A shrink tubing jacket construction enables blade-free or enhanced removal of shrink tubing from an underlying substrate, such as a catheter construction. The shrink tubing jacket construction comprises a length of shrink tubing and one or more tear members located within the wall of the shrink tubing. The wall of the shrink tubing has a certain first material strength and the tear member has a certain second material strength, such that when the tear member is in tension, the second material strength functions to slice through the wall of the shrink tubing for enabling blade-free removal of the same. Paired tear members may be diametrically opposed such that when simultaneously tensioned in a diametrical direction, the net stress on the underlying substrate is minimized during the slicing action.
