Apparatus and method for maintaining a tracheal stoma
First Claim
1. An apparatus for maintaining a tracheal stoma in a patient, the stoma extending through a wall defined by the anterior tracheal wall and the patient'"'"'s neck, the apparatus comprising:
- a) a cannula having first and second opposite end portions with first and second coterminous openings therein, the cannula being insertable into the stoma such that the first end portion protrudes into the trachea and the second end portion protrudes from the neck;
b) retaining means for retaining the cannula in the stoma, the retaining means being external to the first and second coterminous openings to maintain the first and second coterminous openings unobstructed, the retaining means including an expandable and collapsible member secured the first end portion and capable of expandable to interfere with the anterior tracheal wall to prevent the first end portion from being withdrawn from the stoma while presenting a negligible effect to airflow in the trachea and collapsible to prevent interference of the member with the anterior tracheal wall to permit the first end portion to be withdrawn from the stoma; and
c) squeezing means on the cannula for squeezing the wall, defined by the anterior tracheal wall and the neck, between the expandable member and the second end portion to hold the cannula securely in the stoma.

Abstract
A releasably anchorable bushing conduit apparatus for providing access through a wall having a generally accessible side and a generally inaccessible side and an opening extending through the wall from the generally accessible side to the generally inaccessible side comprises a bushing conduit having first and second opposite end portions with first and second coterminous openings therein. The bushing conduit is insertable into the opening such that the first end portion protrudes from the wall on the inaccessible side and the second end portion protrudes from the wall on the accessible side. A retaining device external to the first and second coterminous openings retains the bushing conduit in place, yet presents no obstruction to the first and second coterminous openings. The retaining device includes an expandable and collapsible member secured to the first end portion and capable of expanding to interfere with the inaccessible side to prevent the first end portion from being withdrawn from the opening from the accessible side. The expandable and collapsible member is also capable of being collapsed to prevent interference of the member with the inaccessible side to permit the first end portion to be withdrawn from the opening. A device is provided on the bushing conduit for squeezing the wall between the expandable member and the second end portion to hold the bushing conduit securely in the wall opening.

14. A method of maintaining a tracheal stoma in a patient, the stoma extending through a wall defined by the anterior tracheal wall and the patient'"'"'s neck, the method comprising the steps of:
-
a) inserting a first end portion of a cannula into a tracheal stoma such that the first end portion protrudes into the trachea and such that a second end portion of the conduit protrudes from the neck of the patient; b) expanding an expandable and collapsible member secured to the first end portion, while maintaining first and second coterminous openings of the cannula unobstructed such that said expandable member interferes with the anterior tracheal wall to prevent the first end portion from being withdrawn from the tracheal stoma from the neck, while presenting a negligible effect to airflow in the trachea; and c) squeezing the wall defined by the anterior tracheal wall and the neck, between the expandable member and the second end portion to hold the cannula securely in the tracheal stoma. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
