The present disclosure provides a device and a method for cooling living tissues for a medical purpose and other purposes. The cooling device comprises: a container configured to accommodate a cooling medium and thermally coupled with the cooling medium by directly contacting the cooling medium; a cooling generator configured to be thermally coupled with the container by a direct contact and thereby to provide cooling energy to the cooling medium; and a heat sink dissipating heat from the cooling generator, the heat sing being configured to be spaced apart from the cooling generator and to be thermally coupled with the cooling generator without a direct contact with the cooling generator.

A method of treating a subject in need thereof, is carried out by (a) administering said subject a therapeutic intervention (e.g., an active agent) in a treatment effective amount; and concurrently (b) administering said subject caloric vestibular stimulation in a treatment effective amount, said caloric vestibular stimulation administered so as to enhance the efficacy of said active agent. In some embodiments, the caloric vestibular stimulation is administered as an actively controlled time varying waveform.

A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

An IV pole mountable, therapeutic infusate processing device is incorporated into a hypothermia system to receive therapeutic fluid(s), such as normal saline, peritioneal dialysis solution, or other crystalloid solution, to heat such therapeutic fluid(s) a few degrees centigrade above normal body temperature and to direct the resulting heated infusate to and through a selected anatomical portion of a patients body to raise the temperature of that body portion so as to affect any cancerous or other tumors that may be located therein. The processing device is provided with touch screen controls and visual indicators to facilitate its proper use; while the system further includes temperature and pressure sensors to monitor the hyperthermia processing to insure patient safety.

Described here are devices, systems, and methods for treating one or more conditions (such as dry eye) or improving ocular health by providing stimulation to nasal or sinus tissue. Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.

A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes two or more first cut shapes and two or more second cut shapes along a helical path extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions.
