摘要： Described here are devices, systems, and methods for forming a fistula between two blood vessels. Generally, the systems may comprise a first catheter and a second catheter, which may comprise one or more fistula-forming elements. The first and second catheters may comprise one or more magnets, which may be used to assist in bringing the first and catheters in closer proximity to facilitate fistula formation. In some variations, the magnet may have a plurality of magnetic domains each characterized by a magnetic flux vector, with the magnetic flux vectors of the magnet passing through a common magnetic origin.

摘要： Described herein are cryolipolysis devices, systems, and methods for facilitating percutaneous access to a target blood vessel by performing cryolipolysis on subcutaneous adipose tissue obscuring the target blood vessel (e.g., a vessel used for hemodialysis treatment). Generally, the devices include a cooling member carrying a coolant that cools a selected portion of adipose tissue overlying the target blood vessel to reduce the selected portion of adipose tissue, thereby forming a depression in the adipose tissue and allowing the target blood vessel closer to the surface of the skin. In some variations, the cooling member is placed subcutaneously to directly cool the selected portion of adipose tissue. In other variations, the cooling member is placed external to the patient to indirectly cool the selected portion of adipose tissue through the skin.
摘要翻译：本文描述的是溶脂分解装置，系统和方法，用于通过对掩盖目标血管（例如，用于血液透析治疗的血管）的皮下脂肪组织进行冷冻脂解来促进经皮进入目标血管。通常，所述装置包括一个冷却部件，该冷却部件承载着冷却所述部分脂肪组织以覆盖目标血管以减少所选择的部分脂肪组织，由此在脂肪组织中形成凹陷，并允许目标血管更靠近皮肤表面。在一些变型中，将冷却构件皮下放置以直接冷却脂肪组织的选定部分。在其它变型中，将冷却构件放置在患者的外部，以通过皮肤间接地冷却脂肪组织的选定部分。

摘要： Described here are devices, systems, and methods for forming a fistula between two blood vessels. Generally, the systems may comprise a first catheter and a second catheter, which may comprise one or more fistula- forming elements. The first and second catheters may comprise one or more magnetic elements, which may be used to assist in bringing the first and catheters in closer proximity to facilitate fistula formation. In some variations, the magnetic elements may have magnetization patterns such that the flux generated by the magnetic elements is locally concentrated. In some instances, the system may comprise a magnetic control device, which may comprise a magnet, and may be used to increase or create an attractive force between the first and second catheters.
