摘要： An intravascular guide wire having two core materials joined together without the use of a connector tube or sleeve, the core materials being stainless steel and psuedoelastic metal alloy, nitinol. The core materials are joined to each other through an intermediate transition piece made essentially of nickel, which is welded on either side to the two core materials. In a multi-segment intravascular guide wire, discrete, high modulus and medium modulus core portions of different materials are welded to a shapeable, low modulus distal core portion made of a third material having a flattened, shapeable section at a most distal end that is not welded to but made from the distal core portion, so the flattened, shapeable section can be deformed to create a steerable tip. Processes such as simultaneous resistance and friction welding can be used to join the core portions.

摘要： A shaped guidewire for use in medical applications is disclosed. The guidewire is shaped so as to prevent inadvertent advancement of the guidewire into the corpus of a patient during use. In one embodiment, the guidewire includes an elongate body that defines proximal and distal ends. The guidewire body further defines a shaped portion that is positioned intermediate the proximal and distal ends. The shaped portion of the guidewire is at least partially composed of a shape memory material, such as nitinol, and is deflected from a longitudinal axis defined by an undeflected portion of the guidewire body. The shaped portion is disposed in one embodiment at the proximal end of the guidewire. In another embodiment, a proximal portion of the nitinol guidewire can be treated to impart malleability and enable deflection by a clinician. Methods for forming the shaped or malleable guidewire to include a deflected portion are disclosed.

摘要： An intracorporeal device includes an elongate tubular member. The tubular member can comprise one or more materials that have superelastic and/or shape memory characteristics. The tubular member can comprise one or more deformable zones and one or more elastic zones. The deformable zone(s) can comprise material(s) that are less elastic than the material in the elastic zone(s). The deformable and elastic zones can contain different materials or they can contain the same or similar materials that have been treated in order to change the elasticity or type of elasticity of one of the zones relative to the other zones, creating different elasticity between the elastic and the deformable zones. The intracorporeal device can be, for example, a guidewire, a catheter or any other intracorporeal device that can include an elongate tubular member.

摘要： The present document describes a pressure guidewire comprising: a shaft tube with a proximal section; a middle section extending from the proximal section of the shaft tube, the middle section having greater flexibility than the proximal section; an inner hypotube installed substantially within the middle section for optimal mechanical properties; a pressure sensor with a communication means routed through the middle section and the proximal section; and a sensor housing for receiving the pressure sensor. There are also described methods for joining the inner hypotube to the shaft tube.
