Abstract
A method for accessing a target site in the body by transferring a guidewire from an initial insertion site on the body to a different insertion site on the body is provided. In one aspect, a method for transferring a medical device or component, such as a sensor lead, from an initial insertion site to another insertion site is also provided. A guidewire of sufficient length, pliancy and deformability to perform a transfer from one insertion site to another insertion site is provided. In one aspect, the guidewire comprises a removable core mandrel to increase rigidity, facilitate insertion and/or improve steerability. A kit or system, comprising introducers, guidewires and catheters for performing a guidewire or device transfer is also provided.
