Benefits of technology

The patent describes a method where a cryogenic probe can be used to treat multiple areas of tissue. The method includes relocating the treatment portion of the cryogenic probe to a different area of the tissue, and then activating the cryogenic probe to create a second cooling treatment zone. The advantage of this method is that it allows for more flexibility in the probe, which can improve its insertion force and make it easier to bend around resistance or lateral force. Overall, the patent describes a method for creating multiple cooling treatment zones using a flexible cryogenic probe.

Problems solved by technology

Chronic pain may be particularly disabling, and the cumulative economic impact of chronic pain is huge.
While both these techniques may provide some level of relief, they can have significant drawbacks.
Opiod analgesics can be addictive, and may also of themselves be debilitating.
The analgesic effects provided by pharmaceuticals may be relatively transient, making them cost-prohibitive for the aging population that suffers from chronic pain.
While neurostimulators may be useful for specific applications, they generally involve surgical implantation, an expensive which carries its own risks, side effects, contraindications, on-going maintenance issues, and the like.
Unfortunately, significant volumes of toxins may be used on a regular basis for effective Chemodenervation, and such use of toxins can have significant disadvantages.
It is typically injected into the facial muscles to block muscle contraction, resulting in temporary enervation or paralysis of the muscle.
While BOTOX® and / or mesotherapies may temporarily reduce lines and wrinkles, reduce fat, or provide other cosmetic benefits they are not without their drawbacks, particularly the dangers associated with injection of a known toxic substance into a patient, the potential dangers of injecting unknown and / or untested cocktails, and the like.
Additionally, while the effects of endermology are not known to be potentially dangerous, they are brief and only mildly effective.
Further, there are challenges associated accuracy in finding the appropriate depth of target tissue.

Embodiment Construction

[0048]The present invention provides improved medical devices, systems, and methods. Embodiments of the invention will facilitate remodeling of target tissues disposed at and below the skin, optionally to treat a cosmetic defect, a lesion, a disease state, and / or so as to alter a shape of the overlying skin surface.

[0049]Among the most immediate applications of the present invention may be the amelioration of lines and wrinkles, particularly by inhibiting muscular contractions which are associated with these cosmetic defects so as so improve an appearance of the patient. Rather than relying entirely on a pharmacological toxin or the like to disable muscles so as to induce temporary paralysis, many embodiments of the invention will at least in part employ cold to immobilize muscles. Advantageously, nerves, muscles, and associated tissues may be temporarily immobilized using moderately cold temperatures of 10° C. to −5° C. without permanently disabling the tissue structures. Using an ...

Abstract

A point of incision is created within tissue, the tissue having a temporoparietal fascia-deep temporoparietal fascia layer (TPF-sDTF) beneath skin and a temporal branch of a target nerve extending along a portion of the TPF-sDTF, the point of incision being laterally displaced from the target nerve. A cryogenic probe having a distal tip extending from an elongated body is inserted into the point of incision. The TPF-sDTF is bluntly dissected using the cryogenic probe such that a treating portion of the cryogenic probe is directly adjacent to a first treatment portion of the target nerve. The cryogenic probe is activated to create a first treatment zone at the first treatment portion of the target nerve to cause a therapeutic effect.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 801,268, filed on Mar. 15, 2013, which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]The present invention is generally directed to medical devices, systems, and methods, particularly for cooling-induced remodeling of tissues. Embodiments of the invention include devices, systems, and methods for applying cryogenic cooling to dermatological tissues so as to selectively remodel one or more target tissues along and / or below an exposed surface of the skin. Embodiments may be employed for a variety of cosmetic conditions, optionally by inhibiting undesirable and / or unsightly effects on the skin (such as lines, wrinkles, or cellulite dimples) or on other surrounding tissue. Other embodiments may find use for a wide range of medical indications, for example, such as pain management, movement disorders, surgical methods, and aesthetic treatments. S...
