1. An introducer element, comprising:
- a body having a first and second lumen, each having a distal end and a proximal end, wherein the first and second lumen merge at their distal ends to provide a combined lumen having a proximal end and a distal end;
a quantity of tearable, selectively removable peel-away tubing having a proximal end and a distal end, wherein a slit is defined at a point between the proximal end and the distal end of the quantity of peel away tubing, the quantity of peel-away tubing being disposed within the second lumen and the combined lumen; and
a tube disposed within the first lumen, passing through the slit defined by the quantity of peel-away tubing and into the combined lumen.

Abstract
The present invention provides an introducer element for facilitating the insertion of a medical instrument into a body. The introducer element includes first, second, third and fourth housing areas. The first area contains a first lumen and the second area contains a second lumen. A quantity of peel-away tubing is partially disposed within the second lumen. The first and second lumen are separated from each other in the first and second housing areas, but are merged into one lumen in either the third or fourth housing area by a guide/splitting tube.

13. A method for introducing a medical instrument into a body, comprising the steps of:
-
providing an introducer element, comprising;
a body having a first and second lumen, each having a distal end and a proximal end, wherein the first and second lumen merge at their distal ends to provide a combined lumen having a proximal end and a distal end;
a quantity of tearable, peel-away tubing having a proximal end and a distal end, wherein a slit is defined at a point between the proximal end and the distal end of the quantity of peel away tubing, the quantity of peel-away tubing being disposed within the second lumen and the combined lumen;
a tube disposed within the first lumen, passing through the slit defined by the quantity of peel-away tubing and into the combined lumen; and
a stylet disposed within the introducer element such that at least a portion of the stylet distally protrudes from the combined lumen of the introducer element;
providing an entry facilitation element having at least one lumen defined therethrough;
inserting the entry facilitation element into the body to a predetermined depth within the body such that at least a portion of the entry facilitation element protrudes from the body;
properly placing the introducer element in the entry facilitation element;
removing the quantity of peel-away tubing from the introducer element. - View Dependent Claims (14)
