Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
168 words
A packaged catheter arrangement comprising a rubber catheter having an easily flexible insertion shaft, and a longitudinally extended tube sheath which is smoothly curvilinearly annular in cross section and formed of Elastic material and which is substantially longitudinally rigid relative to said flexible insertion shaft and thereby provides substantially self-sustained holding of its generally longitudinally extended tubular shape while said easily flexible shaft is disposed therewithin and is likewise similarly held in a longitudinally extended shape, said catheter having two divergent fluid passage arms connecting with said insertion shaft and having a divergent breadth substantially greater than the interior cross-section of said tube sheath, and extending freely from and beyond one end of said tube sheath for ease of grasping and removal of said catheter from said tube sheath, said insertion shaft being removably disposed along its length within said tube to a position closely adjacent the zone of connection of said divergent fluid passage arms with said insertion shaft, and being longitudinally generally rigidified by said tube.
Claim 2
Dependent Claim
168 words
A packaged catheter arrangement comprising a rubber catheter having an easily flexible insertion shaft, and a longitudinally extended tube sheath which is smoothly curvilinearly annular in cross section and formed of Elastic material and which is substantially longitudinally rigid relative to said flexible insertion shaft and thereby provides substantially self-sustained holding of its generally longitudinally extended tubular shape while said easily flexible shaft is disposed therewithin and is likewise similarly held in a longitudinally extended shape, said catheter having two divergent fluid passage arms connecting with said insertion shaft and having a divergent breadth substantially greater than the interior cross-section of said tube sheath, and extending freely from and beyond one end of said tube sheath for ease of grasping and removal of said catheter from said tube sheath, said insertion shaft being removably disposed along its length within said tube to a position closely adjacent the zone of connection of said divergent fluid passage arms with said insertion shaft, and being longitudinally generally rigidified by said tube.
Claim 3
Dependent Claim
16 words
A packaged catheter arrangement according to claim 1, said tube sheath being open at both ends.
Claim 4
Dependent Claim
20 words
A packaged catheter arrangement according to claim 2, said tube sheath being a smooth walled extrusion tube of plastic material.
Claim 5
Dependent Claim
51 words
A packaged catheter arrangement according to claim 1, said tube sheath being generally circular in cross-section, said tube sheath being elastically self-sustaining in its tubular form and longitudinally extended shape and being of sufficiently flexibly elastic material to enable finger pinching thereof to enable frictionally controlled withdrawal of said catheter therefrom.
Claim 6
Dependent Claim
34 words
A packaged catheter arrangement according to claim 1, and a flexible overpackage substantially more flexible than any flexing capability of said tube sheath, and surrounding said catheter and tube sheath and being closed therearound.
Claim 7
Dependent Claim
92 words
A packaged catheter arrangement according to claim 5, said flexible overpackage comprising a base of fibrous gas permeable 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 8
Dependent Claim
15 words
A packaged catheter arrangement according to claim 6, said sheets being peripherally heat seal bonded.
Claim 9
Dependent Claim
51 words
A packaged catheter arrangement according to claim 7, said tube sheath being a smooth walled extrusion tube of plastic material, said tube sheath being elastically self-sustaining in its tubular form and being of sufficiently flexibly elastic material to enable finger pinching thereof to enable fractionally controlled withdrawal of said catheter therefrom.
Claim 10
Dependent Claim
26 words
A packaged catheter arrangement according to claim 1, said catheter having a lubricating coating on said insertion shaft thereof and enclosed within said rigid tube sheath.
Claim 11
Dependent Claim
16 words
A packaged catheter arrangement according to claim 1, said tube sheath being generally circular in cross-section.
