Abstract
Devices and methods for inserting an implant into skin or other tissue of a patient can include a hyaluronic thread coupled with an insertion device that can provide a supportive enclosure for the thread as it is injected into a patient's skin or other tissue. The device can include a moveable member and laterally extending portions, a closed distal portion, and an inner cavity so that the thread can be positioned within the inner cavity and extend along the moveable member. The laterally extending portions can move, relative to the thread, to expose the thread. In use, the moveable member is insertable into a patient and at least a portion of the moveable member is configured to move within a patient to expose the thread.
Claims23
A thread insertion assembly comprising a base and a moveable member having a proximal portion coupled to the base, the movable member extending in a longitudinal direction along a portion of a thread, wherein a portion of the moveable member comprises laterally extending portions that extend in a lateral direction relative to the longitudinal direction to form an enclosure that surrounds at least a portion of a circumference of the thread in a first configuration, and a distal portion of each of the laterally extending portions circumferentially unfolds away from each other and the thread in the lateral direction in a second configuration.
A thread insertion device comprising a moveable member coupled to a base, the movable member extending in a first direction along a longitudinal length of a thread and comprising laterally extending portions extending in a second direction that is different than the first direction, wherein, in a first configuration, distal end portions of the laterally extending portions are positioned adjacent to each other and spaced apart by a first distance to form an enclosure that surrounds at least a portion of a circumference of the thread, and in a second configuration, the distal end portions of the laterally extending portions are spaced apart by a second distance forming an opening along a longitudinal length of the enclosure that exposes the thread from within and along the longitudinal length of the enclosure, wherein the second distance is larger than the first distance.
A method of inserting a thread comprising:
- inserting a distal portion of a moveable member into a patient, in a first configuration, wherein the moveable member is coupled to a base and extends in a longitudinal direction along distal portion of a thread and extends in a lateral direction to form an enclosure that surrounds a circumference of the thread;
- and laterally unfolding distal portions of the laterally extending portion of the moveable member away from each other and the thread in a second configuration to form an opening along a longitudinal length of the enclosure and expose the thread from within and along the longitudinal length of the enclosure.
