Medical device having magnetic properties
View Patent ↗A high-energy density magnetic particulate is mixed with a biocompatible material to form a composite. The composite may be formed into a sheet, which may be rolled into a tube and laser-cut to form at least one medical device, such as one piece of a multi-piece anastomosis device. The device includes a number of interconnected struts, which may be sized such that any portion of the member placed in the bloodstream is substantially non-thrombogenic. A magnetic field is induced in the composite.
1. A method of manufacturing a medical device, comprising:
providing a high-energy density magnetic material in particulate form;
combining said particulate with a biocompatible material to form a composite;
inducing a magnetic field in said composite;
forming said composite into a sheet; and
rolling said sheet into a tube.
2. The method of claim 1 , wherein said providing includes crushing a high-energy density magnetic material into a particulate.
3. The method of claim 1 , wherein said high-energy density magnetic material is samarium cobalt.
4. The method of claim 1 , wherein said high-energy density magnetic material is neodymium iron boron.
5. The method of claim 1 , wherein said particulate includes plurality of constituent particles, further comprising coating said constituent particles of said particulate with gold.
6. The method of claim 1 , wherein said combining comprises:
mixing said particulate with biocompatible material in a substantially liquid state to form a mixture; and
transitioning said mixture to a substantially solid state.
7. The method of claim 6 , wherein said transitioning comprises cooling said mixture.
8. The method of claim 6 , wherein said transitioning comprises drying said mixture.
9. The method of claim 6 , wherein said transitioning comprises curing said mixture.
10. The method of claim 1 , wherein said inducing comprises placing said composite in a magnetic field.
11. The method of claim 1 , further comprising cutting said tube.
12. The method of claim 11 , wherein said cutting is performed with a laser.
13. The method of claim 11 , wherein said inducing is performed after said rolling.
14. The method of claim 11 , wherein said inducing is performed after said cutting.
