Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
134 words
A kit assembly for use during a laparoscopic surgery comprising: a first trocar for use with a cannula to insert the cannula into the abdominal cavity of a patient, said trocar having a first obturator; a second trocar for use with a cannula to insert the cannula into the abdominal cavity of a patient, said second trocar having a second obturator, said first trocar being of a different type of trocar than said second trocar; a package for enclosing said first and second trocars, wherein said first obturator has sharp cutting surfaces and said first trocar has a means for protecting underlying organs from the sharp obturator surfaces, and said second obturator has sharp cutting surfaces and said second trocar is free of a means for protecting underlying organs from the sharp cutting surfaces.
Claim 2
Dependent Claim
134 words
A kit assembly for use during a laparoscopic surgery comprising: a first trocar for use with a cannula to insert the cannula into the abdominal cavity of a patient, said trocar having a first obturator; a second trocar for use with a cannula to insert the cannula into the abdominal cavity of a patient, said second trocar having a second obturator, said first trocar being of a different type of trocar than said second trocar; a package for enclosing said first and second trocars, wherein said first obturator has sharp cutting surfaces and said first trocar has a means for protecting underlying organs from the sharp obturator surfaces, and said second obturator has sharp cutting surfaces and said second trocar is free of a means for protecting underlying organs from the sharp cutting surfaces.
Claim 3
Dependent Claim
15 words
A kit assembly according to claim 1 wherein the second trocar comprises a disposable trocar.
Claim 4
Dependent Claim
33 words
A kit assembly according to claim 1 wherein said first and second trocar have distal ends, and the outer diameter of the first and second trocars at their distal ends are substantially identical.
Claim 5
Dependent Claim
28 words
A kit assembly according to claim 1 wherein one of said first or second trocars comprises a reusable trocar capable of being sterilized and used on different patients.
Claim 6
Dependent Claim
22 words
A kit assembly according to claim 1 wherein one of said first and second trocars comprises a trocar with a disposable obturator.
Claim 7
Dependent Claim
173 words
A kit assembly for use during a laparoscopic surgery comprising: a first cannula adapted to be inserted into the abdominal cavity of a patient by use of a trocar, said first cannula having an access tube with a lumen having a first inner diameter; a second cannula adapted to be inserted into the abdominal cavity of a patient by use of a trocar, said second cannula having an access tube with a lumen having a second inner diameter substantially the same as the first inner diameter; a package for enclosing said first and second cannulae wherein said first cannula is of a different type than said second cannula, wherein said first cannula has a means for restricting loss of insufflating gas from the abdominal cavity and a means for affording replenishment of the insufflating gas within the abdominal cavity; and said second cannula is free of a means for restricting loss of insufflating gas from the abdominal cavity and of a means for affording replenishment of the insufflating gas within the abdominal cavity.
Claim 8
Dependent Claim
173 words
A kit assembly for use during a laparoscopic surgery comprising: a first cannula adapted to be inserted into the abdominal cavity of a patient by use of a trocar, said first cannula having an access tube with a lumen having a first inner diameter; a second cannula adapted to be inserted into the abdominal cavity of a patient by use of a trocar, said second cannula having an access tube with a lumen having a second inner diameter substantially the same as the first inner diameter; a package for enclosing said first and second cannulae wherein said first cannula is of a different type than said second cannula, wherein said first cannula has a means for restricting loss of insufflating gas from the abdominal cavity and a means for affording replenishment of the insufflating gas within the abdominal cavity; and said second cannula is free of a means for restricting loss of insufflating gas from the abdominal cavity and of a means for affording replenishment of the insufflating gas within the abdominal cavity.
Claim 9
Dependent Claim
17 words
