Abstract: Medical devices, systems, and methods for pain management and other applications may apply cooling with at least one probe inserted through an exposed skin surface of skin. The cooling may remodel one or more target tissues so as to effect a desired change in composition of the target tissue and/or a change in its behavior, often to interfere with transmission of pain signals along sensory nerves. Alternative embodiments may interfere with the function of motor nerves, the function of contractile muscles, and/or some other tissue included in the contractile function chain so as to inhibit muscle contraction and thereby alleviate associated pain. In some embodiments, other sources of pain such as components of the spine (optionally including herniated disks) may be treated.

Abstract: The present invention generally provides improved medical devices, systems, and methods. Embodiments may be particularly well suited for the treatment of dermatological and/or cosmetic defects, and alternative embodiments may be configured for treatment of a wide range of target tissues. Some embodiments of the present invention apply cooling with at least one small, tissue-penetrating probe, the probe often comprising a needle having a size suitable for inserting through an exposed surface of the skin of a patient without leaving a visible scar. The cooling may remodel one or more target tissue so as to effect a desired change in a composition of the target tissue and/or a change in its behavior. Exemplary embodiments make use of replaceable needle probes supported by a probe body handle, with small needle probes often being replaced during treatment of a single patient. Unlike the large format cryogenic cooling systems of the past, small cryogenic cooling needle probes may dull or be damaged by insertion.

Abstract: Disclosed herein is a steerable, curvable catheter with one, two, or more ablation elements that can be used for various applications including vertebroplasty. The catheter can include an elongate, tubular body, having a proximal end, a distal end, and a central lumen extending therethrough; a deflectable zone on the distal end of the tubular body, deflectable through an angular range; a handle on the proximal end of the tubular body; and a deflection control on the handle; an energy delivery control on the handle; and one or more energy delivery elements on the distal end of the device for ablating tissue within bone. The energy delivery elements could be RF heating electrodes in a monopole or dipole arrangement although other energy delivery modalities are also contemplated. For example, the energy delivery elements include cryoprobes. Systems and methods involving the ablation catheter are also disclosed.

Abstract: Disclosed herein is a steerable and curvable drill that can be used for various applications including vertebroplasty. The drill can include an elongate, tubular body, having a proximal end, a distal end, and a central lumen extending therethrough; a deflectable zone on the distal end of the tubular body including one or more laser cuts, deflectable through an angular range; an insertable wire insertable into at least a portion of the central lumen of the elongate, tubular body; a handle on the proximal end of the tubular body; a deflection control on the handle; a drill control on the handle; a drive shaft within the elongate tubular body having a proximal end and a distal end; and a boring element on the distal end of the device for creating a cavity within bone. The boring element can be operably connected to the distal end of the drive shaft via a crimping mechanism. Systems and methods involving the drill are also disclosed.

Abstract: Methods and devices for augmenting bone, such as in performing vertebroplasty are disclosed. A bone cement injection needle is provided, having a laterally deflectable distal end. The distal end may be provided with one or two or more cavity creation elements, such as a bevel or diamond tip or inflatable balloons. A cavity creation element may include one or more filament layers. Systems are also disclosed, including the steerable and curvable injection needle, introducer and stylet. The system can also include various exit ports that can be configured with clog-resistant features. Methods are also disclosed.

Abstract: Medical devices, systems, and methods optionally treat dermatological and/or cosmetic defects, and/or a wide range of additional target tissues. Embodiments apply cooling with at least one small, tissue-penetrating probe, the probe often comprising a needle having a size suitable for inserting through an exposed surface of the skin of a patient without leaving a visible scar. Treatment may be applied along most or all of the insertable length of an elongate needle, optionally by introducing cryogenic cooling fluid into the needle lumen through a small, tightly-toleranced lumen of a fused silica fluid supply tube, with the supply tube lumen often metering the cooling fluid. Treatment temperature and/or time control may be enhanced using a simple pressure relief valve coupled to the needle lumen via a limited total exhaust volume space.

Abstract: This relates to methods and devices for treating reversible chronic obstructive pulmonary disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airway of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the air ways to constrict and/or reduces the resistance within the airway to the flow of air through the airway. This also relates to a method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airway to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter.

Abstract: Methods are provided for treating collapsed bronchial tubes found in patients with chronic obstructive pulmonary diseases, such as asthma. The method includes heating the bronchial tube to cause tissue in the wall of the bronchial tube to undergo a structural transformation effective to render the wall capable of supporting a non-collapsed lumen. The procedure effectively reinforces the structural integrity of the bronchial tube wall and thereby prevents the lumen from collapsing.
