Problems solved by technology

If a clot blocks the tip of the catheter, there is a risk that the clot may be inadvertently released during removal of the catheter so that the clot could become an embolism that travels through the bloodstream and blocks a vessel in another part of the animal

example 1

[0217]One example of the manner in which the techniques described herein may be used is an invasive smart guidewire. Invasive guidewires can be used to pass through the vascular system. Using the sensors and analytical techniques described herein, an invasive guidewire can characterize the tissue / substance in contact with it and communicate the characteristics of that tissue / substance to the clinician. Invasive guidewires can also help additional devices reach the interventional site in the patient.

[0218] In this example, the guidewire includes a sensor (preferably an EIS sensor), an impedance spectrometer and a handle. The guidewire may also include additional components that can be inserted along its length during use. Sensors can be used to sense and characterize properties of tissue / substance in contact with it. For example, when used with an impedance spectrometer to perform high frequency impedance measurements, the sensor can be used to determine tissue / substance ...

example 2

[0221] Clinicians can use the guidewire described in Example 1 to determine the best treatment strategy for patients with blocked arteries. Clinicians are able to use the guidewire to characterize the tissue / substance blocking the artery and then choose between different possible treatment options based on this information. In some embodiments, the guidewire may provide treatment recommendations to the clinician based on one or more characterizations it has performed, and optionally, based on data from previous treatments performed with the guidewire.

[0222] In this example, a clinician can use a guidewire to assess and treat arterial lesions. The clinician can first steer the guidewire to the thrombus site, optionally with a handle, and then penetrate the thrombus. Next, the clinician can use the guidewire to measure the composition of the blood clot and / or the tissue / material that is blocking the artery. The clinician can then determine the best treatment for the blocked...

example 3

[0226] Another example of a device that can be used in accordance with the techniques described herein is a smart stent-retriever. Stent-retrievers can be used to remove blood clots from patients. Using the sensors and analytical techniques described herein, the invasive stent-retriever can characterize the clot it contacts and convey the characteristics of the tissue / substance to the clinician.

[0227] In this example, the stent-extractor comprises at least one sensor (preferably at least one EIS sensor and / or EIT sensor), a measuring unit and a handle. The stent-retriever may include sensors at key locations so that information about the clot can be obtained from locations within the clot that come into contact with it. When the stent-retriever includes more than one sensor, the sensors are capable of sensing different properties of the clot in contact with it. For example, the stent-retriever can include one or more sensors capable of sensing the binding of the clot to t...

Abstract

Embodiments described relate to a medical device including an invasive probe that, when inserted into an animal (e.g., a human or non-human animal, including a human or non-human mammal), may aid in diagnosing and / or treating a lesion of the animal (e.g., a growth or deposit within vasculature that fully or partially blocks the vasculature). The invasive probe may have one or more sensors to sensecharacteristics of the lesion, including by detecting one or more characteristics of tissues and / or biological materials of the lesion. The medical device may be configured to analyze the characteristics of a lesion and, based on the analysis, provide treatment recommendations to a clinician. Such treatment recommendations may include a manner in which to treat a lesion, such as which treatment to use to treat a lesion and / or a manner in which to use a treatment device.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] U.S. Provisional Patent Application Serial No. 62, entitled "Medical device making treatment recommendations based on sensed characteristics of a lesion of a duct", filed on April 11, 2016, pursuant to the requirements of 35 U.S.C. §119(e) / 321,001, the contents of which are incorporated herein in their entirety. Background technique [0003] Blockage of blood vessels, including veins or arteries, can occur in various parts of animals (eg, humans or non-human animals) and can have serious consequences. For example, in an ischemic stroke, a blood clot completely or partially blocks blood flow in an artery in the brain. If the clot is not treated quickly, the lack of blood flow can cause irreparable damage to the brain. [0004] The blockage may be caused by a blood clot, which may be caused by the clotting of red and / or white blood cells and / or platelets within the blood vessel. Clotting can be triggered by a variety of...
