The present invention generally relates to improved medical devices, systems, and methods. In many embodiments, devices, systems, and methods for locating and treating a target nerve with integrated cold therapy and electrical stimulation systems are provided. For example, nerve stimulation and cryoneurolysis may be delivered concurrently or alternately with the cryo-stimulation device. In some embodiments, the device may be operated by a single operator or clinician. Accordingly, embodiments of the present disclosure may improve nerve targeting during cryoneurolysis procedures. Improvements in nerve localization and targeting may increase treatment accuracy, physician confidence in needle placement during treatment, and clinical efficacy and safety. In turn, such improvements may decrease overall treatment times, the number of repeat treatments, and the re-treatment rate. Further, additional improvements in nerve localization and targeting may reduce the number of needle insertions, applied treatment cycles, and may also reduce the number of cartridge changes.

Disclosed are devices, a systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various locations within the associated chamber of the heart.

Compositions and formulations for use with devices and systems that enable tissue cooling, such as cryotherapy applications, for alteration and reduction of adipose tissue are described. Aspects of the technology are further directed to methods, compositions and devices that provide protection of non-targeted cells (e.g., non-lipid-rich cells) from freeze damage during dermatological and related aesthetic procedures that require sustained exposure to cold temperatures. Further aspects of the technology include systems for enhancing sustained and/or replenishing release of cryoprotectant to a treatment site prior to and during cooling applications.

A method for the treatment of a patient for the purpose of lowering blood pressure and/or treating other medical conditions such as cardiac arrhythmias. A catheter having an ablation element is placed inside the body of a patient and is directed to a targeted location either on in the abdominal aorta where the right or left renal arteries branch from the aorta at or near the superior junction or ostia or on the inside of the inferior vena cava near the junction with the right renal vein or in the left renal vein at a position spatially near where the left renal artery branches from the abdominal aorta. Catheters designed for use in the method where these targeted locations are also disclosed and claimed.

An elongate medical device having a device longitudinal axis and a device distal region, the medical device comprising a balloon at the device distal region and having a balloon longitudinal axis, the balloon comprising a balloon inflatable portion with a first length configured to transition from a deflated state to an inflated state and includes a portion of the balloon proximal portion and a portion of the balloon distal portion, a balloon proximal portion with a second length, a balloon distal portion with a third length, wherein, in the inflated state, the balloon is symmetrical about the balloon longitudinal axis and the balloon comprises a first profile shape with a second length and a second profile shape with a third length, and wherein the balloon distal portion comprising the second profile shape comprises a tissue contacting surface where a substantial portion of the tissue contacting surface is concave.

A surgical pump assembly includes a motor configured to provide a motor output, a transmission assembly configured to receive the motor output and provide a plurality of transmission outputs, and a plurality of pumps. Each pump of the plurality of pumps is configured to receive one of the transmission outputs of the plurality of transmission outputs. A surgical generator includes at least one energy module configured to generate an energy-delivery signal, at least one energy port configured to connect to a surgical instrument to deliver the energy-delivery signal thereto, and the surgical pump assembly.

Systems, methods and devices for the treatment of tissue are disclosed. A system includes an elongate tube with a distal portion. A treatment element is positioned on the elongate tube distal portion, the treatment element constructed and arranged to treat target tissue. In one embodiment, gastrointestinal tissue is modified for the treatment of diabetes.

Devices and systems for the selective positioning of an intravascular neuromodulation device are disclosed herein. Such systems can include, for example, an elongated shaft and a therapeutic assembly carried by a distal portion of the elongated shaft. The therapeutic assembly is configured for delivery within a blood vessel. The therapeutic assembly can include one or more energy delivery elements configured to deliver therapeutic energy to nerves proximate a vessel wall.

Apparatus and methods for deactivating pulmonary nerves extending along the main bronchi of a mammalian subject to reduce ARDS effects by advancing an ultrasound transducer into the right and subsequently left main bronchus. The ultrasound transducer emits circumferential ultrasound so as to heat a circumferential tissue volume encompassing the right and left main bronchus. The energy of <10 W acoustic for <5 sec will not be sufficient to cause tissue necrosis but sufficient to inactivate nerve conduction. This treatment can be performed without locating or focusing on individual pulmonary nerves.
