In an embodiment, a catheter apparatus includes a catheter and a substantially soluble insertion point extending beyond a distal end of the catheter. The substantially soluble insertion point may be connected to a substantially soluble needle shaft or to a non-soluble needle shaft. The catheter apparatus includes a partial retraction mechanism, in an embodiment, which enables the substantially soluble insertion point to be retracted to a position within the catheter. In other embodiments, the substantially soluble insertion point is fully retractable (i.e., removable) or is non-retractable. |
