606127

A medical device and method for treatment in which the device has a portion for use within the body that exhibits enhanced properties such as radiopacity for viewing by x-ray fluoroscopy. The portion includes an extended metal outer member having, e. g. , a predetermined density and an exposed outer surface and a core, including a metal having, e. g. , a density greater than the outer member to enhance radiopacity, substantially enclosed by the outer member.

A medical retrieval device of an embodiment of the present disclosure includes a proximal handle, a sheath, and a retrieval assembly. The sheath extends from the handle and includes a lumen and a distal end opposite the handle. The retrieval assembly is moveable relative to the sheath to achieve a collapsed position of the retrieval assembly within the lumen and an expanded position of the retrieval assembly when extended outside the lumen. The retrieval assembly includes a plurality of legs. At least one of the legs includes a wire having an inner core at least partially surrounded by an outer layer.

A catheter comprises an elongated tube having an interior defined by a sidewall having openings. At least a portion of the catheter is spirally formed into a corkscrew pattern or has an inwardly spiraling portion with at least one opening coincident therewith. Additionally or alternatively, the catheter comprises a septum that divides the interior into at least first and second lumens. The first and second lumens may form a double helix in a portion of the catheter coincident with the plurality of openings or along the entire length of the catheter. Methods of manufacturing the catheters involve extruding the portion of the catheter having the openings, making this portion separately then attaching it to another catheter, or heating and deforming a portion of a catheter to form a tip portion. The catheter can be used for hemodialysis by drawing blood through one lumen and returning it through another.

Wires are used for conducting ultrasound energy. These wires achieve optimum properties by creating a multiple material coaxial construction. For example, in a particular embodiment it is desirable to have an elastic core (nitinol) for conducting axial vibrations (sonic or ultrasonic) and a thin stiff cladding (stainless steel) in order to minimize traverse vibrations which result in loss of energy.

The invention features a medical guidewire constructed for insertion into the body for providing access to a body passage. The medical guidewire has a main proximal portion in the form of an elongated tube extending the majority of the length of the guidewire, and a distal tubular portion integral with the main proximal portion. The distal portion includes a distal end and a flexible section having a slot cut in the wall of the distal tubular portion. The slot crosses the right sections of the distal tubular portion at an oblique angle and extends continuously about the distal tubular portion, in excess of at least one rotation about the distal tubular portion, to increase the flexibility of the distal tubular portion with respect to the main proximal portion.
