Abstract
Abstract A device for holding, in a longitudinally extended state, a catheter e.g. of the Malecot or Pezzer type, having an open proximal end, a closed distal end and an elastic bulge adjacent the distal end. The device comprises a mandrel which is insertable into the catheter to move the distal end of the catheter away from the proximal end and a bearing component for the mandrel having at least one latching member mounted thereon which is releasably connectable to the proximal end of the catheter to hold the mandrel in the catheter when the latter is in its extended position. An assembly is also described in which the bearing component is permanently secured to the proximal end of the catheter, the bearing component having a seat in which the proximal end of the mandrel can be releasably inserted.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
A device for holding, in a longitudinally extended state, a catheter having an open proximal end, a closed distal end and an elastic bulge adjacent the distal end, the said device comprising a mandrel having a distal end and a proximal end insertable into the catheter, to move the distal end of the catheter away from its proximal end, a bearing component for the mandrel connected to the proximal end of the mandrel and at least one latching member mounted on the bearing component and releasably connectable to the proximal end of the catheter.
Claim 2
Independent Claim
94 words
A device for holding, in a longitudinally extended state, a catheter having an open proximal end, a closed distal end and an elastic bulge adjacent the distal end, the said device comprising a mandrel having a distal end and a proximal end insertable into the catheter, to move the distal end of the catheter away from its proximal end, a bearing component for the mandrel connected to the proximal end of the mandrel and at least one latching member mounted on the bearing component and releasably connectable to the proximal end of the catheter.
Claim 3
Dependent Claim
32 words
A device as claimed in claim 1, and further comprising locking jaws on the latching member for gripping the proximal end of the catheter when the latter is in its stretched condition.
Claim 4
Dependent Claim
24 words
A device as claimed in claim 1, wherein the latching member is pivotally mounted on the bearing component in the manner of a lever.
Claim 5
Dependent Claim
38 words
A device as claimed in claim 3, wherein the bearing component includes a central member and two parallel latching members extending therefrom and carrying at their free ends locking jaws for gripping the proximal end of the catheter.
Claim 6
Dependent Claim
24 words
A device as claimed in claim 4, wherein the bearing component is placed centrally of the two parallel arms to provide an H-shaped configuration.
Claim 7
Dependent Claim
36 words
A device as claimed in claim 4, wherein the bearing component is arranged at the remote end of the latching members from the jaws and further comprising an element intermediate the bearing component and the jaws.
Claim 8
Dependent Claim
17 words
A device as claimed in claim 6, wherein the element is slidable parallel to the latching members.
Claim 9
Dependent Claim
20 words
A device as claimed in claim 3, wherein the latching member is controllable by pressure exerted perpendicularly to its length.
Claim 10
Dependent Claim
17 words
A device as claimed in claim 1, wherein the bearing component is firmly fixed to the mandrel.
Claim 11
Dependent Claim
85 words
A catheter assembly comprising a catheter having an open proximal end, a closed distal end and an elastic bulge adjacent the distal end, a bearing component including an arm connected to the proximal end of the catheter, a mandrel having a distal end and a proximal end insertable into the catheter to move the distal end of the catheter away from its proximal end and a seat on the bearing component for releasable insertion of the proximal end of the mandrel into the bearing component.
Claim 12
Dependent Claim
85 words
A catheter assembly comprising a catheter having an open proximal end, a closed distal end and an elastic bulge adjacent the distal end, a bearing component including an arm connected to the proximal end of the catheter, a mandrel having a distal end and a proximal end insertable into the catheter to move the distal end of the catheter away from its proximal end and a seat on the bearing component for releasable insertion of the proximal end of the mandrel into the bearing component.
Claim 13
Dependent Claim
17 words
An assembly as claimed in claim 10, and further comprising a frame firmly fixed to the arm.
Claim 14
Dependent Claim
36 words
An assembly as claimed in claim 10, wherein the bearing component is connected by two arms to the proximal end of the catheter and the arms are pivotally mounted on the proximal end of the catheter.
Claim 15
Dependent Claim
48 words
An assembly as claimed in claim 10, and comprising two arms, one permanently connected to the proximal end of the catheter and the other free, and further comprising a lug on the proximal end of the catheter and an orifice in said other arm securable over said lug.
Claim 16
Dependent Claim
16 words
An assembly as claimed in claim 10, wherein the assembly is constructed of a silicone elastomer.
Claim 17
Dependent Claim
16 words
An assembly as claimed in claim 10, wherein the assembly is constructed of a thermoplastic material.
