"I have a lead wire containing a polyimide jacket. I need to bond the polyimide jacket to a titanium housing. The bond needs to provide a strain relief, and more importantly a fluid-tight seal. The adhesive needs to be rated for long-term implant use. Can you make an adhesive recommendation for this application?"

There are relatively few long-term implant adhesives on the market. NuSil Technology offers MED-2000, which is a one-component silicone RTV adhesive, and MED1-4213 is a two-component addition-cure silicone adhesive. Applied Silicone also offers long-term implant adhesives, such as P/N 40064. Since both companies offer other alternatives besides these, I would recommend contacting their respective sales/technical departments to discuss further.
