Code:

// Controller: fetch breadcrumbs. Typically, this would return an array of objects or something
$breadcrumbs = $this->breadcrumb_m->get();
$this->load->view('some_view', array('breadcrumbs' => $breadcrumbs));

@JoostV: This breadcrumb_m , is this a model you have created your own, or a model based on a third-part library ?

I don't get it.. if it is a model you have created, how do you specify the name of the table and the fields you want to get in order to generate breadcrumbs??
