments but in opposing directions during a first operation of the drive mechanism, and retract the first and second needles from the extended position to the retracted position in substantially equal increments but in opposing directions during a second operation of the drive mechanism.
A suturing device, comprising:
- an elongate member extending between a working end and a control end and configured to receive one or more deployable sutures, the working end having a firing aperture, a distal needle, a proximal needle, and a stripper plate coupled to the firing aperture;
- and
- a drive mechanism disposed within the elongate member and operatively coupling the control end with each of the distal and proximal needles, the drive mechanism being configured to advance the distal and proximal needles from retracted positions to extended positions in substantially equal increments but in opposing directions during a first operation of the drive mechanism, and retract the distal and proximal needles from the extended positions to the retracted positions in substantially equal increments but in opposing directions during a second operation of the drive mechanism.
