Funeral expenses are a personal expense that are never tax deductible no matter who they are for.
You could deduct medical expenses paid in 2016 on your tax return if your partner was your tax dependent for 2016. Your partner can be your tax dependent for 2016 if, during the time they were alive in 2016, your partner lived as a member of your household exclusively, and your partner did not earn more than $4050 for 2016.
