Broduer spent all 21 prior NHL seasons with the New Jersey Devils, backstopping the team to three Stanley Cup titles, but was a free agent this year.
Even in the twilight of his career, the Canadian netminder who won Olympic gold in 2002 and 2010 has something to offer the Blues, who are among six NHL teams with a season-best 34 points after two months.
Brodeur led the NHL in wins in nine different seasons and is the league's all-time wins leader among goalies with 688.
He won the Vezina Trophy as the NHL's best goaltender in a season in 2003, 2004, 2007 and 2008 and helped the Devils take the Stanley Cup in 1995, 2000 and 2003.
Brodeur has a career record with the Devils of 688-394 with 176 drawn and a 2.24 goals against average, a 91.2 save percentage and 124 shutouts.
His NHL regular season records includes wins, shutouts, games played (1,259) and minutes played (74,083). His 24 playoff shuts and 204 starts are records and his 113 wins ranks second in league playoff history.
The Montreal native played in 39 games last season, going 19-14-6 with a 2.51 goals against average and three shutouts. AFP
