and the proximal insertion end portion including a tip region, wherein at least a section of the tip region comprises an open-cell porous structure. ### Claim 2 (depends on 1) The urinary catheter of claim 1, wherein the open-cell porous structure defines a terminal proximal tip of the catheter shaft. ### Claim 3 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip defined by the open-cell porous structure includes an central opening that is coaxial and in fluid communication with a drainage lumen of the catheter shaft. ### Claim 4 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip defined by the open-cell porous structure has a generally torus or toroidal shape. ### Claim 5 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip defined by the open-cell porous structure has a cross-sectional profile in a plane parallel to a longitudinal axis of the catheter shaft, wherein the cross-sectional profile has a polygonal shape. ### Claim 6 (depends on 5) The urinary catheter of claim 5, wherein the polygonal shape of the cross-sectional profile is trapezoidal. ### Claim 7 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip includes a base and a top, wherein a widest dimension of the base is wider than a widest dimension of the top. ### Claim 8 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip includes a base and a top, wherein a widest dimension of the top is wider than a widest dimension of the base. ### Claim 9 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip defined by the open-cell porous structure has a cross-sectional profile in a plane parallel to a longitudinal axis of the catheter shaft, wherein cross-sectional profile has a stilted arch shape. ### Claim 10 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip of the catheter shaft has a cross-sectional dimension in a plane perpendicular to the longitudinal axis of the catheter shaft that is larger than a diameter of a remaining portion of the catheter shaft. ### Claim 11 (depends on 2) The urinary catheter of claim 2, wherein the terminal proximal tip of the catheter shaft has a portion that extends in a radial direction beyond an outer surface of an immediately adjacent segment of the catheter shaft. ### Claim 12 (depends on 1) The urinary catheter of claim 1, wherein the catheter shaft includes a drainage lumen and the section of the tip region comprising the open-cell porous structure is in communication with the drainage lumen. ### Claim 13 (depends on 12) The urinary catheter of claim 12, wherein the proximal tip region includes a terminal proximal tip. ### Claim 14 (depends on 13) The urinary catheter of claim 13, wherein the terminal proximal tip is closed. ### Claim 15 (depends on 13) The urinary catheter of claim 13, wherein the open-cell porous structure extends distally from the terminal proximal tip. ### Claim 16 (depends on 13) The urinary catheter of claim 13, wherein the open-cell porous structure is spaced about 1 mm to about 40 mm from the terminal proximal tip. ### Claim 17 (depends on 12) The urinary catheter of claim 12, wherein the open-cell porous structure has a length perpendicular to a longitudinal axis of the catheter shaft, wherein the length is between about 3 mm and about 5 mm. ### Claim 18 (depends on 12) The urinary catheter of claim 12, wherein in the open-cell porous structure extends circumferentially around the catheter shaft. ### Claim 19 (depends on 12) The urinary catheter of claim 12, wherein the proximal insertion end portion does not include discrete drainage eyes that extend through a wall of the catheter shaft. ### Claim 20 (depends on 1) The urinary catheter of claim 1, wherein the open-cell porous structure comprises a foamed polymer. ### Claim 21 (depends on 1) The urinary catheter of claim 1, wherein the open-cell porous structure comprises a sintered polymer particles. ### Claim 22 (depends on 1) The urinary catheter of claim 1, wherein the open-cell porous structure comprising cells having a size between 10 um and 100 um. ### Claim 23 (canceled) ### Claim 24 (canceled)
