Abstract
Catheter systems of the invention involve guided and informed dissolution of occlusions in blood vessels. According to certain aspects, a catheter system of the invention includes an elongate body defining a first lumen and comprising a distal portion, an inner member configured for insertion into the first lumen, the inner member comprising an energy source configured to deliver therapeutic energy to a treatment site, and an imaging assembly located at the distal portion of the elongate body. In some embodiments, the catheter system includes a functional flow sensor in addition to or as an alternative to the imaging assembly.
Claims23
A catheter system for evaluating a body lumen and delivering therapy thereto, the catheter system comprising:
- an elongate body comprising a distal portion, wherein the elongate body is insertable into the body lumen until the distal portion of the elongate body is distal to a treatment site within the body lumen, the elongate body having a central lumen and a plurality of delivery lumens encircling the central lumen on the distal portion of the elongate body;
- an inner member configured for insertion into the central lumen, the inner member being movable within the central lumen, the inner member comprising an energy source configured to deliver therapeutic energy to the treatment site near the distal end of the elongate body;
- and
- an imaging assembly located on the distal portion of the elongate body and on an exterior of the inner member, wherein the imaging assembly is configured to image the treatment site from inside the body lumen while the therapeutic energy is delivered to the treatment site.
A method for evaluating a blood vessel and delivering a therapy to a treatment site of the blood vessel, the method comprising:
- providing a catheter system comprising:
- an elongate body comprising a distal portion, wherein the elongate body is insertable into the body lumen until the distal portion of the elongate body is distal to the treatment site, the elongate body defining a central lumen and a plurality of delivery lumens configured to encircle the central lumen on the distal portion of the elongate body;
- and
- an inner member moveably disposed within the central lumen, the inner member comprising a body with an energy source disposed within the body, the energy source being configured to deliver therapeutic energy to the treatment site when the inner member is inserted into the central lumen of the elongate body;
- and
- an imaging assembly located on the distal portion of the elongate body and on an exterior of the body of the inner member;
- initially introducing the elongate body of the catheter system into the blood vessel and advancing the elongate body until the imaging assembly is distal to the treatment site;
- imaging biological material within the blood vessel with the imaging assembly;
- and
- delivering, with the energy source, therapeutic energy to the biological material, wherein the imaging assembly is configured to image the treatment site from inside the blood vessel while the therapeutic energy is delivered to the treatment site.
A catheter system for evaluating a body lumen and delivering therapy thereto, the catheter system comprising:
- a tubular body comprising a distal portion, wherein the tubular body is insertable into the body lumen until the distal portion of the tubular body is distal to a treatment site within the body lumen the tubular body having a central lumen and at least three delivery lumens encircling the central lumen on the distal portion of the elongate body, the delivery lumens being evenly spaced around a circumference of the tubular body;
- an inner member configured for insertion into the first lumen, the inner member comprising an energy source configured to deliver therapeutic energy to the treatment site near the distal end of the tubular body;
- and
- an imaging assembly located on the distal portion of the tubular body and on an exterior of the inner member, wherein the imaging assembly is configured to image the treatment site from inside the body lumen while the therapeutic energy is delivered to the treatment site.
