Definitions

  • the present invention relates to medical care for the larynx, trachea or bronchi to relieve a stenosis.
  • the invention relates to a device for performing dilation of the larynx, trachea or bronchi.
  • Subglottic stenosis is a congenital or acquired narrowing of the subglottic airway.
  • subglottic stenosis was rare, and most cases occurred in adults.
  • the incidence of acquired subglottic stenosis began to dramatically increase in the neonatal population, most likely the result of increased survival of low-birth-weight infants and the increased use of intubation in this population.
  • Airway balloon dilation has been shown to be a safe and effective palliative procedure for treatment of mild congenital and acquired stenosis of the trachea and bronchi.
  • Dilation of luminal human anatomy to treat stenoses can be dated back to the 16 th Century with esophageal “bougie” dilation.
  • Specific medical applications of luminal balloon dilation range from alimentary canal and airway dilation to dilation of the vasculature.
  • Airway dilation dates back over 100 years ago with the invention and subsequent use of the first beveled rigid bronchoscopes for stricture management.
  • Airway balloon dilation can be used to quickly re-establish tracheal or bronchial luminal patency to restore airflow in a way that doesn't cause excessive trauma to the patient.
  • Literature has reported the use of balloon dilation for the treatment of benign strictures of the airway.
  • Fibrotic strictures such as those secondary to tuberculosis, long-term endotracheal or tracheostomy tube placement, berylliosis, Wegener's granulomatosis, or sarcoidosis have been shown to be treatable with airway balloon dilation therapy with general success. Additionally, balloon dilation has been useful in treating strictures secondary to major surgical interventions such as lung transplantation, sleeve resection, bronchial re-implantation, and lobectomy. For the purpose of treating strictures secondary to malignant obstruction, dilation therapy can be used alone or in combination with other techniques such as surgical resection, cryotherapy, laser therapy, and stent placement, depending on the desired outcome for the patient.
  • Treatment with airway dilation can involve the clinician inserting increasingly larger tubes into the airway (e.g. endotracheal tubes or cat-tail (bougie) dilators), which creates significant shear forces on the airway mucosa.
  • endotracheal tubes or cat-tail (bougie) dilators e.g. endotracheal tubes or cat-tail (bougie) dilators
  • a procedure sometimes induces unwanted trauma to the airway in the form of deep lacerations and hemoptysis.
  • current dilation practices do not permit dilation of a tracheal stenosis that is distal to a narrowing of the proximal airway (i.e. a mild subglottic stenosis).
  • angioplasty balloons Current airway balloon dilation procedures are typically carried out using angioplasty balloons; however, several limitations to the use of angioplasty balloons become evident when used on the airway. For example, it may be difficult to adequately ventilate the patient during the dilation period, since the typical angioplasty balloon does not include a connection to an oxygen source. Further, the shape of the angioplasty balloon may predispose the balloon to slide out of place during dilation, or the balloon may be limited to the amount of pressure that can be applied before the balloon bursts. Also, the typical angioplasty balloon can usually stretch the airway lumen but not permanently dilate it. Other factors associated with failure of airway balloon dilation include previous attempts at endoscopic repair, circumferential scarring, and loss of cartilaginous support.
  • a balloon dilator for the airway of a patient that is able to allow ventilation of the patient during balloon inflation. It would also be helpful to provide an airway balloon dilator that can provide increased inflation pressures during balloon dilation of the airway without balloon rupture. Further, it would be beneficial to provide a balloon that will not slip out of place in the patient's airway during balloon inflation. Finally, it is desirable to provide an airway balloon dilator that is capable of controlled cutting of scar tissue.
  • the present invention provides an airway balloon dilator for use to quickly re-establish laryngeal, tracheal or bronchial luminal patency to restore airflow in a way that avoids excessive trauma to the patient.
