Using transaction in cursor with try..catch - sql-server

Question

I have a large stored procedure which utilises a cursor. I want to put each instance of the cursor processing into a transaction, with a try-catch on the one insert, which on failure would terminate that transaction, back any inserts it did and then move to the next cursor instance. However, I am struggling with structuring this.
An example of what it looks like in brief is below. Basically I am trying to structure the try-catch for the patient insert to rollback the transaction and go onto the next cursor value when the patient insert fails.
Thanks
