LUMEN-MEASURING DEVICES AND METHOD

摘要

The present invention provides a lumen measuring device and method that allows the user to calculate the exact length and diameter of a suitable interventional prosthesis as well as the height and length of stenosis during the same exploratory procedure. One embodiment of the invention includes a measurement assembly (240) comprising at least two legs (250, 300) having distal (260, 310) and proximal (270, 320) ends and inward facing (280, 330) and lumen facing (290, 340) surfaces. The legs are coupled with each other at proximal and distal ends thereof and have measurement markings (350, 360) on the lumen facing surfaces thereof, so that measurement of the target site takes place between the distal and proximal ends of the legs.
