    $CI =  get_instance();
    $categories = $CI->Product_model->get_categories();
    return $categories;
}

function in model is

public function get_categories(){

    $this->db->select('*');
    $this->db->from('categories');
    $query = $this->db->get();
    return $query->result();
}

code in the view is

<?php foreach(get_categories_h() as $category) : ?>
                            <li class="list-group-item"><a href="#"><?php echo $category->name; ?></a></li>
                            <?php endforeach; ?>

You will need to load the model in your helper for it to be accessible. Something like:

<?php

function get_categories_h(){
    $CI =  get_instance();
    $CI->load->model('Product_model');
    $categories = $CI->Product_model->get_categories();
    return $categories;
}

You can read more about how to load it at: http://www.codeigniter.com/userguide2/general/models.html#loading

or

Depending on what CI version you are using.
