SYSTEM AND METHOD FOR ESTABLISHING VASCULAR ACCESS

摘要

Systems, kits, and methods for establishing vascular access are described. A system may include a needle, a radially expandable sleeve and a dilator. The methods include creating an initial tissue tract to a target blood vessel with a radially expandable sleeve mounted on a needle. Upon removal of the needle, the dilator is then passed through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.
