Abstract
The invention relates to a system, method and device for optically determining the shape and size of a lumen of a vessel or body cavity, and of, for example, a balloon stent as it is inflated. The size and shape determination of the lumen of the vessel or body cavity allows for accurate and safe deployment of a stent within the lumen.
Claims26
A stent delivery system, comprising:
- a catheter having a distal portion and a proximal portion;
- a guidewire removably received within the catheter;
- a plurality of optical emitting fibers for measuring a surrounding area in a lumen wherein the plurality of optical emitting fibers is located on the catheter, the guidewire, or a combination thereof;
- an expandable balloon disposed on the distal portion of the catheter;
- and
- a stent disposed over an expanded portion of the balloon to a position within the measured surrounding area in the lumen.
3 more elements
A method for deploying a stent comprising:
- introducing a stent delivery device into a lumen, wherein the stent delivery device comprises a plurality of optical emitting fibers;
- measuring a surrounding area of the lumen;
- and
- actuating the stent delivery device to deploy a stent to a portion within the measured surrounding area of the lumen.
1 more element
A method of deploying a stent within a lumen, comprising:
- providing a stent delivery system, comprising:
- a guidewire;
- a catheter having a distal portion and a proximal portion;
- a plurality of optical emitting fibers for measuring a surrounding area in the lumen, wherein the plurality of optical emitting fibers is located on the guidewire, the catheter, or a combination thereof;
- a balloon disposed on the distal portion of the catheter;
- and
- a stent disposed over the balloon;
- utilizing the stent delivery system to place the stent at a desired position within the measured surrounding area in the lumen;
- and
- deploying the stent within the measured surrounding area in the lumen.
