Abstract

1. A medical device with a proximal end for insertion into a body of a living being and an axially opposite distal end, the device comprising: a tip which in a first position forms the proximal end of the device, a drainage section forming a conduit extending in an axial direction of the device, and a retention section extending between the draining section and the tip, wherein the tip is operable between the first position and a second position so as to move the retention section between a first configuration and a second configuration, in which second configuration the retention section is expanded in a direction transverse to the axial direction. The conduit and the tip may be dimensioned to allow the tip to be received within the conduit. One advantage of such a system is that the retention system may be retracted entirely into the conduit so as to make insertion and retraction of the device more comfortable for the patient.

Claims

1. :

A medical device with a proximal end for insertion into a body of a living being and an axially opposite distal end, the device comprising;

a tip which in a first position forms the proximal end of the device,

a drainage section forming a conduit extending in an axial direction of the device, and

a retention section extending between the draining section and the tip,

wherein the tip is operable between the first position and a second position so as to move the retention section between a first configuration and a second configuration, in which second configuration the retention section is expanded in a direction transverse to the axial direction.

2. :

A medical device according to claim 1, wherein the conduit and the tip are dimensioned to allow the tip to be received within the conduit.

3. :

A medical device according to claim 1, further comprising a deployment member operable to move the tip between the first and second positions.

4. :

A medical device according to claim 1, wherein a first part of the retention section is located inside a second part of the retention section when the device is in the second configuration.

5. :

A medical device according to claim 1, wherein the retention section is movable to a third configuration wherein the retention section lies substantially within the drainage section.

6. :

A medical device according to claim 1, wherein the retention section comprises a braided portion with crossed filaments forming a braiding angle with said axial direction of the device.

7. :

A medical device according to claim 1, wherein the deployment member comprises a braided portion with crossed filaments forming a braiding angle with said axial direction of the device.

8. :

A medical device according to claim 6, wherein the filaments of the deployment member form an extension of the filaments of the retention section.

9. :

A medical device according to claim 1, wherein the drainage section comprises a braided portion with crossed filaments forming a braiding angle with said axial direction of the device.

10. :

A medical device according to claim 6, wherein the filaments of the drainage section form an extension of the filaments of the retention section.

11. :

A medical device according to claim 1, further comprising indicating means for indicating a position of the tip relative to the retention section or relative to the conduit.

12. :

A medical device according to claim 1, forming a catheter.

13. :

The use of a medical device according to claim 1 for increasing the comfort of a patient during insertion of the device.
