Abstract
Abstract The present invention is a device including a hollow tube which contains a supply of beeswax which can be controllably extruded for use. The hollow tube has a plunger-like device mounted at its side or at one end to permit external pressure to be provided to compress the contents of the tube. An opening is located at the end of the tube opposite the plunger through which the wax is extruded. The size of the opening is determined by the size of the bone pore to be filled and the quantity of wax desired. A metal tip is affixed adjacent to the opening for applying the wax to the bone. The length and width of the metal tip is determined by the size of the bone pore to be filled. A single hollow tube may be used for two different size applicators by dividing the tube with a partition to form two chambers, each of which is filled with beeswax.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A device for applying a sealant to a bone pore for inhibiting bleeding when surgically cutting through bone, said device comprising: a hollow tube having a partition therein defining a first chamber and a second chamber, said first chamber having a first opening at its end, said first opening having a first diameter and said second chamber having a second opening at its end, said second opening having a second diameter, said first diameter being larger than said second diameter for dispensing a wider stream of sealant than is dispensed by said second opening; a plunger means corresponding to each said chamber for placing a compressive force upon said sealant; an applicator tip adjacent to each said opening for applying said sealant extruded from said opening to said bone pore.
Claim 2
Independent Claim
130 words
A device for applying a sealant to a bone pore for inhibiting bleeding when surgically cutting through bone, said device comprising: a hollow tube having a partition therein defining a first chamber and a second chamber, said first chamber having a first opening at its end, said first opening having a first diameter and said second chamber having a second opening at its end, said second opening having a second diameter, said first diameter being larger than said second diameter for dispensing a wider stream of sealant than is dispensed by said second opening; a plunger means corresponding to each said chamber for placing a compressive force upon said sealant; an applicator tip adjacent to each said opening for applying said sealant extruded from said opening to said bone pore.
Claim 3
Dependent Claim
42 words
A device as in claim 1 wherein a first applicator tip is adjacent to said first opening and a second application tip is adjacent to said second opening, said first applicator tip being broad and short relative to said second applicator tip.
Claim 4
Independent Claim
114 words
A method of applying a sealant to a bone pore for inhibiting bleeding when surgically cutting through the bone which comprises: selecting a hollow tube with at least one chamber and an opening at an end of each said chamber; filling each said chamber of said hollow tube with said sealant; inserting a plunger in each said chamber for placing a compressive force upon said sealant whereby said sealant may be extruded through said opening; attaching an applicator tip adjacent to said opening; compressing said plunger; dispensing a desired amount of said sealant through said opening; and pressing said applicator tip against said dispensed sealant to force said dispensed sealant into said bore pore.
Claim 5
Independent Claim
114 words
A method of applying a sealant to a bone pore for inhibiting bleeding when surgically cutting through the bone which comprises: selecting a hollow tube with at least one chamber and an opening at an end of each said chamber; filling each said chamber of said hollow tube with said sealant; inserting a plunger in each said chamber for placing a compressive force upon said sealant whereby said sealant may be extruded through said opening; attaching an applicator tip adjacent to said opening; compressing said plunger; dispensing a desired amount of said sealant through said opening; and pressing said applicator tip against said dispensed sealant to force said dispensed sealant into said bore pore.
Claim 6
Dependent Claim
25 words
A method as in claim 3 further comprising inserting a partition within said hollow tube whereby a first chamber and a second chamber are formed.
