1. A trans-luminal, guidewire-advanced, rapid-exchange surgical delivery device having a proximal end, a primary shaft and a distal zone to be advanced over a guidewire along a bodily lumen to a site of surgery, the device comprising:

  • i. a guidewire tube defining a guidewire lumen, said guidewire tube lying within the distal zone with the guidewire lumen to one side of the primary shaft, the guidewire lumen having a length that longitudinally overlaps a length of the primary shaft and having a proximal end opening which lies to one side of the primary shaft; and

    ii. a sleeve comprising a unitary outer wall extending over an entire length of the sleeve, the sleeve defining only a single lumen, the sleeve lumen configured to receive a surgical element distal of the guidewire tube, a proximal end of the sleeve including a radially inwardly tapering portion over a proximal end opening of the guidewire tube, said inwardly tapering portion defining a proximal guidewire lumen exit port, and a tubular constant diameter nose portion surrounding the primary shaft proximal of the radially inwardly tapering portion, the nose portion defining a proximal-most end of the sleeve.
