Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
A heart valve comprising: a base having an annular outside portion and a passage allowing the flow of blood through the base, valve means selectively movable relative to said base to open and close the passage to control the flOw of blood through the passage, a suturing collar surrounding the outside portion of said base, said collar having external cover means including porous material for accommodating live heart tissue to form a union between the cover means and heart tissues, said cover means having an inner surface, annular continuous means located about and engaging an annular portion of the inner surface to hold the cover means in engagement with the outside portion of the base, and heat cured core plastic material surrounded by said cover means, said core plastic material having an outer surface bonded only to the inner surface of the cover means and the continuous means during the heat curing of the core plastic material.
Claim 2
Dependent Claim
157 words
A heart valve comprising: a base having an annular outside portion and a passage allowing the flow of blood through the base, valve means selectively movable relative to said base to open and close the passage to control the flOw of blood through the passage, a suturing collar surrounding the outside portion of said base, said collar having external cover means including porous material for accommodating live heart tissue to form a union between the cover means and heart tissues, said cover means having an inner surface, annular continuous means located about and engaging an annular portion of the inner surface to hold the cover means in engagement with the outside portion of the base, and heat cured core plastic material surrounded by said cover means, said core plastic material having an outer surface bonded only to the inner surface of the cover means and the continuous means during the heat curing of the core plastic material.
Claim 3
Dependent Claim
42 words
