Intravascular devices, systems, and methods are disclosed. In some embodiments, a method of assembling an intravascular device is provided that includes positioning a first tubular member around a plurality of conductors and a core member; advancing a first of the plurality of conductors through an opening of the first tubular member; positioning a first conductive member around the first tubular member; and electrically coupling the first of the plurality of conductors to the first conductive member. In some embodiments, an intravascular device is provided that includes an insulating member positioned around a plurality of conductors and a core member and a conductive member positioned around the insulating member, wherein at least one of the plurality of conductors extends through an opening in the insulating member and is electrically coupled to the first conductive member.

A system for analyzing tissue includes a platform and an optical sensing unit coupled to the platform. The optical sensing unit has a detector and a plurality of light sources surrounding and electrically isolated from the detector. The optical sensing units obtain optical data for tissue analysis.

A medical device deployment system includes a main body and a guidewire capable of being passed through the main body and including a lumen. An optical shape sensing (OSS) system is configured to pass through the lumen in the guidewire. The OSS system is configured to measure shape, position or orientation of an endograft relative to a blood vessel for placement of the endograft.

A system for performing a minimally invasive procedure comprises a flexible catheter with a lumen extending therethrough. The system also comprises an elongate instrument sized for passage through the lumen and an optical coherence tomographic sensor coupled to the elongate instrument. The system also comprises a control system that includes one or more processors. The control system is configured to receive sensor data from the optical coherence tomographic sensor, profile a tissue based on the received sensor data, generate an output signal based on the profiled tissue, and based on receipt of the output signal, generate a command to indicate or affect movement of the elongate instrument.

A system may comprise a first catheter having a first steerable segment and a second catheter disposed within the first catheter. The second catheter may have a second steerable segment. The system may also comprise an imaging element supported at a distal end of the second catheter, a coil reference sensor supported at a distal portion of the second catheter, and a processor in electrical communication with the coil reference sensor. The processor may be configured to determine a position of a distal portion of the first catheter with reference to the coil reference sensor.

An intracranial intervention system comprises a seeker wire and delivery catheter used to navigate and access a target location within the intracranial subarachnoid spaces (ISAS) of a patient. A microcatheter is then advanced through the delivery catheter to perform a therapeutic procedure, such as installing a shunt within the ISAS to drain cerebral-spinal fluid (CSF). The shunt may be configured to drain CSF from a first and second ISAS, and includes a distal portion which extends into the first ISAS via the second ISAS and a dural venus sinus (DVS) of the patient. The shunt has a main body portion positioned and secured within the second ISAS, a distal portion extending into the first ISAS and the main body portion in the second ISAS have CSF intake opening which allow CSF to flow into a shunt lumen and out through an outflow opening positioned in the DVS.

A system includes a processor circuit configured to receive a set of intravascular data from an intravascular sensor at a first location within a blood vessel. The processor circuit simultaneously receives a set of cardiovascular data from a heart monitor. After the intravascular sensor is moved from the first location to a second location, the processor circuit receives an additional set of intravascular data from the intravascular sensor and an additional set of cardiovascular data from the heart monitor. The processor circuit then determines a distance between the first location and the second location and determines a pulse wave velocity associated with the blood flow within the blood vessel based on the sets of intravascular data, the sets of cardiovascular data, and the distance. The processor circuit then outputs the pulse wave velocity to a display.

A system is provided that furnishes expert procedural guidance based upon patient-specific data gained from surgical instruments incorporating sensors on the instrument's working surface, one or more reference sensors placed about the patient, sensors implanted before, during or after the procedure, the patient's personal medical history, and patient status monitoring equipment. Embodiments include a system having a surgical instrument with a sensor for generating a signal indicative of a property of a subject tissue of the patient, which signal is converted into a current dataset and stored. A processor compares the current dataset with other previously stored datasets, and uses the comparison to assess a physical condition of the subject tissue and/or to guide a procedure being performed on the tissue.

Vision systems on catheters, cannulas, or similar devices with guiding lumens include receptors distributed in annular areas around respective lumens. Each of the receptors has a field of view covering only a portion of an object environment, and the field of view of each of the receptors overlaps with at least one of the fields of view of the other receptors. A processing system can receive image data from the receptors of the vision systems and combine the image data to construct a visual representation of the object environment.

Embodiments for crossing an occlusion by controlling a guide with the aid of optical coherence tomography (OCT) data are described. Embodiments include transmitting one or more beams of radiation via one or more waveguides on a flexible substrate within a guide wire. One or more beams of scattered or reflected radiation may be received from a sample via one or more waveguides. Depth-resolved optical data of the sample may be generated based on the received beams of scattered or reflected radiation. The depth-resolved data may be used for determining at least one of a distance between the guide wire and a wall of the artery and a distance between the guide wire and an occlusion within the artery. A position of the guide wire within the artery may then be controlled based on the determined distance or distances.
