Abstract

A catheter assembly ( 1 ) includes an inner member ( 12 ) having a proximal end ( 15 ), a distal end ( 13 ), and a lumen configured to store a hydrating fluid ( 28 ) An outer member ( 10 ) has a proximal end ( 19 ), a distal end ( 16 ), and a lumen configured to receive therein a portion of the inner member ( 12 ) The outer member ( 10 ) is movable relative to the inner member ( 12 ) at least one of, between a first position (FIG. 1 ) preventing fluid ( 28 ) from passing out of the at least one drainage opening ( 14 ) from within the lumen of the inner member ( 12 ) and a second position (FIG. 2 ) allowing fluid ( 28 ) to pass out of the at least one drainage opening ( 14 ) from within the lumen of the inner member ( 12 ).

First claim

What is claimed is:

1. A catheter assembly comprising:
an inner member having a proximal end, a distal end, and a lumen;
a hydrating fluid stored in the inner member lumen in a first catheter assembly position; and
an outer member designed for insertion into a urethra of a patient surrounding the inner member in the first catheter assembly position, the outer member having a proximal end, a distal end, a lumen, and at least one drainage opening, wherein the outer member is movable relative to the inner member between the first catheter assembly position preventing fluid from passing out of the at least one drainage opening from within the lumen of the inner member and a second catheter assembly position allowing fluid to pass out of the at least one drainage opening.

2. The catheter assembly of claim 1 , wherein, in the first catheter assembly position, the outer member covers an entire visible portion of the inner member.

3. The catheter assembly of claim 1 , wherein, in the second catheter assembly position, the distal end of the outer member extends past the distal end of the inner member by an amount greater than about 25% of an overall length of the outer member.

4. The catheter assembly of claim 1 , wherein, in the second catheter assembly position, the distal end of the outer member extends past the distal end of the inner member by an amount greater than about 50% of an overall length of the outer member.

5. The catheter assembly of claim 1 , wherein, in the second catheter assembly position, the distal end of the outer member extends past the distal end of the inner member by an amount equal to between about 50% and 90% of an overall length of the outer member.

6. The catheter assembly of claim 1 , wherein the outer member further comprises a coating arranged on an outer surface including at least one of:
a hydrateable coating;
a lubricious antimicrobial coating; and
a hydrophilic biocompatible coating.

7. The catheter assembly of claim 1 , wherein the at least one drainage opening comprises one of:
at least two staggered openings;
at least two generally oval-shaped openings;
and
between 2 and 6 openings.

8. The catheter assembly of claim 1 , wherein the inner member comprises a lubricious antimicrobial coating arranged at least on an outer surface of the distal end of the inner member.

9. The catheter assembly of claim 1 , wherein the outer member comprises a generally rounded and/or atraumatic closed distal tip and further comprising a plug arranged on a proximal end of the catheter assembly.

10. The catheter assembly of claim 1 , wherein the outer member is telescopically movable and lockable in the second catheter assembly position.

11. The catheter assembly of claim 1 , wherein the outer member is releasably retainable in the second catheter assembly position via a threaded engagement.

12. The catheter assembly of claim 1 , wherein the outer member is releasably retainable in the second catheter assembly position via engagement between at least one locking projection and at least one locking recess.

13. The catheter assembly of claim 1 , further comprising at least one of:
a flexible container arranged to substantially contain therein the outer member and the inner member;
a flexible container sized to accommodate movement of the outer member relative to the inner member between the first and second catheter assembly positions;
a flexible container comprising an expandable section; and
a removably securable flexible container or pouch.

14. The catheter assembly of claim 1 , wherein the outer member includes a hydrophillic coating, and wherein when the outer member is in the second catheter assembly position, the hydrating fluid is allowed to pass out of the at least one drainage opening to contact the hydrophillic coating and form a lubricating coating on the outer member.
