The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to delivery systems and methods for coagulating sites of bleeding within mucosal tissues, and in particular, for eradicating esophageal varices.

This disclosure relates generally to treatment programs utilizing expansion elements, such as those associated with occlusion and therapeutic agent delivery devices, systems, and methods. In some more specific examples, treatment programs include expansion-contraction cycles at a pre-selected frequency profile configured to treat a particular condition, such as calcification of an arterial conduit, for example.

There is provided a system for cardiac electromagnetic/magnetic catheterization for diagnosing and treating blood vessels of a patient. The system having at least one electromagnetic intraluminal capsule able to force its way through a narrowing blood vessel, the capsule carrying a camera allowing visualization of blood vessels of a patient. There is a portable electromagnetic tip, where the tip pulls the electromagnetic capsule by electromagnetic force, and when the magnetic tip moves along a body of a patient and pulls the intraluminal electromagnetic capsule along with it towards a narrowing blood vessel visualized by the camera, so that the capsule then treats the narrowing site and clears the blood vessel from coronary plaque. In addition working capsule can replace diseased valve in any cardiac position for either temporary or permanent needs.

Described here are methods and apparatuses for tracking a clot material within a lumen of a suction catheter. For example, an apparatus as described herein may include a flexible elongate body having a suction lumen, a first pair of electrodes within the suction lumen, a second pair of electrodes proximal to the first pair of electrodes, and a controller configured to track a clot material within the suction lumen based on signals from the first pair of electrodes and the second pair of electrodes.

The present disclosure provides a system for delivery of therapeutic energy. The system includes an energy unit configured to convert the acoustic energy signals transmitted to therapeutic ultrasound directed to fragment tumors and carcinogenic tissue in the body. The system also includes an energy unit configured to convert the acoustic energy signal transmitted from the energy unit to ultrasonic energy to image and monitor the treatment site with ultrasound. The system also includes a control unit including a computer for data storage and display.

A medical system may include an insertion device having a handle, a shaft coupled to the handle of the insertion device, and a port positioned on the handle of the insertion device. The port may be in fluid communication with a working channel of the shaft. The port may be a female luer port. The medical system may further include a medical device having a control member terminating in an end effector, a handle having a plurality of circumferential slots along the length of the handle, and a plunger moveable along a longitudinal axis of the handle of the medical device between a first position and a second position. In the first position, the end effector may be positioned within the shaft, and in the second position, the end effector may be positioned distally of the shaft.

Methods and devices are configured for neurointerventional procedures. The methods and devices enable safe and rapid access to the cerebral or intracranial arteries for the introduction of interventional devices such as to treat stroke and/or other disease conditions. The methods and devices include a vascular access and retrograde flow system that can be used safely and rapidly in the neurointerventional procedures.

A path preparation system for preparing a path for a device. The path preparation system includes an ultrasound transmitter and a tracking system. The tracking system is configured to determine a current position of the device on the path. The ultrasound transmitter is configured to focus an ultrasound wave onto a focus position that lies in front of the device in the direction of the path, in spatial relation to the current position of the device.

Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.
