Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises a loop formed on said first portion of said retrieval member extending beyond an end of said cylindrical member to prevent passage of said first portion through said cylindrical member.
Claim 2
Dependent Claim
167 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises a loop formed on said first portion of said retrieval member extending beyond an end of said cylindrical member to prevent passage of said first portion through said cylindrical member.
Claim 3
Dependent Claim
145 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises an elongated, annular member having a bore therethrough.
Claim 4
Dependent Claim
145 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises an elongated, annular member having a bore therethrough.
Claim 5
Dependent Claim
162 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises at least two elongated, solid members, each solid member terminating in an enlarged end having a greater diameter than said bore of said cylindrical member.
Claim 6
Dependent Claim
162 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises at least two elongated, solid members, each solid member terminating in an enlarged end having a greater diameter than said bore of said cylindrical member.
Claim 7
Dependent Claim
172 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises at least two elongated, solid members, each solid member terminating in a single common enlarged end to both said members, said common enlarged end having a greater diameter than said bore of said cylindrical member.
Claim 8
Dependent Claim
172 words
A safety catheter facilitating the flow of fluids to and from a body and the safe removal of said catheter from said body, said safety catheter comprising: an elongated cylindrical member having a bore therethrough; and at least one retrieval member extending throughout said bore and extending from each end of said cylindrical member, a first portion of said retrieval member extending beyond an end of said cylindrical member terminating in an end having a greater diameter than said bore of said cylindrical member to prevent said end from entering said bore of said cylindrical member wherein said retrieval member maintains said bore of said cylindrical member open to allow said flow of said fluids to and from said body and the safe retrieval of said cylindrical member from said body and wherein said retrieval member comprises at least two elongated, solid members, each solid member terminating in a single common enlarged end to both said members, said common enlarged end having a greater diameter than said bore of said cylindrical member.
Claim 9
Dependent Claim
