The present invention relates to a disposable tongue scraper which has a strong and simple structure, a durable and efficient operation, comparatively inexpensive to manufacture, and a novel combination and arrangement of parts comprising a scraper body that forms a curved shape after bending at an acute angle at a bending point for scraping operation, a pair of handle casings attached with the scraper body, and a storage tissue net attached to the bottom of the scraper body to store the scraped oral wastes and to absorb the oral fluid. The present invention aims to provide the tongue scraper not only utilized for scraping the coating from the tongue, but also for storing the scraped oral wastes and saliva wastes from the mouth to maintain hygiene.

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.

A method is described for performing a percutaneous operation on a patient to remove an object from a cavity within the patient. The method includes advancing a first alignment sensor into the cavity through a patient lumen. The first alignment sensor provides its position and orientation in free space in real time. The alignment sensor is manipulated until it is located in proximity to the object. A percutaneous opening is made in the patient with a surgical tool, where the surgical tool includes a second alignment sensor that provides the position and orientation of the surgical tool in free space in real time. The surgical tool is directed towards the object using data provided by both the first and the second alignment sensors.

The present invention discloses a ball probe ultrasonic bone removal device that is designed to assist surgeons with foraminotomy procedures. The device comprises a shaft at a first end of the device and a spherical ball tip at a second end of the device. In between the shaft and the ball tip is a foot piece that connects to the shaft through an angle. On the foot piece, serrations or a course surface cover a portion of the circumference of the foot piece. In some embodiments, serrations or a course surface may also cover a portion of the circumference of the shaft. The spherical ball tip is smooth and designed to cause no damage to the sensitive nerves and tissue in the intervertebral foramina, but the surface with the serrations or the course protrusions are designed to remove bone and tissue under ultrasonic movement (e.g., vertical vibration, rotational oscillation).

In various embodiments, the present specification discloses an aspiration catheter that has a slim profile, can effectively anchor or self-center in a location, within a patient's vessel lumen, to better provide directed suction or vacuum/negative pressure, and/or can effectively funnel or direct suction or vacuum/negative pressure toward an occlusion or obstruction within the patient's vessel lumen.

The present disclosure relates to a method and a device for treating heart failure by normalizing elevated blood pressure in the left and right atria of a heart of a mammal. The present disclosure includes methods for creating and maintaining an opening in the atrial septum. Tools for making an opening and enlarging the opening are also disclosed. Use of the techniques and tools described herein prolongs the patency of an intra-atrial pressure relief opening.

The disclosure provides plaque treatment catheter assemblies for the treatment of arterial plaques and removal of clots. One assembly includes a second catheter tube movable within a first catheter tube, and an expansion member movable within the second tube. The second catheter tube has one or more distally-disposed and outwardly-expandable plaque treatment portion(s). Another assembly includes a catheter tube and at least one channel(s) within the catheter. The channel includes an elongate member with a distally-disposed plaque scoring or clot retrieval member. Optionally, the assembly includes an expandable member that can cause movement of the scoring member.

A basket apparatus is described that assists in removing objects from within a patient. The apparatus includes a number of pull wires, each pull wire physically coupled to a different capstan that individually actuates one of the pull wires. The apparatus also includes an outer support shaft itself including a number of channels through which the pull wires traverse. The portions of the pull wires extending out of the outer support shaft form a basket of adjustable size, shape, and position. The pull wires are attached together at a tip located at a distal end of the basket apparatus. By controlling the actuation of the various pull wires, the basket's shape, position size can be manipulated to reposition the basket around an object located within a patient, independent of or in conjunction with motion of the remainder of the apparatus or an associated endoscope.

The invention resides in the field of medical technology. It relates in particular to a sonotrode suitable for use with an ultrasonic surgical instrument. The invention refers further to an ultrasonic surgical instrument for cutting or punching bones, including such a sonotrode as well as a method for manufacturing the sonotrode of the invention.
