Alternative designs, materials and manufacturing methods for guidewires. Some embodiments pertain to a composite guidewire having proximal and distal section, and a connector adapted and configured for permanently joining the proximal section to the distal section. In some embodiments, at least one of the sections is made of a linear-elastic nickel-titanium alloy. Several alternative guidewire tip designs including coiled safety/shaping structures are also disclosed.

Composite guidewire

Alternative designs, materials and manufacturing methods for medical devices. Some embodiments disclosed deal with attachment of an elongated structure, such as a wire or ribbon, or a tubular member, such as a coil, to an elongated member in an elongated device. For example, an elongated core member having defining an outer surface, and an elongated structure including a first portion and a second expanded portion along the length thereof can be provided. An attachment member, such as a centering ring, or the like, is disposed about a portion of the elongated core member and a part of the first portion of the elongated structure. The attachment member defines a lumen and having an inner surface. Part of the first portion of the elongated structure is disposed between the inner surface of the attachment member and the outer surface of the elongated core member. A part of the second portion of the elongated structure is in mechanical engagement with the inner surface of the attachment member and the outer surface the elongated core member to provide a mechanical coupling of the elongated structure between the attachment member and the elongated core member. Some embodiments provide a method of making such a construction, wherein the elongated structure can be moved relative to the attachment member such that the second portion of the elongated structure engages the inner surface of the attachment member and the outer surface the elongated core member to mechanically couple the elongated structure to the elongated core member.

Elongated medical device for intracorporal use

A medical device, such as a medical guidewire, having a portion including an inner zone of material and an outer peripheral zone of material surrounding the inner zone of material. The inner zone of material has a first coefficient of thermal expansion and the outer peripheral zone of material has a second coefficient of thermal expansion less than the first coefficient of thermal expansion, wherein at an operating temperature the outer peripheral zone of material opposes expansion of the inner zone of material such that the outer peripheral zone of material exerts a compressive stress on the inner zone of material.

Guidewires with improved fatigue life and methods of making the same

Elongate medical devices such as guidewires can be formed from a core wire and a preformed distal cap that is configured to fit over a distal end of the core wire. The distal cap can be attached using a variety of techniques. In particular, the distal cap can be attached to the core wire using laser welding.

Method of making elongated medical devices

Medical devices and methods of manufacturing medical devices. The medical devices include an elongate member having a proximal portion and a distal portion and a connector assembly disposed adjacent the elongated member to connect the proximal and distal portions, the connector assembly including a radiopaque marker.

Composite medical device with markers

The invention provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes an elongated core member including an outer surface, an intermediate member disposed about at least a portion of the outer surface of the core member, and a coil disposed about at least a portion of the intermediate member in the distal region. At least a portion of an outer surface of the coil can include an undulating surface in a portion of the distal region.

Elongate medical device with distal cap

Alternative designs and materials suitable for connecting different guidewire sections together. More particularly, connecting two portions of a guidewire having different material compositions with a connector having a third composition which is readily weldable to each of the dissimilar portions of the guidewire. A transition area may be designed to provide a region of desired flexibility characteristics.

Guidewire with stiffness blending connection

Devices and methods for coupling guidewire system components are disclosed. A guidewire system includes a first wire having a first end and a second wire having a second end which may be selectively coupled to the first end of the first wire. Such guidewire systems are useful as guidewire extension systems.
