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.

The invention relates generally to medical devices. More specifically, the invention relates to intracorporal medical device, such as a guidewire, catheter, or the like, including structure for crossing an occlusion in a vessel or a patient.
The use of intravascular medical devices has become an effective method for treating many types of vascular disease. In general, one or more suitable intravascular devices are inserted into the vascular system of the patient and navigated through the vasculature to a desired target site. Using this method, virtually any target site in the patient's vascular system may be accessed, including the coronary, cerebral, and peripheral vasculature. Examples of therapeutic purposes for intravascular devices include percutaneous transluminal angioplasty (PTA) and percutaneous transluminal coronary angioplasty (PTCA).
When in use, intravascular devices, such as a guidewire, may enter the patient's vasculature at a convenient location and then can be urged to a target region in the anatomy. The path taken within the anatomy of a patient may be very tortuous, and as such, it may be desirable to combine a number of performance features in the intravascular device. For example, it is sometimes desirable that the device have a relatively high level of pushability and torqueability, particularly near its proximal end. It is also sometimes desirable that a device be relatively flexible, particularly near its distal end, for example, to aid in steering.
The invention may be more completely understood in consideration of the following detailed description of various embodiments of the invention in connection with the accompanying drawings, in which:
FIG. 1 is a partial perspective view of one embodiment of a guidewire;
FIG. 2 is a partial cross-sectional view of the guidewire of FIG. 1;
While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
For the following defined terms, these definitions shall be applied, unless a different definition is given in the claims or elsewhere in this specification.
All numeric values are herein assumed to be modified by the term “about,” whether or not explicitly indicated. The term “about” generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (i.e., having the same function or result). In many instances, the terms “about” may include numbers that are rounded to the nearest significant figure.
