Abstract
A medical device having a support member disposed between an elongate shaft and a coil. The support member is adapted and configured to provide structural support to the coil so as to help maintain the position of the coil relative to the shaft.
Claims48
A medical device, comprising:
- an elongated shaft having an outer surface;
- a coil disposed about at least a section of the shaft, the coil having an inner surface, wherein at least a portion of the inner surface of the coil is radially spaced from at least a portion of the outer surface of the shaft such that a space is defined between the portion of the inner surface of the coil the portion of the outer surface of the shaft;
- a support member disposed within the space between the portion of the outer surface of the shaft and the portion of the inner surface of the coil.
A medical device, comprising:
- an elongated shaft having a portion with an outer diameter;
- a coil disposed about at least the portion of the shaft, the coil having at least a portion that has an inner diameter that is greater than the outer diameter of the portion of the shaft such that the portion of the coil is radially spaced from the portion of the shaft;
- a support member disposed between the portion of the shaft and the portion of the coil.
A medical device, comprising:
- an elongate shaft having a tapered distal region;
- a coil disposed about at least a portion of the tapered region;
- and
- a support member disposed between the shaft and the coil along at least a portion of the tapered region.

A guidewire, comprising:
- a core wire having a tapered distal region;
- a coil disposed around at least a portion of the distal region, the coil having a proximal end, a distal end, and a length;
- and
- a support member disposed between the core wire and the coil, the support member substantially spanning the length of the coil.
