Abstract
The present invention relates to a device for repair of a region within an ear via a natural orifice, the device comprising a body. The body comprises a first port for visibly identifying the region to be sealed, the region being inside the ear; and a second port through which a seal can be introduced into the ear through the device. The region comprises a perforation of a tympanic membrane of the ear and the device is a speculum. The present invention also relates to method for repairing a perforation in a tympanic membrane using the same device.
Claims13
A system for repair of a region within a natural orifice of an ear, comprising:
- a device for repair of a region within the natural orifice of the ear, comprising:
- a body that tapers distally to facilitate introduction of a distal end of the device into the ear, the body comprising:
- a first port comprising a magnifying member, the first port being for visibly identifying the region to be sealed and being arranged to maintain visibility of the region during delivery of a seal through a second port, the region being inside the ear, wherein the magnifying member magnifies the visibly identified region inside the ear and wherein the second port is a port through which the seal can be introduced into the ear through the device;
- the seal for covering the region being sealed;
- and
- an introducer for introducing the seal through the device, into the ear via the natural orifice, so that the introducer extends at least into a perforation in the region.
A method for repairing a tympanic membrane through a natural orifice of an ear, comprising:
- inserting, through a device comprising a body that tapers distally to facilitate introduction of a distal end of the device, into the ear, the body comprising a first port comprising a magnifying member, the first port being for visibly identifying a region within the ear via the natural orifice to be sealed and being arranged to maintain visibility of the region during delivery of a seal through a second port, the region being inside the ear, wherein the magnifying member magnifies the visibly identified region inside the ear and wherein the second port is a port through which the seal can be introduced into the ear through the device, an introducer into the ear via the natural orifice, so that the introducer extends at least into a perforation in the tympanic membrane;
- delivering the seal from the introducer to a distal side of the tympanic membrane;
- and attaching the seal to the distal side.
A kit comprising:
- a device comprising a body that tapers distally to facilitate introduction of a distal end of the device into an ear, the body comprising:
- a first port comprising a magnifying member, the first port being for visibly identifying a region within the ear via a natural orifice to be sealed and being arranged to maintain visibility of the region during delivery of a seal through a second port, the region being inside the ear, wherein the magnifying member magnifies the visibly identified region inside the ear and wherein the second port is a port through which the seal can be introduced into the ear through the device;
- a graft for covering the region being repaired;
- and
- an introducer for introducing the graft through the device.
