Abstract

A suturing device includes an elongate shaft defining a longitudinal axis, a trajectory guide translatably mounted on the elongate shaft and an introducer guard member operatively coupled to a distal portion of the elongate shaft. The introducer guard member includes at least one arm member which is movable between a first position in which the arm member is retracted, substantially in alignment with the longitudinal axis and a second position in which the at least one arm member is deployed. The introducer guard member includes an attaching member for releasably retaining a suture. The trajectory guide defines at least one bore therethrough. The bore obliquely extends through the trajectory guide and defines an angle with respect to the longitudinal axis. The bore aligns with the attaching member when the introducer guard member is in the second position.

Claims

1. A suturing device comprising:

an elongate shaft defining a longitudinal axis;

a trajectory guide movable along the elongate shaft; and

an introducer guard member operatively coupled to the elongate shaft, the introducer guard member including at least one arm member movable between a first position in which the at least one arm member is in alignment with the longitudinal axis and a second position in which the at least one arm member defines an acute angle with respect to the longitudinal axis, wherein the trajectory guide is translatable independently of the introducer guard member.

2. The suturing device according to claim 1, wherein the at least one arm member is hingedly coupled to the elongate shaft.

3. The suturing device according to claim 1, wherein the trajectory guide defines first and second bores therethrough.

4. The suturing device according to claim 3, wherein at least one of the first or second bores extends obliquely with respect to the longitudinal axis.

5. The suturing device according to claim 3, wherein proximal ends of the first and second bores diametrically oppose each other.

6. The suturing device according to claim 3, wherein the at least one arm member includes an attaching member configured to releasably retain a suture.

7. The suturing device according to claim 6, wherein at least one of the first or second bores is aligned with the attaching member when the at least one arm member is in the second position.

8. The suturing device according to claim 6, further comprising a mesh disposed on a distal surface of the at least one arm member when the at least one arm member is in the second position.

9. The suturing device according to claim 1, wherein the trajectory guide includes a locking mechanism for securely anchoring the trajectory guide in a position along the elongate shaft.
