1. A method of advancing a surgical device having a filter into a mammalian body, comprising:

  • a) inserting a guidewire into the mammalian body;

    b) mounting a basket device having a proximal portion and a distal portion to the guidewire such that a portion of the basket device extends non-concentrically alongside the guidewire and the proximal portion of the basket device coupled to the guidewire;

    wherein the basket device includes a filter basket having a first shaft element having a distal portion coupled to the proximal portion of the filter basket, a second shaft element having a distal portion coupled to the distal portion of the filter basket, and a guidewire mounting means;

    wherein the guidewire mounting means is a coil;

    wherein the step of mounting a basket device to the guidewire includes mounting the coil onto a mid-portion of the guidewire;

    wherein the step of mounting a basket onto the guidewire further includes wrapping the coil onto the guidewire at a location near where the guidewire enters the mammalian body;

    c) slidably advancing the basket device relative to the guidewire until the filter is at a desired location within the mammalian body; and

    d) expanding the basket device.
