问题
I want to create a procedure to clone SQL Server database using T-SQL . I'm using cursors to clone objects (tables, procedures, functions ,...).
How can i get user-defined-table-type definition from System Catalog Views ?

Here is your answer. Below query gives the result of all types as a text. You can proceed this result using loop or whatever and migrate to another database.
SELECT '
IF EXISTS (SELECT * FROM sys.types st JOIN sys.schemas ss ON st.schema_id = ss.schema_id WHERE st.name = N''' + st.[name] + ''' AND ss.name = N''' + ss.[name] + ''')
DROP TYPE ' + QUOTENAME(ss.name, '[') + '.' + QUOTENAME(st.name, '[') + '
GO
CREATE TYPE ' + QUOTENAME(ss.name, '[') + '.' + QUOTENAME(st.name, '[') + ' FROM ' +
QUOTENAME(bs.[name], '[') +
CASE bs.[name]
WHEN 'char' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length) + ')' END)
WHEN 'nchar' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length/2) + ')' END)
WHEN 'varchar' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length) + ')' END)
WHEN 'nvarchar' THEN (CASE ISNULL(st.max_length, 0) WHEN 0 THEN '' WHEN -1 THEN '(MAX)' ELSE '(' + convert(varchar(10), st.max_length/2) + ')' END)
WHEN 'numeric' THEN (CASE ISNULL(st.[precision], 0) WHEN 0 THEN '' ELSE '(' + convert(varchar(10), st.[precision]) + ', ' + convert(varchar(10), st.[scale]) + ')' END)
WHEN 'decimal' THEN (CASE ISNULL(st.[precision], 0) WHEN 0 THEN '' ELSE '(' + convert(varchar(10), st.[precision]) + ', ' + convert(varchar(10), st.[scale]) + ')' END)
WHEN 'varbinary' THEN (CASE st.max_length WHEN -1 THEN '(max)' ELSE '(' + convert(varchar(10), st.max_length) + ')' END)
ELSE ''
END +
'
GO
'
FROM sys.types st
INNER JOIN sys.schemas ss ON st.[schema_id] = ss.[schema_id]
INNER JOIN sys.types bs ON bs.[user_type_id] = st.[user_type_id]
WHERE st.[is_user_defined] = 1
ORDER BY st.[name], ss.[name]

Find the table you'd like to copy in the Object Explorer... Right click the table name and choose... Script Table as > CREATE To > New Query Editor Window.
