Surgical stapling system and method of applying staples from multiple staple cartridges
First Claim
1. A surgical staple cartridge comprisinga pair of generally coextensive cartridge bodies adapted to fit within opposed jaws of a surgical stapler;
- a hinge connecting said cartridge bodies;
a staple having ductile tissue penetrating legs, said staple being carried by a first of said cartridge bodies; and
means formed in a second of said cartridge bodies for receiving said tissue penetrating legs of said staple when said staple is driven through anatomical tissue.

Abstract
A surgical stapling system includes a staple cartridge having a pair of generally coextensive cartridge bodies adapted to fit within opposed jaws of a stapling instrument and one or more staples carried by a first of the cartridge bodies in opposed relation to apertures or anvils formed in a second of the cartridge bodies. The cartridge bodies are preferably and advantageously made of bioabsorbable materials so that they can be left in place within the body and so that another staple cartridge can be advanced between the opposed jaws of the stapling instrument without the need of having to withdraw the stapling instrument from the body.

16. A surgical stapler comprising
a housing; -
an elongate tubular body with a proximal end mounted by said housing and a distal end including a pair of opposed jaws; a plurality of staple cartridges disposed within said elongate tubular body, said staple cartridges each carrying at least one staple having a plurality of tissue penetrating legs; said opposed jaws having a staple cartridge receiving position defining a space between said opposed jaws for receiving a staple cartridge; and an advancing mechanism carried by said housing and including a member movable distally to advance a distalmost staple cartridge into said space between said opposed jaws. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A surgical stapler comprising
a housing; -
an outer tubular member having a proximal end mounted by said housing and terminating distally at a distal end; an intermediate member having a tubular body disposed telescopically within said outer tubular member, a proximal end mounted by said housing and a distal end including a pair of opposed jaws resiliently biased apart; a staple cartridge disposed within said opposed jaws, said staple cartridge carrying at least one staple having a plurality of tissue penetrating legs; and a handle coupled with at least one of said intermediate and outer tubular members to create relative movement between said intermediate and outer tubular members, whereby said pair of opposed jaws is closed around said staple cartridge when said distal end of said outer tubular member is advanced over said jaws and said tissue penetrating legs are driven through anatomical tissue held between said jaws.

an outer tubular member having a proximal end mounted by said housing and terminating distally at a distal end; an intermediate member having a tubular body disposed telescopically within said outer tubular member, a proximal end mounted by said housing and a distal end including a pair of opposed jaws resiliently biased apart; an inner tubular member removably disposed at least partly within said intermediate member and carrying a plurality of staple cartridges; an advancing mechanism including a member movable to advance at least one of said staple cartridges between said opposed jaws of said intermediate member; and a handle coupled with at least one of said intermediate and outer tubular members to create relative movement between said intermediate and outer tubular members, whereby said pair of opposed jaws is closed around said at least one staple cartridge when said distal end of said outer tubular member is advanced distally over said jaws. - View Dependent Claims (27, 28, 29, 30, 31)

32. A method of stapling anatomical tissue comprising the steps of
positioning the anatomical tissue between generally opposed, hingedly connected cartridge bodies of a staple cartridge; -
compressing the staple cartridge around the anatomical tissue; penetrating through the anatomical tissue with ductile tissue penetrating legs carried by a first of the cartridge bodies; receiving the tissue penetrating legs in spaces defined by a second of the cartridge bodies; and bending the tissue penetrating legs to constrict the anatomical tissue. - View Dependent Claims (33, 34, 35, 36)

37. A surgical staple cartridge comprising
a pair of generally coextensive cartridge bodies adapted to fit within opposed jaws of a surgical stapler; -
a staple having ductile tissue penetrating legs, said staple being carried by a first of said cartridge bodies; and a plurality of apertures formed in a second of said cartridge bodies in opposed relation to said tissue penetrating legs of said staple, said apertures receiving said tissue penetrating legs of said staple when said staple is driven through anatomical tissue positioned between said cartridge bodies. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45)

46. A method of stapling anatomical tissue comprising the steps of
positioning the anatomical tissue between generally opposed cartridge bodies of a staple cartridge; -
compressing the staple cartridge around the anatomical tissue; penetrating through the anatomical tissue with ductile tissue penetrating legs carried by a first of the cartridge bodies; passing ends of the tissue penetrating legs through openings in the second cartridge body until the tissue penetrating legs protrude from the openings; and bending the protruding ends of the tissue penetrating legs against an outer surface of the second cartridge body to constrict the anatomical tissue. - View Dependent Claims (47, 48)
