DIRECT INTEGRATION OF FEEDTHROUGH TO IMPLANTABLE MEDICAL DEVICE HOUSING BY SINTERING |
| 摘要 |
One aspect provides a method of attaching a feedthrough to a titanium housing of an implantable medical device. The method includes applying a sinter paste onto a surface of the housing about a perimeter of an opening through the housing, the sinter paste including a biocompatible bonding material, and placing an insulator of the feedthrough onto the sinter paste so as to cover the opening. The sinter paste is then heated to a temperature less than a beta-transus temperature the titanium of the housing and to a temperature less than a melting point of the biocompatible bonding material for a desired duration to form, from the sinter paste, a sinter joint which bonds the feedthrough to the housing and hermetically seals the opening. |

1. A method of attaching a feedthrough to a titanium housing of an implantable medical device, the method comprising:
applying a sinter paste onto a surface of the housing about a perimeter of an opening through the housing, the sinter paste including a biocompatible bonding material; placing an insulator of the feedthrough onto the sinter paste so as to cover the opening; and heating the sinter paste to a temperature less than a beta-transus temperature the titanium of the housing and to a temperature less than a melting point of the biocompatible bonding material for a desired duration to form, from the sinter paste, a sinter joint which bonds the feedthrough to the housing and hermetically seals the opening. |
