Filed:

Oct 1, 1998

Appl. No.:

09/164928

Inventors:

George A. Arndt - Madison WI

Assignee:

International Classification:

A61M 1600

US Classification:

12820026, 12820629

Abstract:

A bite block for use with an airway conduit comprises an elongated arcuate body having a U-shaped channel defined therein and at least one end flange at a proximal end of the arcuate body, wherein the U-shaped channel corresponds in shape to a predetermined shape of a tubular conduit of an airway such as a laryngeal mask airway and to a human oral-pharyngeal cavity. The U-shaped channel is open to the lingual surface and can be inserted over a tubular conduit of a properly inserted laryngeal mask airway.

Abstract:

An apparatus and method for blockage of a peripheral nerve of a patient utilizes simultaneous continuous electrical nerve stimulation and visualization of the nerve using 2D ultrasound. A hyperechoic stimulating block needle is provided for insertion into the patient. The needle includes a hollow metal conduit, and a generally non-conductive covering extending along the shaft of the conduit. An echogenic surface capable of scattering and reflecting ultrasound waves for enhanced visualization extends along at least a portion of the length of the needle. The needle is inserted into the patient, and the needle tip is optimally aligned in proximity with the nerve by simultaneous visualization with 2D ultrasound and by electrical nerve stimulation. Once the needle is optimally placed with regard to the nerve, a drug may be injected through a bore of the needle into the patient.

International Classification:

A61M 5/00

US Classification:

604020000

Abstract:

An assembly and method for continuous blockage of a nerve in a patient. The assembly includes a needle comprising a hollow needle conduit having a shaft portion and a tip portion, a generally non-conductive layer disposed along a length of the conduit shaft portion, and an echogenic surface extending along at least a portion of the needle. A catheter having a bore for transmittal of an anesthetic to the nerve is receivable in the shaft portion of said needle. Following insertion of the needle tip in the vicinity of the nerve by electrical nerve stimulation and ultrasound visualization, the catheter is passed through the needle conduit such that the distal end of the catheter extends beyond the distal tip of the needle. The catheter has an echogenic portion, such as a ribbon wrapped around the distal end of the catheter, and the catheter echogenic portion is guidable in the vicinity of the nerve under ultrasound imaging. Following placement of the catheter, the needle may be removed, leaving the catheter in position for delivering continuous, spaced doses of the anesthetic over a selected period of time.

Inventors:

George Arthur Arndt - Madison WI

Assignee:

Wisconsin Medical, Inc. - Madison WI

International Classification:

A61B 1267
A62B 904

US Classification:

600114

Abstract:

An apparatus and method for accomplishing simultaneous bronchoscopy and airway instrumentation and securing the instrument in place using an adjustable threaded gastight seal. The apparatus consisting of a hollow elongated manifold for simultaneous fiberoptic bronchoscopy through a fiberoptic port (4) and introduction a secondary tubular instrument (2) through a threaded secondary instrument port (5) while maintaining mechanical ventilation of a intubated patient using a ventilation port (7) and endotracheal tube connection port (6). The secondary instrument port (5) is constructed in a manner to allow introduction of a tubular instrument into the airway and form an adjustable gastight seal. It consists of a compressible perforated diaphragmatic seal (17) sandwiched between a threaded secondary instrument port and threaded perforated secondary instrument cap (18) so that the threaded cap may be torqued into the threaded secondary port (5) compressing the compressible diaphragmatic seal (17) against the inserted secondary instrument (2) forming airtight adjustable seal and affixing the secondary instrument in place. In addition, the secondary instrument port (5) allows chronic instrumentation following the removal of the fiberoptic bronchoscope (3) or reinspection.

Assignee:

Cook Incorporated - Bloomington IN

International Classification:

A61B1/22

US Classification:

600120

Abstract:

A balloon-tipped, wire-guided double lumen, endobronchial blocker catheter (6) is provided for insertion into the tracheal bronchial tree using a fiberoptic bronchoscope (2). The catheter incorporates a removable wire guide (14), which runs the entire length of the catheter exiting the tip as a small unencased wire loop (12). The small unencased wire loop is positioned around the circumference of a fiberoptic bronchoscope and when advanced along the fiberoptic bronchoscope thereby allows the catheter to navigate the airway using the fiberoptic bronchoscope as a guide or stint allowing the catheter to reach portions of the lung where access is difficult due to sharp bends in the tracheal bronchial tree. A balloon (8) thereof is inflated to provide obstruction of a portion of the lung from ventilation. The long wire guide loop is removable allowing communication of the blocked segment with the proximal end of the catheter.

International Classification:

A61M 16/04
A61M 16/00
A61B 1/267

Abstract:

An airway manifold includes a manifold body having an upper body portion and a lower body portion. The body portions are engaged such that the upper body portion is rotatable relative to the lower body portion, whereby a generally hollow interior space is defined. The lower body portion has a port open to the interior space, and the upper body portion includes a plurality of ports open to the interior space. A first upper body port is axially alignable with the lower body port to define a substantially linear passageway therebetween when the upper body portion is at a first rotatable position relative to the lower body portion. A second upper body port is axially alignable with the lower body port to define a substantially linear passageway therebetween when the upper body portion is at a second rotatable position.
