Cryolipolysis devices and methods therefor
First Claim
1. A method of facilitating percutaneous access to a target blood vessel in a patient, comprising:
- determining a path of at least a treatment portion of the target blood vessel;
inserting a subcutaneous probe into adipose tissue;
aligning the probe with the treatment portion of the target blood vessel; and
cooling a selected portion of adipose tissue surrounding the probe, thereby forming a depression in the selected portion of adipose tissue overlying the treatment portion of the target blood vessel.

Abstract
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.
