In the examples above you will need to have a type declared in the database, however you can create a pipelined function... something like this,
SQL> CREATE OR REPLACE Package My_Types Is
  2 
  3     Type enames_tab Is Table Of Varchar2(50);
  4 
  5  End My_Types;
  6  /
Package created
SQL> CREATE OR REPLACE Function lookup_ename Return my_types.enames_tab
  2     Pipelined Is
  3     v_row   my_types.enames_tab;
  4     cur     Sys_Refcursor;
  5     v_ename Varchar2(50);
  6  Begin
  7     v_row := my_types.enames_tab();
  8     Open cur For
  9        SELECT ename
10          FROM emp
11         WHERE ename IN ('SMITH', 'JAMES', 'WARD');
12     Loop
13        Fetch cur
14           INTO v_ename;
15        Exit When cur%Notfound;
16        v_row.Extend;
17        v_row(v_row.Count) := v_ename;
18        Pipe Row(v_row(v_row.Count));
19     End Loop;
20     Return;
21  End;
22  /
Function created
SQL> Set Serveroutput on;
SQL> Declare
  2     v_tab my_types.enames_tab;
  3  Begin
  4     SELECT ename Bulk Collect
  5       INTO v_tab
  6       FROM emp
  7      WHERE ename Member Of lookup_ename;
  8 
  9     For i IN v_tab.First .. v_tab.Last Loop
10        dbms_output.put_line(v_tab(I));
11     End Loop;
12  End;
13  /
SMITH
WARD
JAMES
