Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
89 words
An apparatus for removing smoke from an operative site, comprising: (a) pump means for producing a source of vacuum pressure; (b) head means for distributing the vacuum pressure substantially around a perimeter of the operative site and including an open portion enscribed by said perimeter so as to be operative to permit a surgeon to perform a procedure within the perimeter; and (c) means for coupling the head pressure means to the pump means allowing the head means to remove smoke from about the perimeter of the operative site.
Claim 2
Independent Claim
89 words
An apparatus for removing smoke from an operative site, comprising: (a) pump means for producing a source of vacuum pressure; (b) head means for distributing the vacuum pressure substantially around a perimeter of the operative site and including an open portion enscribed by said perimeter so as to be operative to permit a surgeon to perform a procedure within the perimeter; and (c) means for coupling the head pressure means to the pump means allowing the head means to remove smoke from about the perimeter of the operative site.
Claim 3
Dependent Claim
16 words
