Abstract
Described herein are methods and apparatuses for characterizing a material at a distal end of an aspiration catheter using one or more sensors. The methods and apparatuses described herein may include a plurality of sensing electrodes at a distal end region of the apparatus, and a controller configured to sense contact and/or close proximity to the sensing electrodes. These methods and apparatuses may determine or detect vessel size. These methods and apparatuses may include distal contrast ports for applying contrast material distal to the aspiration catheter. In some examples these apparatuses include one or more reference electrodes near the sensing electrodes that may enhance detection of material (e.g., clot, blood vessel wall). These methods and apparatuses may include a steerable distal end region. In some cases the apparatuses and methods may include a retriever probe to assist in capturing clot material.
