Problems solved by technology

Importantly, for some pathologies (such as acute ischemic stroke), time to treatment is a key factor in patient prognosis, and in vitro testing may not be a practical way to determine optimal treatment for patients because of the time required for sampling and analysis

Embodiment approach 1

[0093] As a result of the analysis stage 510 an indication of clot composition may be provided which advantageously allows the clot to be classified qualitatively and quantitatively as follows, including excluding the presence of hemorrhagic stroke. Such information can include cellular components, extracellular components, morphology, organization and distribution of components, permeability, adhesion, water content, resistance to degradation, fibrin crosslink density, fiber diameter, modulus, strain, Deformation (e.g. elastic, plastic, viscoelastic), compressive and / or fracture behaviour. An exemplary list of such indicators is provided herein without limitation, and other qualitative and / or quantitative indicators are contemplated for use with the embodiments disclosed herein:

[0094]

[0095] Step 510 may comprise one or a combination of the previously described clot analysis embodiments. For example, step 510 may include analyzing criteria from CT scans and MRI scans...

Abstract

The present invention relates to a method and apparatus for managing an acute ischemic event. The method for managing one or more acute ischemic events can include determining the criteria of a clot;classifying the clot based on the criteria and generating a classification; determining an individualized treatment protocol for the clot based on the classification, the individualized treatment protocol comprising one or more techniques selected from using aspiration, restoring perfusion using a first reperfusion device, and / or restoring perfusion using a second reperfusion device; and treatingthe clot based on the individualized treatment protocol.

Description

technical field [0001] The present disclosure relates to the acute management of ischemic events such as stroke in the hyperacute phase in order to treat the patient and minimize brain damage. Background technique [0002] The World Health Organization estimates that 15,000,000 strokes occur each year. A clot may form locally and block a blood vessel without being released as an embolus—a mechanism that is common in the development of blocked coronary arteries. Acute blockages may include blood clots, misplaced devices, migrated devices, large embolisms of fat or air, etc. Thromboembolism occurs when part or all of the thrombus breaks away from the blood vessel wall. This clot is then transported in the direction of blood flow. Clots can include a range of shapes and consistencies. Long strands of softer clot material may tend to lodge at bifurcations or trifurcations, resulting in multiple vessels being occluded simultaneously over significant lengths. Older clot mater...
