Abstract
A medical device may include a spool element, including a channel to receive or store a coiled element, and a handle element. The handle element may be coupled to the spool element and include a lumen that at least partially opens into the channel. The medical device may also include an introducer element coupled to the handle, and relative rotation of the spool element and the handle element may dispense or retract the coiled element from the introducer.
Claims20
A medical device, comprising:
- a spool element, including a channel to receive or store a coiled element, and at least one catch that forms a lock for the coiled element between the catch and an edge of the channel, wherein a proximal end of the coiled element is positioned between the catch and the edge of the channel;
- a handle element, wherein the handle element is coupled to the spool element and includes a lumen that at least partially opens into the channel;
- and
- an introducer coupled to the handle,
- wherein relative rotation of the spool element and the handle element dispenses or retracts the coiled element from the introducer.

A medical device, comprising:
- a spool element, including a channel formed by an inner rim and an outer rim;
- and
- a handle element, including at least one cover portion, wherein the at least one cover portion includes at least one extension portion extending into the channel and abutting the inner rim or the outer rim to couple the handle element to the spool, and wherein the handle element includes a lumen that at least partially opens into the channel;
- and
- an introducer coupled to the handle element,
- wherein the outer rim includes at least one slit extending along a portion of the outer rim transverse to the circumference of the outer rim, and
- wherein the handle element includes a guide element extending from the lumen and into the channel between the inner rim and the outer rim to guide a coiled element within the channel into the introducer.

A medical device, comprising:
- an optical fiber;
- a spooler operably coupled to a ratcheting lever and including a circular extension with a spooler hole extending therethrough;
- a disc including a toothed edge and a central pin, wherein the disc is engageable with the ratcheting lever, and wherein the central pin includes a central hole passing through the central pin;
- a return spring positioned within the circular extension positioned between the spooler and the central pin;
- wherein the optical fiber is looped around an external portion of the disc, and wherein a portion of the optical fiber passes through the spooler hole and the central hole.
