Appeal No. 1996-3547 Page 2
Application No. 08/089,854
BACKGROUND
The appellants' invention relates to a prosthetic device
useful for binding to bone. An understanding of the invention
can be derived from a reading of exemplary claims 68, 106 and
107, which are reproduced below.
68. A prosthetic device for binding to bone, said prosthetic
device having a shape suitable for placing the prosthetic device
in contact with bone for binding to bone, said prosthetic device
comprising a polymer, said polymer being a segmented
thermoplastic polymer comprising a plurality of recurring units
of a first component and of a second component, wherein said
first component comprises units having the formula:
-OLO-CO-R-CO-, wherein L is selected from the group
consisting of: (i) a divalent radical remaining after removal of
terminal hydroxyl groups from a poly(oxyalkylene) glycol; and
(ii) a polymer including a first moiety and a second moiety, said
first moiety being a polyalkylene glycol and said second moiety
being selected from the group consisting of glycine anhydride,
alloxan, uracil, 5,6-dihydrouracil, glycolic acid, lactic acid,
and lactones, and R is a divalent radical remaining after removal
of carboxyl groups from a dicarboxylic acid, and said second
component comprises units having the formula:
-OEO-CO-R-CO,
wherein E is an alkylene radical, and R is a divalent radical
remaining after removal of carboxyl groups from a dicarboxylic
acid.
106. A prosthetic for binding to bone, said prosthetic
device having a shape suitable for placing the prosthetic device
in contact with bone for binding to bone, said prosthetic device
comprising a polymer, said prosthetic device selected from the
group consisting of: (a) a covering of middle ear bones; (b) an
artificial ossicle; (c) an artificial palate; (d) a sinus
ventilation tube; (e) an orthopedic implant coated with said
polymer; (f) a distal portion of a hip stem; (g) a mastoid repair
device; (h) an ear canal wall; (i) a closure of the nasal septum;
