Abstract: The present invention relates to devices used in the management of bodily airways including tracheostomy tubes, laryngectomy tubes, bronchial stents, bronchial Y-tubes, bronchial TY-tubes, and nasal stents. The devices may comprise a protective coating to prevent the accumulation of mucus, crusting and granulation on or around airway management devices, as well as prevent adhesion to tissues which can cause bleeding upon removal, and prevent build-up of blood, or blood clots, to the stent.

The suturing fixture has a profile that extends from the surface of the elongate body. For example, the suturing fixture may have the shape of a cone, or the shape of a disc. The implant device may be used for placement within a salivary gland duct.

Abstract: Devices used in the management of bodily airways including bronchial and tracheal stents, bronchial Y-tubes, bronchial TY-tubes, nasal septal buttons, and nasal stents. The present invention also relates to devices used to manage the esophagus, such as salivary bypass tubes. These devices may comprise a fiber mesh imbedded in the walls of the device in order to provide integrity to the device wall and permit anchoring and suturing of the device.

Abstract: A cannula for placement within a salivary gland duct having a first end adjacent an oral cavity and a second end adjacent a salivary gland is provided. The cannula includes an elongate body having a lumen and a first and a second plate offset from a proximal end of the elongate body. The first plate is located on one side of the elongate body and the second plate is correspondingly located on the other side of the elongate body and adjacent the first plate. The first plate has a first hole that is operable to suture the first plate to a location adjacent the first end of the salivary duct adjacent the oral cavity, whereby upon placement of the cannula within the salivary gland duct, saliva flows through the elongate body's lumen from the salivary gland to the oral cavity.

Abstract: Device for delivering an airway stent to patients and methods of using the stent. The device may comprise a sheath to position the stent in the airway, and a fiber scope or ventilator to assist in delivering the stent. The device may be used to deliver, for example, a tracheal or nasal stent. Further, a device for folding stents and a device for loading folded stents into a stent delivery device.

Abstract: An apparatus and method for implanting a surgical apparatus including a first flange having an opening, a second flange having an opening, and a shaft having a lumen connecting the first and second flange openings. The surgical apparatus is inserted into a stoma formed in the trachea of a patient. The surgical apparatus receives and secures an oxygen supply line for patients who have difficulty breathing.

Abstract: A pharyngometer or similar wavetube-based apparatus which includes a wavetube which is detachable from the electronic platform. As the wavetube includes no electronic components, the wavetube can be sterilized thermally or chemically between patients without damaging the electronics of the electronic platform. The wavetube is attached to the electronic platform by a tab in the electronic platform which fits into a lateral groove within the wavetube. Similarly, a threaded member in the electronic platform engages a threaded aperture in the wavetube.

Abstract: A cannula is described for insertion within the nose of a patient to provide drainage or to allow for postoperative suction of the sinus after surgery. The cannula is formed as an elongated tubular section with an anchoring end for insertion into the sinus. At the anchoring end of the cannula reinforced leaflets are provided as drainage channels and to serve as the anchoring aspect of the cannula.

Abstract: A device for dilating nasal passageway which includes a resilient bar having pads on opposite ends for insertion into respective nasal passageways and the bar when bent causes a biasing outward force on the pads to dilate the anterior section of the nasal cavity with said bar having notches thereon which can be selectively cut to reduce the bearing force on the pads.

Abstract: In a device for acoustic imaging of internal morphology of the respiratory tract which utilizes a hollow acoustic pipe having a speaker on one end and microphones on its side wall the improvement comprising a disposable tube or sleeve which is intended to be coextensive with the pipe, having a filter at its far end and filters to fit over the microphones along with a lip or ring at its outer end so as to avoid cross-contamination between patients whose breath enters the pipe.

Abstract: A device for allowing visual examination of the swallowing of fluids by an infant which includes a nipple mounted housing, a feeding tube for feeding fluid into the nipple, openings in the nipple to allow the fluid to pass or be sucked therethrough, a further opening centrally located in the nipple through which an endoscope is passed to allow for such visual examination.

Abstract: A method of acoustically imaging a portion of the morphology of a subject which includes the steps of utilizing a burst of pulses for which reflections are recorded prior to analyzing and plotting the data generated thereby.

Abstract: In a device for acoustic imaging of internal morphology of the respiratory tract which utilizes a hollow acoustic pipe having a speaker on one end and microphones on its side wall the improvement comprising a disposable tube or sleeve which is intended to be coextensive with the pipe, having a filter at its far end so as to avoid cross-contamination between patients whose breath enters the pipe while protecting the speaker from humidity.

Abstract: Single hand supportable and operable apparatus for providing an output signal characteristic of the morphology of a respiratory tract includes an acoustic pipe for exchanging acoustical energy with the tract. The pipe has an open first end in communication with an opening in the respiratory tract. A transducer, such as a loudspeaker, is coupled to the pipe for launching acoustical energy into the pipe, producing an incident wave towards the opening in the tract and a reflected wave to form a transient wave field in the pipe representative of the morphology of the tract. Preferably, first and second pressure wave sensing transducers, such as microphones, mounted along the length of the pipe in spaced relationship provide first and second transduced signals representative of the transient wave field.

Abstract: A laryngeal stent for supporting anatomical features of the mammalian larynx, including a human larynx is formed by a gas-inflatable envelope fabricated from a resilient, deformable material can conform to the anatomical surfaces of the larynx within the mammal's esophagus when pressurized by the gas. In preferred embodiment stents, the surface of the envelope is coarse, allowing for the venting of air between the laryngeal surfaces and the envelope. However, the stent conforms so closely to the anatomical features of the larynx that sutures are not required to anchor the stent in place.

Abstract: An implantable device used in treating glaucoma includes a movable plate shaped and sized to fit in a single quadrant of an eye to provide maximum surface area. A drainage tube is attached to the plate and has a distal end for insertion into the anterior chamber of the eye to drain fluid. A valve is disposed in the tube to control the fluid pressure within the eye and prevent hypotony. The plate is made of soft surgical grade polymeric material to prevent extrusion from the body.

Abstract: A nasal splint is described to separate the mucoperiosteum within a nasal cavity. The splint includes an elongate base sized and shaped to separate the inferior conchae. A flexible wing extends away from the base to separate the walls of the middle conchae when the splint is in place within the nasal cavity. A hollow tube is also provided on the base for defining an air passage.
