Devices, systems, and methods for evaluating a vessel and tracking progression of an intravascular procedure are disclosed. In an embodiment, a medical system is disclosed. One embodiment of the medical system comprises a medical processing unit in communication with an intravascular device configured to obtain intravascular ultrasound (IVUS) data and with an external ultrasound device configured to obtain external ultrasound data. The medical processing unit is configured to receive the IVUS data from the intravascular device, wherein the intravascular device is positioned proximate to an aneurysm, receive the external ultrasound data from the external ultrasound device, wherein the external ultrasound device is positioned to image the aneurysm, and track progression of a coil embolization of the aneurysm based on the IVUS data and the external ultrasound data.

IVUS and external imaging to map aneurysm to determine placement of coils and likelihood of success

Systems, devices, and methods for using an intraluminal sensing device are provided. The intraluminal sensing device may include a ferrous element disposed at a distal portion of an elongate flexible member configured to be placed in a body lumen of a patient. An external electromagnetic field device may be used to produce an electromagnetic field that may be used to direct the movement of the flexible elongate member within the body lumen.

Electromagnetic control for intraluminal sensing devices and associated devices, systems, and methods

Intravascular ultrasound (IVUS) imaging devices, systems, and method are provided. In one embodiment, an IVUS imaging device includes a flexible elongate member configured to be positioned within a lumen of a patient, the flexible elongate member comprising a proximal portion and a distal portion; and an imaging assembly disposed at the distal portion of the flexible elongate member. The imaging assembly includes a first ultrasound transducer operating at a first center frequency; and a second ultrasound transducer operating at a second center frequency different from the first center frequency.

Intraluminal imaging devices with multiple center frequencies

The invention provides devices with integrated intravascular imaging and methods for crossing a CTO within the true lumen of a vessel. An interventional catheter with intravascular imaging capabilities can be guided into an affected vessel and to a CTO. An included intravascular imaging device captures a 3D image of the environment. The catheter includes a crossing member that can be extended out from a distal tip of the catheter, causing the crossing member to directly cross through the CTO creating a new channel through the CTO.

Device and methods for crossing occlusions

The invention provides methods and devices for treating liver cirrhosis or portal hypertension by creating an intrahepatic shunt, or new passage, from a portal vein of a patient to a hepatic vein using a device with intravascular imaging capabilities and pressure sensing capabilities or positioning mechanisms. The integration of intravascular imaging aids in the precise placement of the shunt and pressure measurement may verify successful shunt creation. An apparatus may include a catheter with an extended body for insertion into a hepatic vein of a patient, an intravascular imaging device and a needle exit port on the distal portion of the extended body, and a needle disposed within a lumen in the catheter and configured to be pushed out of the exit port and extend away from a side of the extended body, in which the needle includes a pressure sensor.

Devices and methods for intrahepatic shunts

Embolism treatment devices, systems, and methods are provided. In one embodiment, an embolism treatment system includes a flexible elongate member configured to be positioned within a blood vessel of a patient, the flexible elongate member comprising a distal portion and a proximal portion; an ultrasound imaging component positioned at the distal portion and configured to emit ultrasound energy towards a blood clot within the blood vessel and collect an image signal representative of the blood clot; a treatment component positioned at the distal portion and configured to treat the blood clot; and a flow sensing component positioned at the distal portion and configured to determine a blood flow measurement within the blood vessel associated with the blood clot.
