Anchored guidewire
First Claim
1. A method of using a guide wire in a bodily cavity, comprising the steps of:
- inserting into a bodily cavity an elongated guide wire havinga balloon at a distal end of the guide wire;
a fiber mesh disposed over the balloon and affixed thereto; and
a lumen in fluid communication with the balloon;
advancing the distal end of the guide wire through the bodily cavity until the balloon reaches an anchoring position;
supplying fluid though the lumen to the balloon until the balloon is inflated such that the balloon with the fiber mesh exerts pressure on the wall of the bodily cavity to retain the balloon in the anchoring position;
advancing a medical device over the elongated guide wire through the bodily cavity while the balloon is inflated until the medical device reaches a desired position;
deflating the balloon; and
withdrawing the guide wire through the medical device and out of the bodily cavity.

Abstract
An anchored guide wire is described including at least one expansion apparatus having an outer surface for contacting surrounding tissue, an elongated guide wire with at least one lumen for supplying fluid to the expansion apparatus, and a pump that supplies fluid to the lumen to inflate the expansion apparatus, wherein the outer surface of the expansion apparatus has a textured surface for preventing slippage on surrounding tissue. A method of securing a guide wire in a bodily cavity is also described including inserting an elongated guide wire with an expansion apparatus having a textured outer surface and a lumen for supplying fluid to the expansion apparatus, into the bodily cavity, supplying fluid to the lumen with a pump until the expansion apparatus is inflated, moving a medical device along the elongated guide wire, deflating the expansion apparatus, and withdrawing the guide wire from the bodily cavity.
