Abstract
Abstract A packaged catheter arrangement having a soft and pliable latex rubber catheter for body orifice use and having its shaft slidably removably disposed within a relatively rigid tube sheath of plastic to form a catheter handling assembly which is enclosed as a unit within a peripherally sealed peel-apart dual sheet overpackage. The tube sheath is sealed closed at one end and the catheter preferably has a pre-lubrication coating on its insertion shaft and enclosed within the closed-ended tube sheath.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
A packaged catheter arrangement, comprising a flexible rubber catheter having an easily flexible insertion shaft with an insertion tip at one end and having two divergent fluid passage arms, a flexible tube sheath, the tubular extent and shape of said tube sheath laterally enveloping and serving to protect the length of said catheter insertion shaft during and subsequent to assembly as a dual component unit of said packaged catheter arrangement, said tube sheath being closed at one end and open at its other end, the interior of said tube sheath being of a size to accommodate said catheter shaft, but insufficient to accommodate said two divergent fluid passage arms, and said catheter insertion shaft being removably disposed within said tube sheath with its insertion tip adjacent said closed end of said tube sheath and having its two divergent fluid passage arms adjacent and extending beyond said open end of said tube sheath.
Claim 2
Dependent Claim
152 words
A packaged catheter arrangement, comprising a flexible rubber catheter having an easily flexible insertion shaft with an insertion tip at one end and having two divergent fluid passage arms, a flexible tube sheath, the tubular extent and shape of said tube sheath laterally enveloping and serving to protect the length of said catheter insertion shaft during and subsequent to assembly as a dual component unit of said packaged catheter arrangement, said tube sheath being closed at one end and open at its other end, the interior of said tube sheath being of a size to accommodate said catheter shaft, but insufficient to accommodate said two divergent fluid passage arms, and said catheter insertion shaft being removably disposed within said tube sheath with its insertion tip adjacent said closed end of said tube sheath and having its two divergent fluid passage arms adjacent and extending beyond said open end of said tube sheath.
Claim 3
Dependent Claim
31 words
A packaged catheter arrangement according to claim 1, one of said divergent fluid passage arms being an inflation arm disposed adjacent and extending beyond said open end of said tube sheath.
Claim 4
Dependent Claim
24 words
A packaged catheter arrangement according to claim 1, said closed other end of said tube sheath having a heat seal crimp extending transversely thereof.
Claim 5
Dependent Claim
29 words
A packaged catheter arrangement according to claim 1, said catheter insertion shaft being coated with a lubricating medium, and said coated insertion shaft being enclosed within said tube sheath.
Claim 6
Dependent Claim
21 words
A packaged catheter arrangement according to claim 1, said catheter having a further fluid conducting arm extending beyond said tube sheath.
Claim 7
Dependent Claim
23 words
a packaged catheter arrangement according to claim 1, and a flexible overpackage surrounding said entire catheter and tube sheath and being closed therearound.
Claim 8
Dependent Claim
90 words
A packaged catheter arrangement according to claim 6, said flexible overpackage comprising a base of fibrous sheet material and a cover sheet of light-transmitting see-through plastic peripherally bonded to said base sheet about said catheter and tube sheath to form an enclosed loose pocket or cavity for said catheter and tube sheath, said cover sheet being removably peelably separable from said base sheet, and said sheets having unbonded tab ends at one end of said overpackage for ease in separating said sheets to remove said catheter and tube sheath therefrom.
Claim 9
Dependent Claim
16 words
a packaged catheter arrangement according to claim 7, said sheets having a peripheral heat seal bond.
Claim 10
Dependent Claim
57 words
A packaged catheter arrangement according to claim 1, said flexible tube sheath being substantially more rigid than said catheter insertion shaft and serving the dual function of protecting and rigidifying the length of said insertion shaft and presenting said two divergent passage arms in open accessible extended relation beyond the adjacent open end of said tube sheath.
