Title:
REMOTE ACCESS VASCULAR AND SOFT TISSUE TUNNELING DILATOR SYSTEMS AND METHODS OF USE
Document Type and Number:
WIPO Patent Application WO/2021/003056
Kind Code:
A3
Abstract:
Remote access, soft tissue tunneling dilators are used for the placement of central venous catheters of varying sizes into one or more jugular veins, for forming pathways of varying sizes through subcutaneous soft tissue, or for enlarging internal renal access pathways of varying sizes to accommodate access by urological instruments. Dilators comprise a tapered body extending from a proximal end to a distal tip, where both an outer diameter and a material hardness of the tapered body gradually increase distally-to-proximally from the distal tip toward the proximal end of the tapered body. The tapered body may include a plurality of visual indicators disposed upon the body at one or both of a plurality of distally-to-proximally increasing length increments and a plurality of distally-to-proximally increasing diameter increments. Other embodiments are also disclosed.