  • One aspect of the invention provides an apparatus for performing an airway balloon dilation procedure at the site of a stenosis in the airway of a patient, the apparatus comprising a central axis, a hollow core adapted to allow the patient to be ventilated therethrough, an inflatable outer balloon having an external surface, and at least one inflatable inner balloon, the apparatus being insertable into the airway of a patient for movement of the balloons therein between a deflated configuration and an inflated configuration, the at least one inner balloon configured to inflate inside the outer balloon yet separately from the outer balloon.
  • Another aspect of the invention provides a method for performing an airway balloon dilation procedure at the site of a stenosis in the airway of a patient, the method comprising: (1) inserting an apparatus into the airway, the apparatus including a central axis, a hollow core adapted to allow the patient to be ventilated therethrough, an inflatable outer balloon having an external surface, and at least one inflatable inner balloon, the apparatus being insertable into the airway of a patient for movement of the balloons therein between a deflated configuration and an inflated configuration, the at least one inner balloon configured to inflate inside the outer balloon yet separately from the outer balloon; (2) advancing the apparatus within the airway until the outer balloon is across the stenosis; and (3) inflating the balloon to cause and allow the external surface of the balloon to expand upon and dilate the stenosis.
  • Another aspect of the invention provides an apparatus for performing an airway balloon dilation procedure at the site of a stenosis in the airway of a patient, the apparatus comprising a central axis, a hollow core adapted to allow the patient to be ventilated therethrough, an inflatable, dumbbell-shaped outer balloon having an external surface, at least one inflatable inner balloon, a flexible support member mounted along the central axis of the apparatus and on the external surface of the outer balloon, the flexible support member being substantially compliant with the external surface of the outer balloon during movement therewith, and at least one microsurgical blade attached to the support member and adapted to form an effective cutting edge upon inflation of the outer balloon, the apparatus being insertable into the airway of a patient for movement of the balloons therein between a deflated configuration and an inflated configuration, the at least one inner balloon configured to inflate inside the outer balloon yet separately from the outer balloon, the dumbbell shape of the outer balloon adapted to hold the outer balloon in position over the stenosis, and the at least one blade adapted to form an
  • FIG. 1 is a perspective view of one embodiment of the balloon dilator of the present invention.
  • FIG. 2 is a perspective view of one embodiment of the balloon dilator in which the outer balloon has a dumbbell shape and multiple inner balloons.
  • FIG. 3 is a perspective view of a flexible support member having microsurgical blades, the support member adapted to fit over the outer balloon according to one aspect of the invention.
  • one embodiment of the present invention is an apparatus 10 for performing an airway balloon dilation procedure at the site of a stenosis in the airway of a patient, the apparatus comprising an inflatable outer balloon 12 which has an external surface 14 .
  • the apparatus also comprises a central axis 16 , a hollow core 18 , and at least one inflatable inner balloon 20 adapted to inflate inside the outer balloon.
  • the apparatus 10 is typically insertable into the airway of a patient for movement of the balloons 12 , 20 between a deflated configuration and an inflated configuration.
  • the inner balloon 20 is designed to inflate inside the outer balloon 12 yet separately from the outer balloon, adding the ability of the apparatus to produce high dilation pressures without balloon rupture.
  • the hollow core 18 traverses the entire apparatus 10 .
  • the hollow core connects via a proximal ISO connector to an oxygen source such as an anesthesia circuit or the like, and is designed to allow the patient to be ventilated upon inflation of the balloons during the procedure, when the airway is otherwise occluded.
  • the hollow core 18 is typically in the form of a central ventilating tube which is necessarily strong to prevent the pressure of the balloons from crushing the ventilating tube.
  • the structure of the hollow core 18 is typically similar to a small endotracheal tube with a dilating cuff, and the tube may be reinforced, e.g. with wire, in the area of the cuff.
  • one embodiment of the invention is a balloon dilator apparatus 30 in which the inflatable outer balloon 32 is dumbbell-shaped.
  • This dumbbell shape typically has a variable thickness at the proximal 34 and distal 36 ends of the balloon which allows the outer balloon 32 to stay in position over the stenosis during inflation.
