Abstract
Provided is foley catheter and a composition for producing a foley catheter which is inserted in vivo and a method for producing the same, which the composition consists of the materials which carbon nanotube polymer (CNT Polymer) bonded a carbon nanotube and zinc oxide (ZnO) is combined with a silicon, wherein from 1.0 to 2.2 parts by weight of the said carbon nanotube polymer are combined with 100 parts by weight of silicon.
Claims18
A foley catheter comprising:
- a catheter body made of a first material comprising a first carbon nanotube polymer mixed with silicon;
- wherein the catheter body is formed as a single layer with at least one fluid passage,
- a foley balloon connected to the catheter body and configured to be inflated by a fluid introduced from outside, wherein the foley balloon is made of a second material comprising a second carbon nanotube polymer mixed with silicon, and
- an insulating layer disposed solely between the catheter body and the foley balloon, the insulating layer configured to prevent electric current from flowing from the foley balloon to the catheter body,
- wherein the first and second carbon nanotube polymers are polymerized with carbon nanotube and zinc oxide (ZnO), and
- wherein the second material has a higher mixing ratio of the second carbon nanotube polymer than the first carbon nanotube polymer, and there is an electrical potential difference between the foley balloon and the catheter body.
