Abstract
Abstract A locking catheter system including a flexible catheter having a restraining portion such as a pigtail, malecot rib or J-curve at its distal end and a flexible filament extending therefrom to attaching means at the other end of the catheter. The attaching means comprise a self-sealing sleeve through which the filament passes and an elastomeric sheath which encapsulates the sleeve to restrain the filament.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
113 words
A locking catheter system comprising: a flexible catheter having a restraining portion at its distal end; means, extending from the restraining portion to the proximal end of the catheter, for drawing the restraining portion toward the proximal end; and means, at the proximal end of the catheter, for removably attaching the drawing means to the catheter, said attaching means comprising a self-sealing sleeve covering a portion of the proximal end of the catheter and an elastomeric sheath sized to fit over the self-sealing sleeve, a portion of said drawing means for positioning along the self-sealing sleeve, said portion of said drawing means restrained when the elastomeric sheath is drawn over the self-sealing sleeve.
Claim 2
Dependent Claim
113 words
A locking catheter system comprising: a flexible catheter having a restraining portion at its distal end; means, extending from the restraining portion to the proximal end of the catheter, for drawing the restraining portion toward the proximal end; and means, at the proximal end of the catheter, for removably attaching the drawing means to the catheter, said attaching means comprising a self-sealing sleeve covering a portion of the proximal end of the catheter and an elastomeric sheath sized to fit over the self-sealing sleeve, a portion of said drawing means for positioning along the self-sealing sleeve, said portion of said drawing means restrained when the elastomeric sheath is drawn over the self-sealing sleeve.
Claim 3
Dependent Claim
22 words
The locking catheter of claim 1 in which the restraining means is a preformed curve in the distal end of the catheter.
Claim 4
Dependent Claim
16 words
The locking catheter of claim 2 in which the preformed curve is in a pigtail shape.
Claim 5
Dependent Claim
15 words
The locking catheter of claim 2 in which the preformed curve is a malecot rib.
Claim 6
Dependent Claim
16 words
The locking catheter system of claim 1 in which the drawing means is a flexible filament.
Claim 7
Dependent Claim
16 words
The locking catheter system of claim 5 in which the flexible filament is non-woven and non-porous.
Claim 8
Dependent Claim
37 words
The locking catheter system of claim 1 wherein the drawing means comprises a flexible filament positioned, in part, within the distal end of the flexible catheter to emerge from the proximal end thereof, below the self-sealing sleeve.
Claim 9
Dependent Claim
77 words
The locking catheter system of claim 1 in which the drawing means comprises a flexible filament which is fixed to the proximal end of the catheter, passing therefrom through the interior of the catheter to emerge through a hole near the distal end of the catheter, whereupon it re-enters the interior of the catheter through another, distally located opening and passes through the interior of the catheter to emerge through a suture exit in the self-sealing sleeve.
Claim 10
Dependent Claim
23 words
The locking catheter of claim 8 wherein the latex sleeve seals along the outer surface of the drawing means where it passes therethrough.
Claim 11
Dependent Claim
15 words
The locking catheter of claim 1 in which the self-sealing sleeve is made of latex.
Claim 12
Dependent Claim
15 words
The locking catheter of claim 1 in which the elastomeric sheath is made of silicone.
Claim 13
Dependent Claim
16 words
The locking catheter system of claim 1 in which the elastomeric sheath encapsulates the self-sealing sleeve.
Claim 14
Dependent Claim
47 words
The locking catheter of claim 12 in which the elastomeric sheath is adapted to be rolled up into an annular ring at the distal end of the self-sealing sleeve when in an unrestraining closed position and rolled out over the self-sealing sleeve when in a restraining position.
Claim 15
Dependent Claim
20 words
The locking catheter of claim 1 in which the elastomeric sheath includes an integral annular portion at its proximal end.
Claim 16
Dependent Claim
109 words
A locking catheter system comprising: a flexible catheter having a restraining portion at its distal end; a flexible filament, extending from the restraining portion to the proximal end of the catheter, for drawing the restraining portion toward the proximal end; and means, at the proximal end of the catheter, for removably attaching the flexible filament; said attaching means comprising a self-sealing latex sleeve for covering a portion of the proximal end of the catheter and a silicone sheath sized to fit over the latex sleeve, a portion of the flexible filament positioned along the latex sleeve and held in place by drawing the silicone sheath over the latex sleeve.
Claim 17
Dependent Claim
109 words
A locking catheter system comprising: a flexible catheter having a restraining portion at its distal end; a flexible filament, extending from the restraining portion to the proximal end of the catheter, for drawing the restraining portion toward the proximal end; and means, at the proximal end of the catheter, for removably attaching the flexible filament; said attaching means comprising a self-sealing latex sleeve for covering a portion of the proximal end of the catheter and a silicone sheath sized to fit over the latex sleeve, a portion of the flexible filament positioned along the latex sleeve and held in place by drawing the silicone sheath over the latex sleeve.
Claim 18
Dependent Claim
19 words
The locking catheter of claim 15 in which the curved portion is in the shape of a malecot rib.
Claim 19
Dependent Claim
18 words
The locking catheter of claim 15 in which the curved portion is in the shape of a J-curve.
Claim 20
Dependent Claim
29 words
The locking catheter system of claim 15 in which the drawing means is attached to the proximal end of the catheter by molding, gluing, welding or other suitable means.
Claim 21
Dependent Claim
28 words
The locking catheter system of claim 15 in which the silicone sheath includes an integral preformed annular silicon ring, attached to the silicon sheath at its proximal end.