  • the apparatus 30 can include a plurality of inner balloons 40 , 42 , 44 , wherein inner balloon 44 is contained inside inner balloon 42 , which is contained inside inner balloon 40 . All of the inner balloons 40 , 42 , 44 are contained inside outer balloon 32 , and are typically separately inflatable. Such an embodiment could be used with larger diameter outer balloons, e.g. between about 10 to about 20 mm.
  • the inner balloons 40 , 42 , 44 can be either dumbbell shaped or a “double cone” shape as seen with most angioplasty type balloons, and are inflated sequentially if higher pressures cannot be achieved by the outer balloon. Having a balloon dilator that incorporates multiple interconnected smaller balloons can achieve the desired pressure without risking balloon rupture during inflation.
  • the proximal 34 and distal 36 ends of the outer balloon 32 inflate first, forming the “dumbbell” shape, thereby trapping the stenotic airway segment at the central portion 38 of the balloon 32 , so that the outer balloon 32 does not slip out of position. Then, as the pressure in the balloon is increased, the central portion 38 of the balloon fully inflates at the site of the stenosis.
  • one embodiment of the invention can include a flexible support member 50 that can fit over the apparatus, specifically fitting over the outer balloon.
  • the flexible support member 50 is typically made of a polyurethane material and includes a central axis 56 mounted along the central axis of the apparatus.
  • the support member is adapted to fit over the external surface of the outer balloon, and is typically substantially compliant therewith during inflation and deflation.
  • Support member 50 also includes at least one microsurgical blade, and in FIG. 3 two surgical blades 52 are attached. Blades 52 form an effective cutting edge upon inflation of the outer balloon.
  • Blades 52 are typically made of stainless steel, and are elongated and permanently mounted on the flexible support member 50 .
  • the blade axis 54 is parallel to the central axis 56 of the support member 50 , which is substantially parallel to the central axis of the apparatus.
  • Having surgical blades 52 present on the apparatus during dilation typically permits controlled cutting or lysis of any scar tissue present in the patient's airway.
  • the blades 52 should be clearly marked so that users can avoid inadvertently cutting themselves during placement of the support member 50 over the outer balloon.
  • the blades 52 lay flat on the surface of the support member prior to use and prior to inflation of the outer balloon 12 , and then when the outer balloon reaches a certain pressure upon inflation the blades 52 will typically “stand up” or otherwise protrude or expose their cutting edge atop the flexible support member 50 .
  • the exposed edge of the blade 52 typically only protrudes between about 0.2 to about 0.4 mm, and the length of the blade is typically less than the length of the outer balloon 12 .
  • each of the blades being separated from the other blades so that each blade is free to move from a relatively flat position to a cutting position on the flexible support member upon inflation of the outer balloon.
  • the airway balloon dilation procedure is typically performed at the site of a stenosis in the airway of a patient (i.e. the larynx, trachea or bronchi).
  • the surgeon or clinician first inserts the apparatus 10 into the airway, then advances the apparatus within the airway until the outer balloon 12 is across the stenosis.
  • the surgeon or clinician inflates the outer balloon 12 to cause and allow the external surface 14 of the outer balloon 12 to expand upon and dilate the stenosis.
  • the inner balloon 20 is then slowly inflated. Typically the inner balloon 20 is inflated after the inflation of the outer balloon 12 .
  • the balloons are typically inflated from between about 30 to about 120 seconds.
  • the apparatus 10 can also be threaded over a guidewire (not shown) which fits through the hollow core 18 and is positioned across the stenosis. Repeat inflation-deflation cycles can be done if airway narrowing remains after the initial attempt.
  • the size of the balloon is first selected by the clinician, which depends upon the size of the stenosis in the patient's airway.
  • the balloon size is typically between about 10 mm to about 40 mm in length.
  • the outer balloon is positioned over the stenosis and then each balloon is individually dilated to the desired pressure with a balloon pump, typically to between about 8 to about 20 atmospheres. After these pressures are maintained for a predetermined period of time, typically between about 60 to about 180 seconds, the balloons are deflated and the clinician determines if repeat inflation is necessary. Repeat inflation can be safely performed if there is no obvious trauma to the airway.
