Abstract

In a general aspect, a medical device includes a receiving arm configured to be coupled to at least a portion of an implant, and a clamping arm having a proximal end coupled to the receiving arm and having a track at a distal end of the clamping arm. The medical device also includes a sliding component including a needle and configured to slidably move along the track of the clamping arm.

First claim

What is claimed is:

1. A medical device, comprising:
a receiving arm configured to be coupled to at least a portion of an implant;
a clamping arm having a proximal end portion coupled to the receiving arm and having a track disposed at a distal end portion of the clamping arm; and
a sliding component including a needle, the sliding component configured to slidably move the needle along the track of the clamping arm,
the clamping arm rotatably coupled to the receiving arm, the clamping arm configured to rotate about an axis towards the receiving arm such that a distance between the track of the clamping arm and the receiving arm is decreased,
wherein the needle has a coupling mechanism configured to be coupled to the implant after the sliding component has been moved toward the receiving arm,
the track of the clamping arm configured to move such that the distance between the track and the receiving arm is increased after the coupling mechanism of the needle has been coupled to the implant.

2. The medical device of claim 1 , wherein the clamping arm has an indicator configured to represent a distance between at least a portion of the receiving arm and at least a portion of the clamping arm.

3. The medical device of claim 1 , wherein the receiving arm has a coupling mechanism configured to be releasably coupled to the implant.

4. The medical device of claim 1 , wherein the needle defines a lumen therethrough, and the sliding component defines an opening that is in fluid communication with the lumen defined by the needle and configured to receive a fluid to be conveyed through the lumen.

5. The medical device of claim 1 , wherein the track has a concave curvature with an inner surface of a concave portion facing toward the proximal end portion of the clamping arm.

6. The medical device of claim 1 , wherein the clamping arm has a guide defining a lumen, the needle configured to slidably move within the lumen when the sliding component is slidably moved along the track of the clamping arm.

7. The medical device of claim 1 , wherein the track is configured to rotatably move about the axis towards the receiving arm from a first position with respect to the receiving arm to a second position with respect to the receiving arm when the clamping arm is rotated towards the receiving arm,
the sliding component is configured to slidably move along the track when the track is in the first position with respect to the receiving arm and configured to slidably move along the track when the track is in the second position with respect to the receiving arm.

8. The medical device of claim 1 , wherein the clamping arm has a proximal end portion and a distal end portion, the proximal end portion of the clamping arm rotatably coupled to the proximal end portion of the receiving arm via a hinge.

9. The medical device of claim 1 , wherein the receiving arm is configured to be inserted into a body of a patient after the receiving arm is coupled to the at least the portion of the implant.

10. The medical device of claim 1 , wherein the clamping arm includes a side protrusion having a rough portion and a smooth portion.

11. A medical device, comprising:
a receiving arm configured to receive at least a portion of an implant;
a clamping arm rotatably coupled to the receiving arm, the clamping arm defining a track, the track configured to rotate about an axis towards the receiving arm such that a distance between the track and the receiving arm is decreased; and
a sliding component including a needle, the sliding component configured to slidably move the needle along the track such that the needle is moved toward the receiving arm,
wherein the needle has a coupling mechanism configured to be coupled to the implant after the sliding component has been moved toward the receiving arm,
the clamping arm configured to move the track such that the distance between the track and the receiving arm is increased after the coupling mechanism of the needle has been coupled to the implant.

12. The medical device of claim 11 , wherein the track is a first track, at least one of the clamping arm or the receiving arm is configured to slidably move along a second track such that the distance between the first track and the receiving arm is decreased.

13. The medical device of claim 11 , wherein the sliding component is configured to slidably move when the distance between the track and the receiving arm is decreased.

14. The medical device of claim 11 , further comprising:
a locking mechanism configured to removably lock the clamping arm in a position with respect to the receiving arm after the distance between the track and the receiving arm has been decreased.

15. The medical device of claim 11 , further comprising:
an indicator mechanism configured to indicate a target position of the sliding component so that at least a portion of the needle is in contact with the implant when the sliding component is slidably moved along the track to the target position.

16. The medical device of claim 11 , wherein the receiving arm is configured to be inserted into a vaginal region of a patient before the clamping arm is moved, the needle configured to pierce a skin tissue of the patient when the needle is moved toward the receiving arm.

17. The medical device of claim 11 , wherein the needle is configured to pierce a tissue of a patient and to be coupled to the implant as the needle is moved toward the receiving arm,
the sliding component configured to slidably move along the track away from the receiving arm such that the implant is pulled through the tissue of the patient after the needle has been coupled to implant.

18. A method, comprising:
inserting at least a portion of a receiving arm of a medical device coupled to at least a portion of an implant into a body of a patient;
moving a clamping arm rotatably coupled to the receiving arm towards the receiving arm, the clamping arm having a track;
rotating the track about an axis towards the receiving arm when the clamping arm is moved towards the receiving arm;
moving a portion of a needle of a sliding component into the body of the patient by moving the sliding component coupled to the clamping arm in a first direction along the track of the clamping arm, the needle having a coupling mechanism that couples to the implant after the sliding component has been moved toward the receiving arm; and
increasing the distance between the track and the receiving arm by moving the track of the clamping arm and after the coupling mechanism of the needle has been coupled to the implant.

19. The method of claim 18 , further comprising:
moving the sliding component in a second direction along the track away from the receiving arm until the portion of the implant coupled to the needle of the sliding component is moved outside of the body of the patient.
