Abstract
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 two or more components that each include apertures through which a needle can be placed. The handle can be manipulated to align or offset the apertures with respect to each other to modify a clearance through the apertures and selectively engage or disengage the needle or thread.
Claims20
A thread insertion assembly comprising:
- a first butterfly mechanism comprising a first wing, a first pivot component, and a first knuckle portion, the first knuckle portion comprising a first aperture extending therethrough;
- and
- a second butterfly mechanism comprising a second wing, a second pivot component, and a second knuckle portion, the second knuckle portion comprising a second aperture extending therethrough, the first and second pivot components being aligned along a pivot axis to permit the first butterfly mechanism to pivot relative to the second butterfly mechanism, the first and second butterfly mechanisms being pivotable between (i) a first position in which central axes the first and second apertures are coaxially aligned with respect to each other to permit a trocar to move through the first and second apertures relative to the assembly and (ii) a second position in which the central axes of the first and second apertures are misaligned with respect to each other to engage a trocar positioned through the first and second apertures to restrict movement of the trocar relative to the assembly.
A method of inserting a thread comprising positioning a portion of a trocar into a first passage of a first arm and into a second passage of a second arm, the first and second arms being rotatable about a longitudinal axis;
- biasing the first and second arms to rotate the first and second arms about the longitudinal axis to engage the trocar positioned within the first and second passages;
- inserting a distal portion of a trocar into a patient;
- releasing the portion of the trocar to permit movement of the trocar relative to the first and second arms is permitted;
- and retracting the handle relative to the patient.
