A system of devices for treating an artery includes an arterial access sheath adapted to introduce an interventional catheter into an artery and an elongated dilator positionable within the internal lumen of the sheath body. The system also includes a catheter formed of an elongated catheter body sized and shaped to be introduced via a carotid artery access site into a common carotid artery through the internal lumen of the arterial access sheath. The catheter has an overall length and a distal most section length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.

A thrombus treatment platform comprises an aspiration catheter, an aspiration pump, a stirring device and a filter assembly, the filter assembly comprises a filter rod and a filter screen; the stirring device comprises a first catheter, a second catheter, a stirrer and an operating device capable of causing the first catheter and the second catheter to slide relatively so that the stirrer can be switched between the expanded state and the collapsed state; the thrombus treatment platform further comprises a driving device capable of driving the rotation of the stirrer. The present disclosure can remove thrombus under the condition of ensuring relative safety, and is particularly suitable for removing a large number of thrombus in the inferior vena cava, protects venous valves and venous vessel walls, has controllable blood loss and simple operation steps, shortens operation time, and reduces patient hospitalization expenses.

A transseptal system includes a needle, a guidewire, a handle, and a dilator. The handle defines a needle passage to slidably receive the needle, and a guidewire passage to slidably receive the guidewire. The dilator defines a lumen having a distal region and a proximal region. The dilator is coupled to the handle such that the lumen is open to the needle passage and the guidewire passage. The proximal region of the lumen is sized to simultaneously receive the needle body and the guidewire. The distal region is sized to slidably receive one of the needle and the guidewire on an individual basis. A transseptal puncture and access procedure can be performed, including puncturing tissue with the needle followed by immediate advancement of the guidewire into the accessed area, eliminating the need for multiple instrument exchanges during the procedure.

An interventional catheter for treating an artery includes an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck. The elongated body has an overall length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.

The present disclosure relates generally to dual-function medical devices with diagnostic and therapeutic capabilities, such as real-time visualization and ablation. Many embodiments may include an ergonomic handle and dual-lumen catheter configured for dual-function diagnostic and therapeutic use during a medical procedure, such as a duodenoscope. The medical device may be delivered within an endoscope working channel to provide real-time visualization (e.g., radial ultrasound imaging) and treatment (e.g., soft tissue ablation) of cancerous tissue. For instance, a first lumen may include a high-frequency linear or radial ultrasound and the second lumen may include a surgical instrument, such as an ablation tool. Some embodiments may include a controller with a feedback loop configured to adjust the therapeutic tool based on data from the diagnostic tool. For instance, the power of an ablation tool may be adjusted by the controller based on data generated by an imaging device.

A benign prostatic hyperplasia treatment device. The benign prostatic hyperplasia treatment device includes: an anchor assembly including a pair of first and second anchors arranged at upper and lower portions of the outer surface of the prostate gland, and a ligature connecting the first and second anchors with each other so that the first and second anchors continuously compress the prostatic tissues to secure the opening of the prostatic urethra; a sheath inserted into the urethra and having a needle, which guides the anchor assembly to be deployed at the prostate gland; a needle manipulation part for manipulating movement of the needle so that the needle is deployed through an end portion of the sheath.

A catheter assembly includes a catheter comprising a flexible elongated member including a distal portion that includes a tubular body defining an inner lumen and a plurality of body apertures that extend through a sidewall of the tubular body into the inner lumen, and a plurality of primary electrodes positioned along the tubular body. The catheter assembly includes a wire defining at least one secondary electrode, the wire being configured to be slidably moved through the inner lumen of the tubular body, where the wire and the plurality of primary electrodes are configured to electrically couple to an energy source that delivers an electrical pulse to a fluid in contact with the plurality of primary electrodes and the at least one secondary electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.

A dilator assembly comprising an elongated body having a proximal end and a distal end, a first lumen extending along the body, a second lumen extending along the body so that it is a parallel to the first lumen, and a joint lumen disposed adjacent the distal end of the body, wherein both the first lumen and second lumen are in fluid communication with the joint lumen. A guidewire has a first end and a second end, and the first end of the guidewire is slidably received in the first lumen and the second end of the guidewire is slidably received in the second lumen.

For improved treatment of occlusions, a microcatheter guidewire unit for use in a hollow organ including a catheter body with a distal end, a proximal end, and at least two guidewires with guidewire tips is provided. The first guidewire and/or a tip of the first guidewire has a higher rigidity than a second guidewire and/or a tip of the second guidewire. The first guidewire and the second guidewire are passed through the catheter body and arranged such that the tip of the first guidewire and the tip of the second guidewire may be advanced or retracted independently of one another along longitudinal axes.
