Abstract
Medical devices and methods for making and using the same. An example medical device includes a slotted tubular member and a coating disposed over the tubular member. The coating may define one or more coating gaps therein.
Claims19
A method for coating at least a portion of a medical device, the method comprising:
- providing an elongate medical device, the medical device including an elongate core member having a proximal end region and a distal end region and a tubular member disposed over the distal end region, the tubular member having an outer surface and a plurality of slots formed along the outer surface;
- masking a portion of the tubular member adjacent at least one of the slots with a masking agent, wherein the masking agent is a structural barrier positioned within the tubular member and a portion of the masking agent projects through one or more of the plurality of slots, is spaced apart from sidewalls of the slots, and extends outward beyond an outer surface of the tubular member;
- coating the tubular member with a coating material;
- and
- removing the masking agent, wherein a coating gap is defined in the coating material at a location corresponding to the position of the masking agent.

A method for manufacturing a medical device, the method comprising:
- providing an elongate core member having a proximal end region and a distal end region and a tubular member disposed over the distal end region, the tubular member having a plurality of slots formed therein;
- wherein the tubular member has an outer surface and an interior lumen;
- wherein at least some of the slots have a longitudinal length and a width that is greater than the longitudinal length;
- providing a masking member, wherein the masking member is a structural barrier positioned within the tubular member and a portion of the masking member projects through one or more of the plurality of slots and is spaced apart from sidewalls of the slots and extends outward beyond an outer surface of the tubular member;
- wherein the masking member includes a first portion configured to extend within the interior lumen of the tubular member and a second portion configured to extend through one or more of the slots;
- arranging the masking member so that the first portion is disposed within the interior lumen of the tubular member and so that the second portion extends through at least one of the slots;
- coating the outer surface of the tubular member with a coating material;
- removing the masking member from the tubular member;
- and
- wherein removing the masking member defines a coating gap in the coating material.
