1. A method of increasing the burst strength of an extruded medical device, the method comprising:
obtaining a polymeric matrix comprising:
a first polymer, wherein the first polymer is selected from at least one of polyurethane, polyether block amide, or nylon; and
a maleic anhydride functionalized polymer, wherein the maleic anhydride functionalized polymer is maleic anhydride polyporpylene (MAPP), wherein the weight-to-weight ration od the maleic anhydride functionalized polymer in the polymeric matrix is between 0.5 wt. % and 8 wt. %; and
extruding the polymeric matrix to form a medical device comprising:
an elongate body; and
a lumen extending through a portion of the elongate body.
