Abstract
Abstract An applicator is disclosed for injecting or releasing a fluidic or solid substance into a cavity or tissue of a patient. The applicator is used to release a contained substance along the length of the applicator when the applicator has been inserted and positioned in the patient. Thus, if required, the substance to be released can easily be dispensed along a particular path such that a proper amount of the substance is dispensed along the path. In particular, the applicator of the present invention is useful in placing absorptive foam pads within a nasal cavity and in inserting implants into a breast.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
145 words
An applicator assembly for providing an insert substance in a body receiving area, comprising: a housing having a length and a chamber running substantially the entire length of the housing, an opening in a side of said housing running substantially the length of the housing, means, running substantially the entire length of the housing, for restricting the side opening to the housing and for holding said substance within said chamber, said housing further having an open end with an opening and a distal end, a plunger, which is sized to be inserted into the housing end opening, including a shaft which extends substantially the length of the chamber, said plunger and said distal end together including means for urging the substance out the opening in the side of said housing as the plunger is advanced through the housing in the direction of the distal end.
Claim 2
Dependent Claim
145 words
An applicator assembly for providing an insert substance in a body receiving area, comprising: a housing having a length and a chamber running substantially the entire length of the housing, an opening in a side of said housing running substantially the length of the housing, means, running substantially the entire length of the housing, for restricting the side opening to the housing and for holding said substance within said chamber, said housing further having an open end with an opening and a distal end, a plunger, which is sized to be inserted into the housing end opening, including a shaft which extends substantially the length of the chamber, said plunger and said distal end together including means for urging the substance out the opening in the side of said housing as the plunger is advanced through the housing in the direction of the distal end.
Claim 3
Dependent Claim
35 words
An assembly, as claimed in claim 1, wherein: said means for restricting and holding includes a retaining member removably joined to said housing and including a panel member that encloses a length of said chamber.
Claim 4
Dependent Claim
29 words
An assembly, as claimed in claim 2, wherein: said retaining member is moved to permit said insert substance to move in a direction substantially perpendicular to said housing length.
Claim 5
Dependent Claim
29 words
An applicator assembly, as claimed in claim 2, wherein: said retaining member is moved to permit said insert substance to move from said chamber under a force of gravity.
Claim 6
Dependent Claim
24 words
An assembly, as claimed in claim 2, wherein: said panel member has a predetermined contour for following a path in the body receiving area.
