| 20110202066 | RETRIEVAL DEVICE MADE OF PRECURSOR ALLOY CABLE - A medical retrieval device for retrieving foreign objects from a patient and the method of constructing the device are disclosed. The device incorporates a wire cable composed of a precursor alloy to a superelastic material to improve durability of the device. Because precursor alloys exhibit, a linear stress-strain relationship and a yield point associated with a relatively high stress level, the device transfers greater stresses before experiencing deformation. Thus, greater crushing forces can be achieved using a device of this type. These crushing forces may be needed when the foreign object is too large to remove intact. This property also facilitates the device in dilating ducts to retrieve foreign objects. Using the precursor alloy additionally eliminates the need for heat treatment of the cables used in constructing the device. A retrieval device made of precursor alloy cable also is less susceptible to permanent deformation and unwinding during use. | 08-18-2011 |

| 20100286708 | System for blood vessels cleaning, such as for a coronary artery, peripheral artery or any other body vessel, based on mobile agent - This paper describes a system and method invention for blood vessels cleaning, such as a coronary artery, peripheral artery, or any other body vascular based on a mobile agent. The system consists of device which is electronically controlled, performing a procedure of vessel walls cleaning by removing the accumulated plaque or any other blockage material. This plaque or other blockage type may cause atherosclerosis and can eventually cause the artery to be blocked, causing heart disease, heart attack or stroke. Upon initial setup the system will be inserted into a human body and travel within its blood vessels. Based on sensors the system finds clogged areas and remove the blockage, without damaging the vessel's tissue using its cleaning system. The system independently and/or programmatically travels and searches for blockages within blood vessels using its own propulsion and navigation system. The system includes also a mechanism to remove and collect the removed plaque or any other blockage material.
