Abstract
There is provided herein an assemblable cryoneedle for performing a cryo-treatment, particularly but not limited to, for cryo-treatment of keloids and scars. According to some embodiments, the assemblable cryoneedle includes an outer elongated needle having a sealed distal portion, an inner elongated needle, and a connector, configured to connect and allow fluid communication therebetween. The inner elongated needle is configured to be inserted into the outer elongated needle, forming a double lumen configuration. The outer elongated needle is configured to be inserted into a treatment area of a subject.
Claims20
An assemblable cryoneedle comprising:
- an outer elongated needle, configured to be inserted into a treatment area of a subject, the outer elongated needle comprising a sealed distal portion and a proximal portion comprising an opening;
- an inner elongated needle, configured to be inserted into the outer elongated needle, the inner elongated needle comprising:
- a proximal portion, having a proximal opening and configured to be connected to a cryogen source, and
- a distal portion, having a distal opening, wherein the proximal and distal openings of the inner elongated needle define a lumen there between;
- and
- a connector comprising:
- a distal portion having a distal opening;
- a proximal portion having a proximal opening, wherein the connector's proximal and distal openings define a lumen there between;
- and
- an outlet port fluidly connected to the lumen,
- the connector is configured to detachably couple the outer elongated needle with the inner elongated needle,
- wherein the connector is configured to facilitate flow of a cryogen from the proximal portion to the distal portion of the inner elongated needle, back from the sealed distal portion of the outer elongated needle, and out through the outlet port of the connector.
