Abstract
Abstract A peelable sheath includes a sheath formed of a flexible tube having a pair of separation lines arranged longitudinally on radially opposite sides of the tube to form a pair of peelable sheath portions, and a hub connector bonded to the proximal end of the sheath. A pair of wings are bonded to the proximal end of the sheath to faciliate separation. The hub connector and sheath are bonded by a web extending axially from a shoulder of the hub connector and including a pair of web tabs arranged on radially opposite sides of the hub connector. The web tabs are bonded to the sheath across respective separation lines, thereby preventing premature separation of the peelable sheath portions. The web also includes a pair of web support struts, arranged on radially opposite sides of the hub and rotated about 90° relative to the web tabs, that are bonded to the respective wings to prevent premature separation of the hub connector from the sheath.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
68 words
A peelable sheath, comprising: a flexible tube having separation means for dividing said tube into a pair of peelable sheath portions; a hub attached to a proximal end of said tube, said hub being bonded to said tube by an annular web, and being separable from said tube by bending or twisting said hub relative to said sheath; and connecting means for connecting said tube to another device.
Claim 2
Dependent Claim
68 words
A peelable sheath, comprising: a flexible tube having separation means for dividing said tube into a pair of peelable sheath portions; a hub attached to a proximal end of said tube, said hub being bonded to said tube by an annular web, and being separable from said tube by bending or twisting said hub relative to said sheath; and connecting means for connecting said tube to another device.
Claim 3
Dependent Claim
45 words
The peelable sheath of claim 1, further comprising a pair of wing members disposed at the proximal end of said tube and bonded, respectively, to said pair of peelable sheath portions, wherein said sheath portions can be peeled apart by pulling said wing members apart.
Claim 4
Dependent Claim
16 words
The peelable sheath of claim 2, wherein said hub also is bonded to said wing members.
Claim 5
Dependent Claim
21 words
The peelable sheath of claim 2, wherein said hub is connected to said sheath and wing members through said annular web.
Claim 6
Dependent Claim
14 words
The peelable sheath of claim 2, wherein said wing members are composed of polyethylene.
Claim 7
Dependent Claim
31 words
The sheath of claim 1, wherein said separation means are in a form selected from the group comprising fold lines, score lines, perforations, indentations, thinned wall portions, and integral cutting elements.
Claim 8
Dependent Claim
12 words
The sheath of claim 1, wherein said hub comprises a luer fitting.
Claim 9
Dependent Claim
14 words
The sheath of claim 7, wherein said luer fitting comprises a threaded body portion.
Claim 10
Dependent Claim
14 words
The peelable sheath of claim 1, wherein said flexible tube is composed of polyethylene.
Claim 11
Dependent Claim
13 words
The peelable sheath of claim 1, wherein said hub is composed of polyethylene.

A peelable sheath, comprising: a flexible tube having separation means for dividing said tube into peelable sheath portions; a fluid-tight hub attached to a proximal end of said tube; and means for connecting said tube to another device.
Claim 16
Dependent Claim
38 words
A peelable sheath, comprising: a flexible tube having separation means for dividing said tube into peelable sheath portions; a fluid-tight hub attached to a proximal end of said tube; and means for connecting said tube to another device.
Claim 17
Dependent Claim
65 words
A peelable sheath, comprising: a flexible tube having separation means for dividing said tube into a plurality of peelable sheath portions; a hub attached to a proximal end of said tube, said hub being fluid tightly bonded to said tube, and separable from said tube by bending or twisting said hub relative to said sheath; and connecting means for connecting said tube to another device.
