Claim 9

Dependent Claim 37 words

An apparatus as defined by claim 1, further comprising a breathing conduit, said breathing conduit adapted to bypass said expansible sealing cuff, so as to allow breathing through the nostril in which the device is operatively installed.

Claim 10

Dependent Claim 240 words

An intranasal device for controlling nasal hemorrhaging without direct pressure, said device adapted for insertion into a nasal cavity during a nasal operation or other nasal procedure, said device comprising: an elongated tubular element, having mounted thereon a blunt, tapered guiding end, adapted to facilitate manipulation of said device within the nasal cavity; an expansible low pressure sealing cuff, contiguous with said guiding end and adapted to be inflated by a source of pneumatic fluid; an inflation conduit, having a tubular passageway for transmitting said pneumatic fluid into and out of said expansible low pressure cuff, so as to inflate and deflate said cuff, respectively; a drainage conduit, adapted to be connected to a source of suction, said drainage conduit exhibiting a plurality of influent ports which enable blood, mucous and other debris to be suctioned from the nasal cavity; and an absorptive member, having a tapered configuration, exhibiting a smaller cross-sectional area at its proximal end and a larger cross-sectional area at its distal end, said tapered configuration adapted to provide maximum absorptivity within the nasal cavity, while leaving a substantial portion of the frontal nasal cavity clear for said nasal procedure, said absorptive member adapted to enclose said influent ports of said drainage conduit, so as to prevent soft tissue present in the nasal cavity from being suctioned into said influent ports and to evenly distribute said suction over substantially the entire surface area of said absorptive member.

Claim 11

Dependent Claim 240 words

An intranasal device for controlling nasal hemorrhaging without direct pressure, said device adapted for insertion into a nasal cavity during a nasal operation or other nasal procedure, said device comprising: an elongated tubular element, having mounted thereon a blunt, tapered guiding end, adapted to facilitate manipulation of said device within the nasal cavity; an expansible low pressure sealing cuff, contiguous with said guiding end and adapted to be inflated by a source of pneumatic fluid; an inflation conduit, having a tubular passageway for transmitting said pneumatic fluid into and out of said expansible low pressure cuff, so as to inflate and deflate said cuff, respectively; a drainage conduit, adapted to be connected to a source of suction, said drainage conduit exhibiting a plurality of influent ports which enable blood, mucous and other debris to be suctioned from the nasal cavity; and an absorptive member, having a tapered configuration, exhibiting a smaller cross-sectional area at its proximal end and a larger cross-sectional area at its distal end, said tapered configuration adapted to provide maximum absorptivity within the nasal cavity, while leaving a substantial portion of the frontal nasal cavity clear for said nasal procedure, said absorptive member adapted to enclose said influent ports of said drainage conduit, so as to prevent soft tissue present in the nasal cavity from being suctioned into said influent ports and to evenly distribute said suction over substantially the entire surface area of said absorptive member.

Claim 12
