Abstract

Disclosed is a hub for a transluminal sheath. The hub provides a handle for grasping the sheath, provides connections for fluid inlet and outlet lines, and provides for attaching mechanisms between the sheath and a dilator. The hub can be used on a non-radially expandable sheath, or it can be used on a sheath having a radially expandable configuration. In an exemplary application, the hub is fitted to a sheath, which provides access for a diagnostic or therapeutic procedure such as ureteroscopy or stone removal.

Claims

1. A transluminal access sheath for insertion into a urethra by a person having a pair of adjacent fingers, the access sheath comprising:

an elongate tube having a lumen extending between a proximal end and a distal end, the elongate tube having a distal portion and a proximal portion;

a removable inner member disposed within the lumen of the elongate tube;

a hub coupled to the proximal end of the elongate tube, the hub comprising a distally facing surface and a proximally facing surface, the distally facing surface forming at least in part a straight cone, sized and configured to receive adjacent fingers of the user, the proximally facing surface forming a straight taper configured to funnel instrumentation into the lumen.

2. The transluminal sheath of claim 1 wherein the sheath hub is configured at its distal end to slip into the urethra and to allow the proximal end of the sheath tube to slip into the urethra.

3. The transluminal sheath of claim 1 wherein the sheath hub is configured with a substantially linear outline when viewed in axial cross-section.

4. The transluminal sheath of claim 1 wherein the sheath hub has a diameter that is less than ½

the diameter of an average adult finger, the shape of the distally facing side of the hub is not curved to a radius substantially the same as a finger, and wherein the hub is not receivable by adjacent fingers.

5. The transluminal sheath of claim 1, wherein the distal portion of the elongate tube is expandable from a first, smaller diameter to a second, greater diameter.

6. The transluminal sheath of claim 5, wherein the proximal portion of the elongate tube is substantially non-expandable and which is affixed at its distal end to a proximal end of the expandable distal portion.

7. The transluminal sheath of claim 6, wherein the inner member comprise a dilator that can be used to expand the distal portion of the access sheath

8. The transluminal sheath of claim 1 wherein the proximally facing side of the sheath hub is releasably affixed to an inner member hub, which covers the proximally facing side of the sheath hub.

9. The transluminal sheath of claim 1, wherein the inner member hub further comprises a dilator inflation port and a guidewire lumen.
