Abstract

A hub assembly for connection to a medical device. The hub assembly may comprises an outer component having a proximal end, a distal end, and a cavity extending from the proximal end to the distal end. The hub assembly may further include an insert having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end positioned at least in part within the cavity of the outer component. The insert may have a lumen extending from the proximal end to the distal end thereof. The outer component may be formed from a first material and the insert may be formed from a second material different from the first material.

First claim

What is claimed is:

1 . A hub assembly for connection to a medical device, the hub assembly comprising:
an outer component having a proximal end, a distal end, and a cavity extending from the proximal end to the distal end; an insert having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end positioned at least in part within the cavity of the outer component, the insert having a lumen extending from the proximal end to the distal end thereof; wherein the outer component is formed from a first material and the insert is formed from a second material different from the first material.

2 . The hub assembly of claim 1 , wherein the second material is more compliant than the first material.

3 . The hub assembly of claim 1 , further comprising one or more windows extending through a wall of the outer component.

4 . The hub assembly of claim 3 , wherein the one or more windows are filled with a compliant material to form one or more elastically deformable regions in the outer component.

5 . The hub assembly of claim 4 , wherein the one or more elastically deformable regions forms a unitary structure with the insert.

6 . The hub assembly of claim 4 , wherein the one or more elastically deformable regions are separate components from the insert.

7 . The hub assembly of claim 3 , further comprising a clamping mechanism configured to be removably positioned over the one or more elastically deformable regions.

8 . The hub assembly of claim 3 , wherein the clamping mechanism is configured to exert biasing force on an outer surface of the one or more elastically deformable regions to deform the one or more elastically deformable regions towards a center of the outer component.

9 . The hub assembly of claim 1 , wherein the distal end of the insert extends distally beyond the distal end of the outer component.

10 . The hub assembly of claim 9 , wherein a portion of the insert extending distally beyond the distal end of the outer component forms a tapered strain relief portion.

11 . The hub assembly of claim 1 , wherein the distal end of the outer component is configured to be coupled to a medical device.

12 . The hub assembly of claim 11 , wherein, when coupled, a distal opening of the medical device is configured to be adjacent to the proximal end of the insert.

13 . A hub assembly for connection to a medical device, the hub assembly comprising:
an outer component having a proximal end configured to be connected to a medical device, a distal end, and a cavity extending from the proximal end to the distal end; and an inner component having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end positioned at least in part within the cavity of the outer component; a lumen extending from the proximal end to the distal end of the inner component, the lumen having a taper from a proximal opening to an intermediate region thereof; wherein the distal end of the insert extends distally beyond the distal end of the outer component and forms a tapered strain relief portion; and wherein the outer component is formed from a first material and the insert is formed from a second material more elastic than the first material.

14 . The hub assembly of claim 13 , wherein the inner component is configured to reduce a volume of the cavity of the outer component and minimize converging of particles from an injected solution.

15 . The hub assembly of claim 13 , wherein the outer component comprises a poly carbonate.

16 . The hub assembly of claim 13 , wherein the inner component comprises a thermoplastic urethane.

17 . A hub assembly for connection to a medical device, the hub assembly comprising:
a hub body having a proximal end, a distal end, and a lumen extending therebetween; a deformable region positioned at a location intermediate to the proximal end and the distal end; a docking region positioned adjacent to the deformable region, the docking region having a first stop mechanism positioned on proximal side thereof and a second stop mechanism positioned on a distal side thereof; and a ring slidably disposed over the hub body, the ring slidable between the deformable region and the docking region.

18 . The hub assembly of claim 17 , wherein when the ring is disposed over the docking region, the deformable region is in an undeformed state.

19 . The hub assembly of claim 17 , wherein when the ring is disposed over the deformable region, the ring exerts a biasing force on the deformable region to bias the deformable region into an elastically deformed state.

20 . The hub assembly of claim 19 , wherein when in the elastically deformed state, the deformable region is biased towards and into the lumen.
