Abstract

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measurable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

Claims (52)

1. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media, the chamber comprising a detachable flange;

a container within the chamber and configured to hold the device, the container mechanically coupled to the detachable flange;

an air inlet gate fluidly upstream of the chamber and configured to be coupled to a gas source to flow gas into the chamber to fluidize the bath media;

a heating element between the air inlet gate and the chamber; and

a porous plate between the air inlet gate and the chamber.

2. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media, wherein the bath media comprises sand, the chamber comprising a detachable flange;

a container within the chamber and configured to hold the device, the container mechanically coupled to the detachable flange;

an air inlet gate fluidly upstream of the chamber and configured to be coupled to a gas source to flow gas into the chamber to fluidize the bath media;

a heating element between the air inlet gate and the chamber; and

a porous plate between the air inlet gate and the chamber.

3. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media, wherein the bath media comprises non-flammable particles, the chamber comprising a detachable flange;

a container within the chamber and configured to hold the device, the container mechanically coupled to the detachable flange;

an air inlet gate fluidly upstream of the chamber and configured to be coupled to a gas source to flow gas into the chamber to fluidize the bath media;

a heating element between the air inlet gate and the chamber; and

a porous plate between the air inlet gate and the chamber.

4. The system of claim 1 , wherein the porous plate is between the heating element and the air inlet gate.

5. The system of claim 1 , wherein the detachable flange comprises a conduit configured to allow passage of an arm mechanically coupling the container and the detachable flange.

6. The system of claim 5 , wherein adjustment of a length of the arm adjusts a height of the container in the chamber.

7. The system of claim 1 , wherein temperature in the chamber varies vertically with distance from the heating device.

8. The system of claim 1 , further comprising an air inflow regulator coupled to the air inlet gate.

9. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media, the chamber comprising a detachable flange;

a container within the chamber and configured to hold the device, the container mechanically coupled to the detachable flange;

an air inlet gate fluidly upstream of the chamber and configured to be coupled to a gas source to flow gas into the chamber to fluidize the bath media;

a heating element between the air inlet gate and the chamber;

a porous plate between the air inlet gate and the chamber; and

an air inflow regulator coupled to the air inlet gate, wherein a height of the air inflow regulator is adjustable to adjust the velocity of the gas into the chamber.

10. The system of claim 1 , wherein the gas source comprises nitrogen.

11. The system of claim 1 , wherein the gas source comprises air.

12. The system of claim 1 , wherein the gas source comprises hydrogen.

13. The system of claim 1 , wherein the gas source comprises carbon monoxide.

14. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media;

a container within the chamber and configured to hold the device;

an air inlet gate fluidly upstream of the chamber and configured to be coupled to a gas source to flow gas into the chamber to fluidize the bath media;

a heating element between the air inlet gate and the chamber; and

a temperature regulator configured to regulate temperature in the chamber by adjusting at least one of the air inlet gate and the heating element.

15. The system of claim 14 , further comprising thermal sensors electrically connected to the temperature regulator.

16. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media, gas flow into the chamber configured to fluidize the bath media, the chamber comprising a detachable flange comprising a handle;

a container within the chamber and configured to hold the device, a height of the container being adjustable; and

an arm mechanically coupling the chamber to the detachable flange.

17. A system for heat treating a device, the system comprising:

a chamber configured to contain bath media, gas flow into the chamber configured to fluidize the bath media, the chamber comprising a detachable flange comprising a handle;

a container within the chamber and configured to hold the device, a height of the container being adjustable; and

an arm mechanically coupling the chamber to the detachable flange, wherein the arm comprises at least one of a wire, a plurality of wires, and a hypotube.

18. The system of claim 16 , wherein adjustment of a length of the arm adjusts the height of the container in the chamber.

19. The system of claim 16 , wherein detachment of the detachable flange allows removal of the container from the chamber.

20. The system of claim 16 , further comprising air-sealant rivets on at least one of an inner surface of the detachable flange and an outer surface of the detachable flange.
