International Classification:

A61F 1100

US Classification:

606108, 600237, 12820026

Abstract:

The present invention provides a mouthpiece assembly for establishing a protected airway for a patient. The mouthpiece assembly comprises a generally elliptical tubular bite block having a generally elliptical passageway formed therethrough. The mouthpiece assembly further comprises a generally elliptical front shield attached to the front end of the tubular bite block portion. The front shield has a central opening in communication with the passageway for receiving medical instruments therethrough and a strap opening adjacent each of the opposing edge portions. At least a portion of the front shield is curved rearward and is flexible to allow the at least a portion of the front shield to conform to the patients facial structure. The mouthpiece assembly also comprises a tongue depressing member extending rearwardly and downwardly from the rearward end of the bottom wall of the tubular bite block, and a resilient cushioning sleeve formed around at least a portion of the tubular bite block. A headstrap has an elongate belt member adapted for insertion through the strap openings to connect the belt ends to the front shield.

International Classification:

A61M 500

US Classification:

604256, 604164, 604167, 604246, 604278

Abstract:

A modular trocar assembly having a cannula, a passive valve seal assembly and an instrument seal assembly all releasably joined to define a central axial bore, where the passive valve seal assembly contains a valve seal which prevents passage of gas through the trocar assembly into the atmosphere when no instrument is inserted but which opens to allow for insertion of an instrument, and where the instrument seal assembly contains an instrument reducer seal which prevents passage of gas through the trocar assembly into the atmosphere when an instrument is inserted through the valve seal. The passive valve seal assembly and the instrument seal assembly are preferably composed of plastic so as to be disposable, while the cannula is preferably composed of a sterilizable material to enable reuse.

International Classification:

A61B 1732

US Classification:

606113, 606110, 606 47

Abstract:

A surgical instrument and method for facilitating the capture of objects during surgery are provided. The surgical instrument comprises a flexible tube having a proximal tube end and a distal tube end, the flexible tube defining a cable passageway and being configured for insertion of at least a distal portion of the flexible tube into a body cavity of a patient. The surgical instrument further comprises a flexible cable having a proximal cable end and a distal cable end. At least a portion of the flexible cable is slidably disposed in the cable passageway. A snare loop having a loop member is attached to the distal cable end. The snare loop and the cable are adapted so that the snare loop can be selectively retracted within the cable passageway by sliding the flexible cable proximally within the cable passageway. The snare loop and the cable are also adapted so that at least a portion of the snare loop can be selectively extended from the distal tube end by sliding the flexible cable distally within the cable passageway. The loop member is adapted for selectively encircling and engaging at least a portion of an object in the body cavity.

International Classification:

A61M005/178

US Classification:

60416703

Abstract:

A surgical seal assembly which forms a seal about a surgical instrument thus preventing the leakage of fluids, gases and the like. The surgical seal assembly includes a valve with a reinforcing layer. The reinforcing layer is preferably a woven fabric and an elastomeric material such as silicon or other similar material. The reinforcing layer expands proportionally with the insertion of the surgical instrument, is tear or puncture resistant and is designed to accommodate off axis alignment and insertion of the surgical instrument.

US Classification:

606 47, 606113, 606110

Abstract:

A surgical instrument and method for facilitating the capture of objects during surgery are provided. The surgical instrument includes a flexible tube defining a cable passageway and being configured for insertion of at least portion of the flexible tube into a body cavity of a patient. The surgical instrument further includes flexible cable slidably disposed in the cable passageway. A snare loop is attached to the cable end and both are adapted so that the snare loop can be selectively retracted or extended within the cable passageway by sliding the cable proximally or distally within the cable passageway. The loop member is adapted for selectively encircling and engaging at least a portion of an object in the body cavity. The system also comprises a tether, the tether attached to the loop member at one end and to the flexible tube at the other, so that extension of the flexible cable causes the snare loop to deform in a predetermined manner.

US Classification:

60416703, 604256

Abstract:

A surgical instrument valve assembly is provided with a valve seal where the upper portion of the valve seal is rigidly mounted to the body of the valve assembly. The lower portion of the valve seal is configured to allow some radial movement while the upper portion of the valve seal remains rigidly mounted within the valve assembly. The valve seal may be provided with stay that prevents the valve seal from inverting when an instrument in withdrawn from the valve assembly.

Abstract:

A male urinary incontinence control device comprising dorsal and ventral arms is presented. The dorsal clamping portion is configured for engaging a dorsal surface of a user's penis. The ventral clamping portion is configured for engaging a ventral surface of a user's penis. The device also comprises an adjustable hinge connecting the hinge end of the dorsal arm clamping portion to the hinge end of the ventral arm clamping portion. The adjustable hinge comprises a pivot fixed to one of the ventral and dorsal arms and about which the other of the ventral and dorsal arms can be selectively rotated between a closed position wherein the dorsal arm clamping portion is in opposition with the ventral arm clamping portion and an open position. The location of the pivot relative to the other of the ventral and dorsal arms is selectively adjustable to establish a desired spacing between the ventral and dorsal arms when in the closed position.
