Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
A surgical nasal septum splint made of one piece of flexible material, and characterized by two splint limbs having anterior ends joined together by an isthmus adapted to underlie the columella of the patient to provide an anchor to preclude accidental aspiration, and having free posterior ends for conjoint nasal insertion, each of the limbs having a flat inside surface to fit against the nasal septum.
Claim 2
Dependent Claim
66 words
A surgical nasal septum splint made of one piece of flexible material, and characterized by two splint limbs having anterior ends joined together by an isthmus adapted to underlie the columella of the patient to provide an anchor to preclude accidental aspiration, and having free posterior ends for conjoint nasal insertion, each of the limbs having a flat inside surface to fit against the nasal septum.
Claim 3
Dependent Claim
39 words
The splint as set forth in claim 1 in which said limbs each have an integral breathing tube extending substantially the length of the corresponding limb, said tube being sufficiently rigid to remain open notwithstanding tight packing for hemostasis.
Claim 4
Dependent Claim
27 words
The splint as set forth in claim 2 in which the flat inside surfaces of said limbs each generally conform to the configuration of the human septum.
Claim 5
Dependent Claim
33 words
The splint as set forth in claim 2 in which each of said limbs at its upper end is convexly curved and of reduced transverse dimension to facilitate placement in the nasal passage.
Claim 6
Dependent Claim
21 words
The splint as set forth in claim 4 in which the said isthmus is rounded to minimize discomfort to the patient.
Claim 7
Dependent Claim
52 words
The process of stabilizing the septum of a patient following nasal reconstruction, which comprises placing a one piece splint in the two nasal passages of the patient leaving an anterior bridge or isthmus part of the splint at the columella; thereafter suturing only the posterior end of the splint to the septum.
Claim 8
Dependent Claim
52 words
The process of stabilizing the septum of a patient following nasal reconstruction, which comprises placing a one piece splint in the two nasal passages of the patient leaving an anterior bridge or isthmus part of the splint at the columella; thereafter suturing only the posterior end of the splint to the septum.
Claim 9
Dependent Claim
41 words
The process as set forth in claim 6 in which said splint is provided with breathing tubes for both passages, said process being further characterized by the step of packing the nasal passages following said suturing with gauze or equivalent material.
