Abstract
Abstract A percutaneous catheter introducer having a tube with tube handle, a seal housing containing a seal, and a needle with a needle handle. The needle is extended through the seal housing and tube. The needle and tube are percutaneously inserted into an anatomical body cavity. The needle is removed and a catheter is inserted. The seal housing can be removed in order to use the tube for aspiration. Alternatively, the seal is positioned within the tube handle.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
117 words
A percutaneous catheter introducer, comprising: a tube defining a lumen for guiding a catheter therethrough and having a proximal end, said tube being percutaneously insertable into an anatomical body cavity for guiding a catheter thereinto; a needle extendable through said lumen, said needle having a proximal end; a seal housing connected to said proximal end of said tube; and a seal positioned within said seal housing, said seal substantially sealing said tube against leakage out of said proximal end of said tube as said needle is extended through said seal and after said needle is removed from said seal, said seal housing being detachable from said tube so as to selectively permit fluid communication through said tube.
Claim 2
Dependent Claim
117 words
A percutaneous catheter introducer, comprising: a tube defining a lumen for guiding a catheter therethrough and having a proximal end, said tube being percutaneously insertable into an anatomical body cavity for guiding a catheter thereinto; a needle extendable through said lumen, said needle having a proximal end; a seal housing connected to said proximal end of said tube; and a seal positioned within said seal housing, said seal substantially sealing said tube against leakage out of said proximal end of said tube as said needle is extended through said seal and after said needle is removed from said seal, said seal housing being detachable from said tube so as to selectively permit fluid communication through said tube.
Claim 3
Dependent Claim
37 words
A percutaneous catheter introducer in accordance with claim 1 wherein said seal permits penetration of said needle so as to make a relatively small aperture therein, said aperture being substantially closed as said needle is removed therefrom.
Claim 4
Dependent Claim
18 words
A percutaneous catheter introducer in accordance with claim 2 wherein said aperture permits insertion of a catheter therethrough.
Claim 5
Dependent Claim
43 words
A percutaneous catheter introducer in accordance with claim 3 wherein said seal substantially seals said tube against leakage out of said proximal end of said tube as a catheter is extended through said seal and after said catheter is removed from said seal.
Claim 6
Dependent Claim
22 words
A percutaneous catheter introducer in accordance with claim 1 wherein said seal defines a central aperture and plurality of radially extending slits.
Claim 7
Dependent Claim
19 words
A percutaneous catheter introducer in accordance with claim 5 wherein said central aperture permits insertion of a catheter therethrough,
Claim 8
Dependent Claim
24 words
A percutaneous catheter introducer in accordance with claim 6 wherein said central aperture and slits permit aspiration from said proximal end of said tube.
Claim 9
Dependent Claim
18 words
A percutaneous catheter introducer in accordance with claim 5 wherein said seal includes at least one reinforcing rib.
Claim 10
Dependent Claim

A percutaneous catheter introducer in accordance with claim 13 wherein said anchor is adjustable between an anchored configuration and a non-anchored configuration, said anchor being affixed to said tube when in said anchored configuration and being longitudinally slidable along the length of said tube when in said non-anchored configuration.
Claim 16
Dependent Claim
20 words
A percutaneous catheter introducer in accordance with claim 14 wherein said anchor includes a plurality of feet extending radially outward.
Claim 17
Dependent Claim
