Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
62 words
A body implantable access device comprising; a hollow port, said port having an inlet an outlet and an infusion chamber therebetween, a self sealing septum disposed in and covering said inlet, and said self-sealing septum positioned on said port at substantially a right angle to said outlet such that a needle puncturing said septum will be substantially in line with said outlet.
Claim 2
Dependent Claim
62 words
A body implantable access device comprising; a hollow port, said port having an inlet an outlet and an infusion chamber therebetween, a self sealing septum disposed in and covering said inlet, and said self-sealing septum positioned on said port at substantially a right angle to said outlet such that a needle puncturing said septum will be substantially in line with said outlet.
Claim 3
Dependent Claim
44 words
The implantable device of claim 1 further comprising means to mount a catheter at said outlet and a flexible catheter mounted on said means to mount a catheter to provide fluid access to a portion of the body in which said device is implanted.
Claim 4
Dependent Claim
39 words
The implantable device of claim 2 wherein said means to mount a catheter comprises a hollow connector one end of which is inserted into said outlet of said port and the other end having annular barbs engaging said catheter.
Claim 5
Dependent Claim
27 words
The implantable device of claim 1 further comprising means to anchor said port subcutaneously at an angle substantially parallel with the skin line at the implantation site.
Claim 6
Dependent Claim
29 words
The implantable device of claim 4 wherein said means to anchor comprises first and second shoulder portions provided on said port, said shoulder portions extending circumferentially around said port.
Claim 7
Dependent Claim
21 words
The implantable device of claim 4 wherein said means to anchor comprises first and second circumferential recesses provided on said port.
Claim 8
Dependent Claim
33 words
The implantable device of claim 4 wherein said means to anchor comprises a tie-down member having means to mount said body, said tie-down member further including a flat portion defining a sutures area.
Claim 9
Dependent Claim
18 words
The implantable device of claim 7 wherein said flat portion includes a series of through-holes for passing sutures.
Claim 10
Dependent Claim
17 words
The implantable device of claim 7 wherein said flat area includes a fabric mesh for passing sutures.
Claim 11
Dependent Claim
23 words
The implantable device of claim 1 wherein said self sealing septum is angled at a shallow acute angle with respect to said outlet.
Claim 12
Dependent Claim
128 words
A body implantable device providing access to an internal portion of a living body for the administration and withdrawal of fluids comprising: a hollow port made of a biocompatible material, said port having wall portions defining an inlet, an outlet and an infusion chamber therebetween, a self sealing septum member positioned to cover said inlet at substantially a right angle to said outlet to provide a target for a needle used in the administration and withdrawal of fluids, said infusion chamber located upstream of said outlet and blocked from the inlet by said self-sealing septum, and said self sealing septum oriented in said inlet such that a needle passing through said system will stop in said infusion chamber area and will be substantially in line with said outlet.
Claim 13
Dependent Claim
128 words
A body implantable device providing access to an internal portion of a living body for the administration and withdrawal of fluids comprising: a hollow port made of a biocompatible material, said port having wall portions defining an inlet, an outlet and an infusion chamber therebetween, a self sealing septum member positioned to cover said inlet at substantially a right angle to said outlet to provide a target for a needle used in the administration and withdrawal of fluids, said infusion chamber located upstream of said outlet and blocked from the inlet by said self-sealing septum, and said self sealing septum oriented in said inlet such that a needle passing through said system will stop in said infusion chamber area and will be substantially in line with said outlet.
Claim 14
Dependent Claim
44 words
The implantable device of claim 11 further comprising means to mount a catheter at said outlet and a flexible catheter mounted on said means to mount a catheter to provide fluid access to a portion of the body in which said device is implanted.
Claim 15
Dependent Claim
39 words
The implantable device of claim 12 wherein said means to mount a catheter comprises a hollow connector one end of which is inserted into said outlet of said port and the other end having annular barbs engaging said catheter.
Claim 16
Dependent Claim
27 words
The implantable device of claim 11 further comprising means to anchor said port subcutaneously at an angle substantially parallel with the skin line at the implantation site.
Claim 17
Dependent Claim
29 words
The implantable device of claim 14 wherein said means to anchor comprises first and second shoulder portions provided on said port, said shoulder portions extending circumferentially around said port.
Claim 18
Dependent Claim
21 words
The implantable device of claim 14 wherein said means to anchor comprises first and second circumferential recesses provided on said port.
Claim 19
Dependent Claim
