摘要:
An implant device for placement within a salivary gland duct having a first end adjacent a parotid gland and a second end adjacent a submandibular gland. The implant device comprises an elongate body having a lumen, and a first and a second plate offset from the proximal end of the elongate body. The first plate is located on one side of the elongate body and the second plate is located on the other side of the elongate body. The first plate includes a first and a second hole operable to suture the first plate to a location adjacent the parotid gland. The second plate includes a first and a second hole operable to suture the second plate to a location adjacent the submandibular gland.

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.
摘要:
This invention relates to a dual-cannula tracheostomy device comprising an outer cannula and an inner cannula for insertion into the trachea of patients with normal-sized and extra-long stomas. The inner cannula comprises an interlocking means which interacts with a connecting means on the outer cannula in order to stabilize the inner cannula when it is inserted in the outer cannula. The inner cannula may also comprise a gripping means, such as ridges, which improve handling of the inner cannula during its insertion and removal from the outer cannula. The invention further comprises an obturator to help guide the outer cannula while it is being inserted into the trachea. The obturator similarly comprises an interlocking means which interacts with the connecting means on the outer cannula to stabilize the obturator while it is inserted in the outer cannula. Finally, the invention comprises a method of inserting the tracheostomy device into the trachea of a patient.

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.
摘要:
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.
摘要:
Disclosure is made of an improvement in the T-shaped tracheal stents and in the tracheal cannulas of the prior art, permitting one to conveniently have a complete and unitary unit including a closure member affixed to the device of the invention. Unidirectional retention sleeves are also described, which may be used in conjunction with the cannulas and the stents of the invention.

摘要:
An implant device having a proximal end and a distal end, and a suturing fixture offset from the proximal end. 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.

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.
