Abstract
Medical devices that are formed from a polymeric matrix including a first polymer and a functionalized polymer are provided. The medical devices may include a functionalized polymer such as maleic anhydride functionalized polymer. The burst strength and/or the hoop strength of the medical devices including the functionalized polymer may be greater than the burst strength and/or the hoop strength of control medical devices. However, the durometer of the medical devices may be substantially equal to the durometer of the control medical devices. Methods of manufacturing medical devices including a functionalized polymer are also provided.
Claims13
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.
