Abstract
Abstract A wrapping system for an intra-aortic balloon in which a wrapping guide is provided which restrains the proximal end of the envelope from rotating as the distal end is rotated thereby providing a uniform wrap of the envelope from its distal to its proximal end. A wrapping wire is provided for rotating the envelope distal end and the wire extends through at least a part of the catheter to which the envelope is attached. A wrapping knob is coupled to the proximal end of the wrapping wire, whose distal end can be detachably coupled to the distal end of the envelope, and the knob is constructed to permit only a predetermined number of rotations in both wrapping and unwrapping the envelope.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
132 words
A wrapping system for an intra-aortic balloon comprising: a balloon assembly including a hollow catheter and an elongated envelope having its proximal end connected to said catheter, a member coupled to the distal end of said envelope and extending through it to support the envelope along its length, means coupled to the distal end of said envelope and extending through it to support the envelope along its length, means coupled to said distal end of said envelope for rotating said distal end, and a housing in which said envelope is located, said housing having means for restraining the proximal end of said envelope as the distal end is rotated to cause wrapping of the envelope relative to the catheter to proceed from the distal end of the envelope toward the proximal end.
Claim 2
Dependent Claim
132 words
A wrapping system for an intra-aortic balloon comprising: a balloon assembly including a hollow catheter and an elongated envelope having its proximal end connected to said catheter, a member coupled to the distal end of said envelope and extending through it to support the envelope along its length, means coupled to the distal end of said envelope and extending through it to support the envelope along its length, means coupled to said distal end of said envelope for rotating said distal end, and a housing in which said envelope is located, said housing having means for restraining the proximal end of said envelope as the distal end is rotated to cause wrapping of the envelope relative to the catheter to proceed from the distal end of the envelope toward the proximal end.
Claim 3
Dependent Claim
55 words
A system as in claim 1 wherein said housing comprises a package having front and rear sheets of material which are attached and between which said envelope is placed, and said restraining means comprising a portion of said sheets which are attached together in at least one area adjacent the proximal end of said envelope.
Claim 4
Dependent Claim
43 words
A system as in claim 1 whereas said housing comprises a package having front and rear sheets of material which are attached and between which said envelope is placed, and said restraining means comprising clip means on the outer surface of said sheets.
Claim 5
Dependent Claim
37 words
A system as in claim 1 wherein said housing comprises a tubular member in which said envelope is located, a portion of said tubular member being formed to engage and restrain the proximal portion of said envelope.
Claim 6
Dependent Claim
24 words
A system as in claim 4 wherein said portion of said housing has resilient walls which permit the wrapped balloon to be moved therethrough.
Claim 7
Dependent Claim
85 words
A system as in claim 1, wherein said support member comprises a lumen which extends the length of said envelope, said lumen having its distal end fastened to said envelope distal end and its proximal end extending within said catheter, a removable wrapping wire passing through said lumen and coupled to the distal end of said envelope for rotating it, withdrawal of said wire from said lumen providing a through passage from said lumen proximal end through the distal end and external of said envelope.
Claim 8
Dependent Claim
38 words
A system as in claim 6 further comprising a tip piece which forms a part of said wire coupling means to which the distal end of said lumen is attached, said tip piece also having a through passage.
Claim 9
Dependent Claim
49 words
A wrapping system as in claim 1 wherein said member for supporting said envelope is hollow and has its distal end attached to the distal end of said envelope, said means for rotating said distal end of said envelope comprising a wrapping wire extending within said hollow support member.
Claim 10
Dependent Claim
78 words
A system as in claim 8 further comprising means for rotating said wire comprising an inner housing, means coupling said inner housing to said proximal end of said wrapping wire, an outer housing rotatable relative to inner housing, a threaded member within said outer housing and fixed to rotate therewith, and a nut traveling on said threaded member as said outer housing is rotated and which is movable along said threaded member between said inner and outer housings.
Claim 11
Dependent Claim
31 words
A system as in claim 9 wherein the length of the threaded member determines the number of predetermined turns by the abutment of said nut with said inner and outer housings.
Claim 12
Dependent Claim
49 words
A wrapping system as in claim 8 wherein said envelope further comprises a tip piece attached to its distal end, the distal end of said hollow support member attached to said tip piece, and means for coupling the distal end of said wrapping wire to said envelope tip piece.
Claim 13
Dependent Claim
32 words
A system as in claim 11 wherein said means for coupling the distal end of said wrapping wire to said tip piece includes means for detachably coupling the wire to the tip.
Claim 14
Dependent Claim
33 words
A system as in claim 12 wherein said means for detachably coupling the distal end of said wrapping wire to said tip comprises mating key means formed on said tip and said wire.
Claim 15
Dependent Claim
36 words
A system as in claim 12 wherein said means for detachably coupling the distal end of said wrapping wire to said tip comprises a force fit between the distal end of said wire and said tip.
