초록 ▼

A catheter hub includes a distal assembly including a distal hub member adapted to be fixedly attached to an outer catheter and a proximal assembly including a proximal hub member adapted to be fixedly attached to an inner catheter disposed through the outer catheter. An elongate member connects the proximal and distal assemblies such that the proximal and distal assemblies can translate longitudinally relative to one another.

1. A catheter hub and handle assembly, comprising: a distal hub member coupled to a flexible outer catheter member adapted for intravascular delivery of fluids and a proximal hub member coupled to a flexible inner catheter member adapted for intravascular delivery of fluids, the flexible inner catheter member being disposed within the flexible outer catheter member;a distal handle member adapted to detachably couple to the distal hub member;a proximal handle member adapted to detachably couple to the proximal hub member and having a receiving recess in a distal section of the proximal handle member, the proximal handle member further comprised of a plurality of unenclosed channels formed on a surface of the proximal handle member adapted to accommodate a plurality of tubes;the plurality of tubes configured to be in fluid communication with the flexible inner catheter; andan elongate handle member proximally extending from the distal handle member and passing into the receiving recess and movably coupled to the proximal handle member such that the distal handle member is capable of longitudinal translation relative to and independent of the proximal handle member along a longitudinal axis of the elongate member. 2. The catheter hub of claim 1 wherein the proximal handle member is adapted to detachably accommodate the proximal hub via any of the following: a fastener, a quick-connect fitting, an adhesive, a press fit, a clamp, a snap fit, a magnetic connection, or a threaded connection. 3. The catheter hub of claim 1 wherein the distal handle member is adapted to detachably accommodate the distal hub via any of the following: a fastener, a quick-connect fitting, an adhesive, a press fit, a clamp, a snap fit, a magnetic connection, or a threaded connection. 4. The catheter hub of claim 1 wherein the elongate handle member is integrally fabricated with the distal handle member and is adapted to slide into the proximal handle member. 5. The catheter hub of claim 1 wherein the proximal handle member further comprises a recess and a translation lock disposed at a distal end of the recess. 6. The catheter hub of claim 5 wherein the proximal handle member further comprises a receiving opening which is configured to receive the elongate handle member there through. 7. The catheter hub of claim 6 wherein the translation lock engages the elongate handle member through the proximal handle member to secure the proximal handle member to the distal handle member and fix relative motion between the proximal handle member and distal handle member. 8. The catheter hub of claim 7 wherein the engagement between the translation lock and the elongate handle member may be through any of the following: a press fit, a snap fit, an internal ratchet arrangement, longitudinally spaced detents, or a screw and groove. 9. The catheter hub of claim 1 wherein the proximal hub member is detachably connected to the distal hub member. 10. The catheter hub of claim 9 wherein the proximal hub member is detachably connected to the distal hub member via any one of the following: a quick-connect fitting, a press fit, a snap fit, magnetic connection, or a threaded connection. 11. The catheter hub of claim 10 wherein the proximal hub member comprises a first connector including a flexible snap fit member configured to snap together with a complimentary second connector disposed on the distal hub member. 12. The catheter hub of claim 11 wherein the second connector is a lumen of the distal hub member. 13. The catheter hub of claim 11 wherein the first connector is a polygonal interface and the second connector is a complimentary polygonal interface. 14. The catheter hub of claim 9 wherein the distal hub member is configured to radially deform onto an outer surface of the proximal hub member to provide further mechanical interlocking. 15. The catheter hub of claim 1, wherein the proximal handle member is configured to be gripped by a user thereof. 16. The catheter hub of claim 1 wherein the distal handle member comprises lateral projections adapted to accommodate a finger on a distal side of each of the lateral projections.
