Abstract
Medical devices and related methods are disclosed.
Claims32
A method of manufacturing a medical device or a medical device component, the method comprising:
- mixing a first polymer in a liquid state with a magnetically alignable material to form a liquid mixture;
- extruding the liquid mixture to form an elongate element having a longitudinal axis and at least a first layer;
- applying a magnetic field to align the magnetically alignable material as the first polymer is extruded, wherein applying the magnetic field includes orienting the magnetically alignable material in a first portion of the elongate element to have a first orientation, and orienting the magnetically alignable material in a second portion of the elongate element to have a second orientation that is different from the first orientation, wherein the first and second portions of the elongate element are longitudinally spaced apart along the first layer;
- and
- solidifying the first polymer to form the medical device or the medical device component.

A method of making a medical device or a medical device component, the method comprising:
- mixing a first magnetically alignable material with a first polymer to form a first composition, the first composition being in a liquid state;
- aligning at least a first portion of the first magnetically alignable material in the liquid first composition in a first direction;
- aligning a second portion of the first magnetically alignable material in the liquid first composition in a second direction different from the first direction, wherein the concentration and/or alignment of magnetically alignable material differs in the first and second portions;
- and
- solidifying the first composition to form the medical device or the medical device component;
- wherein the medical device or the medical device component has a longitudinal axis and at least a first layer, wherein the first and second portions are longitudinally spaced apart along the first layer, wherein the first direction is parallel to the longitudinal axis.
