Devices and methods for inserting an implant into skin or other tissue of a patient can include an insertion device having moveable portions that can retain, move, or otherwise control engagement and injection of a hyaluronic thread. The device can include a tubular member and a handle. The handle can include a body component coupled to the tubular member. The body component can include a passage that extends in communication with the lumen. The handle can further comprise first and second arms coupled to the body component and extending outwardly from the distal portion of the tubular member. Based on the configuration, the first and second arms can be positioned along the passage to change a cross-sectional profile of the passage and permit the device to engage or disengage the thread.

1. A thread insertion assembly comprising: a tubular member comprising a proximal portion, a distal portion, and a lumen extending between the proximal and distal portions;a handle coupled to the tubular member distal portion, the handle comprising a passage that extends in communication with the lumen and a moveable arm having an inner surface forming a portion of the passage, the moveable arm having (i) a first position in which the inner surface of the arm is positioned along the passage to define a first cross-sectional clearance and (ii) a second position in which a portion of the arm extends along the passage to define a second cross-sectional clearance, different from the first cross-sectional clearance, to change a cross-sectional profile of the passage anda trocar positioned within the passage, wherein, in the first position, the handle is proximally slideable relative to the trocar to separate the handle from the trocar, and in the second position, the arm is engaged against the trocar to resist movement of the trocar relative to the handle. 2. The thread insertion assembly of claim 1, wherein the arm is pivotably coupled to the handle. 3. The thread insertion assembly of claim 1, wherein the arm and the handle are formed as a single, continuous structure. 4. The thread insertion assembly of claim 1, wherein the arm is pivotably coupled to the handle by a living hinge. 5. The thread insertion assembly of claim 1, wherein the inner surface of the arm comprises a concave surface. 6. The thread insertion assembly of claim 1, comprising a thread coupled to the trocar, wherein the thread extends along the proximal portion of the tubular member. 7. The thread insertion assembly of claim 6, wherein a distal end portion of the thread is coupled to a proximal portion of the trocar. 8. The thread insertion assembly of claim 1, wherein the arm comprises a distal portion of the handle. 9. The thread insertion assembly of claim 1, wherein, in the second position, the trocar is compressed between the arm and an inner surface of the handle forming the passage. 10. A method of inserting a thread comprising: providing a tubular member comprising a proximal portion, a distal portion, and a lumen extending between the proximal and distal portions, a handle coupled to the tubular member distal portion, the handle comprising a passage that extends in communication with the lumen and a moveable arm having an inner surface forming a portion of the passage, the moveable arm having (i) a first position in which the inner surface of the arm is positioned along the passage to define a first cross-sectional clearance and (ii) a second position in which a portion of the arm extends along the passage to define a second cross-sectional clearance, different from the first cross-sectional clearance, to change a cross-sectional profile of the passage, and a trocar positioned within the passage, wherein, in the first position, the handle is proximally slideable relative to the trocar to separate the handle from the trocar, and in the second position, the arm is engaged against the trocar to resist movement of the trocar relative to the handle;positioning the trocar within the handle passage while the moveable arm is in the first position;moving the moveable arm to the second position to engage the trocar relative to the handle;inserting the trocar into a patient;releasing the moveable arm from the second position to release the trocar to permit movement of the trocar relative to the handle; andproximally retracting the handle relative to the trocar and the patient to separate the handle from the trocar. 11. The method of claim 10, comprising positioning the trocar within the handle such that the distal portion of the trocar extends from the handle. 12. The method of claim 10, wherein inserting a portion of the trocar into a patient comprises moving the handle toward the patient. 13. The method of claim 10, wherein biasing the arm toward the passage comprises compressing the trocar between the arm and an inner surface of the handle forming the passage. 14. The method of claim 10, wherein inserting a distal portion of the trocar into a patient comprises distally moving a thread coupled to the trocar. 15. The method of claim 10, wherein proximally retracting the handle comprises separating the thread from the handle from the trocar.
