Medical devices
View Patent ↗Medical devices and related methods are disclosed.
1. A finished medical device prepared for use, comprising:
a tubular member comprising magnetically alignable nanotubes, wherein a first portion of the tubular member has a first flexibility and includes a first plurality of magnetically alignable nanotubes having a first magnetic permeability, wherein a second portion of the tubular member has a second flexibility different from the first flexibility and includes a second plurality of magnetically alignable nanotubes having a second magnetic permeability that is different from the first magnetic permeability, and wherein the tubular member consists of one layer.
2. The medical device of claim 1 wherein the medical device has a proximal end, a distal end and an elongate axis extending therebetween and wherein the first portion extends along a first portion of the elongate axis and wherein the second portion extends along a second portion of the elongate axis wherein the first portion is different from the second portion.
3. A finished medical device prepared for use, comprising:
a first portion comprising a first plurality of magnetically alignable particles that are collectively oriented in a first direction; and
a second portion comprising a second plurality of magnetically alignable particles that are substantially randomly oriented,
wherein the medical device has a proximal end, a distal end and an elongate axis extending therebetween and wherein the first portion extends along a first portion of the elongate axis and wherein the second portion extends along a second portion of the elongate axis wherein the first portion is different from the second portion.
4. A finished medical device prepared for use, comprising:
an elongate shaft having a first portion, a second portion, and a third portion;
wherein the first portion includes a first plurality of magnetically alignable fibers that are all oriented substantially parallel to the longitudinal axis of the shaft;
wherein the second portion includes a second plurality of magnetically alignable fibers that are all oriented in the substantially the same direction and that are all oriented in a direction different from the first plurality of magnetically alignable fibers; and
wherein the third portion includes a third plurality of magnetically alignable fibers that are substantially randomly oriented.
