Abstract
A method of detecting and treating a microvascular obstruction is provided. In one embodiment, a catheter is provided for both detecting the microvascular obstruction and treating or removing the obstruction.
Claims20
A method for treating a microvascular obstruction comprising:
- locating a position of said microvascular obstruction within a vasculature of a patient;
- advancing a distal end of a treatment catheter through said vasculature and within proximity of said position of said microvascular obstruction;
- expanding an occlusion member within said vasculature;
- delivering a treatment agent between said expanding occlusion member and said microvascular obstruction;
- and
- monitoring treatment of said microvascular obstruction.
3 more elements
A method for treating an obstruction of a microvascular vessel within a patient, comprising:
- advancing a distal end of a guidewire to a location in communication with said obstruction;
- advancing a distal end of said treatment catheter over said guidewire to said location in communication with said obstruction;
- releasing a treatment agent from said treatment catheter;
- monitoring an impedance of said microvascular vessel;
- stopping said releasing of said treatment agent when said impedance indicates removal of said obstruction.
2 more elements
A system for treating a microvascular obstruction comprising:
- a treatment catheter comprising:
- an expandable occlusion balloon disposed on a distal end of said treatment catheter;
- a first lumen;
- a plurality of diffusion holes in communication with said first lumen and located at said distal end of said treatment catheter;
- and
- a selectively expandable occlusion member disposed at said distal end of said treatment catheter;
- an injector in communication with said first lumen for delivering a treatment agent through said catheter;
- and,
- an occlusion sensor for monitoring a level of blockage by said occlusion.
