6 results about "Turbinates" patented technology

The present disclosure describes devices for intranasal drug delivery to targeted regions and sub-regions of a nasal cavity of a subject, including the turbinates. The devices may have a housing with a dispensing element, and a positioning or trigger element coupled to the housing that positions the dispensing element within the nasal channel and limits its depth of insertion. The dispensing element may comprise a side opening for dispensing a composition. Devices of the present disclosure may provide a convenient and effective way to deliver compositions intranasally to the targeted regions and subregions while limiting off-target delivery.

A catheter assembly for use in septoturbinatoplasty procedures. The catheter has a shaft and a primary balloon which comprises a base for positioning against the nasal floor, a roof opposed from the base and a side surface extending therebetween for bearing against a nasal septum and / or an inferior turbinate. The base has a width greater than the roof in a direction transverse to the axis of the shaft. The balloon can be inserted into a patients nasal cavity and inflated to realign the patient's septum and / or treat the turbinate.

The utility model relates to the technical field of medical instruments, and provides a turbinate blood taking needle guard which comprises a three-edged needle, and an inner sleeve used for fixing the three-edged needle is arranged on the outer side of the three-edged needle in a sleeved mode. According to the turbinate blood taking needle sleeve, a three-edged needle inserted into the inner sleeve can be more conveniently fixed through the clamping plate in the inner sleeve, the three-edged needle can be more conveniently replaced, the three-edged needle is driven by the inner sleeve to slide in the outer sleeve, the exposed length of the three-edged needle is adjusted, and due to the fact that tail thorns on the inner sleeve are clamped through the adjusting ring, the tail thorns can be conveniently fixed and replaced. When the adjusting ring slides on the outer sleeve, the inner sleeve can be driven to slide to a proper distance in the outer sleeve, and the adjusting ring can be fixed on the outer sleeve through the fixing assembly on the adjusting ring, so that the outward leakage length of the three-edged needle is fixed, and the distance of the three-edged needle in the outer sleeve through the inner sleeve can be checked through the visual window. The convenience of adjusting the push-out distance of the three-edged needle by the whole needle sleeve is improved.

Devices and methods for more effective cryoablation of a posterior nasal nerve. The cryoablation tip of the device is paddle-shaped, with broad, flat, overall rectangular outline with notches on the sides to create a metacentric outline. One side of the cryoablation tip is conductive, while the opposing side is highly non-conductive. Corner portions of the tip are also non-conductive. Intermediate portions of the side-edge surfaces conductive, and are configured as recesses or notches in the side edge. In use, the system will be inserted into the nasal cavity of a patient, with conductive surfaces of the cryoablation tip disposed in contact with portions of the turbinate lining overlying a posterior nasal nerve, and operated to cool those portions to ablate the posterior nasal nerve. The insulative portion of the cryoablation tip protects remaining surrounding tissue from cryoablation.

A septum support or nasal splint that is insertable within a nasal cavity of a patient to maintain a position of a septum of the patient includes a base and a first side member that is positioned on a first side of the base and that extends upward from the base. The first side member is configured to contact the septum of the nasal cavity. The septum support also includes a second side member that is positioned on a second side of the base and that extends upward from the base. The second side member is configured to contact a turbinate of the nasal cavity so as to reinforce the first side member. A lower end of the second side member is securely connected to the base or first side member and an upper end of the second side member is not attached to the first side member.
