Abstract

Aspects herein relate to a medical device for providing a leak-resistant seal for use in a vascular access device. In various embodiments, a device for vascular access hemostasis is included. The device can include an enclosure configured to at least partially receive a medical device, the enclosure defining a cavity. The enclosure can have a first seal portion and a second seal portion, the cavity disposed between the first seal portion and the second seal portion. The enclosure can include the second seal portion comprising a split, septum seal. The enclosure can include a barrel in structural communication with the second seal portion. The device can include a constriction ring disposed around the barrel, the constriction ring interfacing with the second seal portion to limit movement of the split, septum seal.

Claims (30)

1. A device for vascular access hemostasis, the device comprising:

an enclosure configured to at least partially receive a medical device, the enclosure defining a cavity and having

a distal end;

a proximal end;

a first seal portion;

a second seal portion, the cavity disposed between the first seal portion and the second seal portion; and

a plurality of support ribs operably connected to the second seal portion;

a barrel in structural communication with the second seal portion; and

a constriction ring disposed around the barrel, the constriction ring interfacing with the second seal portion to limit movement of the second seal portion;

wherein the constriction ring is disposed around the barrel between the support ribs and the distal end.

2. The device of claim 1 , wherein the support ribs are configured for compressive interfacing with a housing.

3. The device of claim 1 , the barrel defining a notch around the outer perimeter of the barrel, the notch configured to receive the constriction ring.

4. The device of claim 1 , the barrel defining a retaining flange around the outer perimeter of the barrel.

5. The device of claim 4 , wherein the retaining flange is disposed between the constriction ring and the distal end.

6. The device of claim 1 , the constriction ring comprising a polygonal shape in cross-sectional.

7. The device of claim 1 , the constriction ring comprising a non-polygonal shape in cross-sectional.

8. The device of claim 1 , the constriction ring comprising an elastomeric material.

9. The device of claim 1 , wherein the first seal portion comprises a hole seal.

10. The device of claim 1 , wherein the first seal portion comprises a ring seal.

11. The device of claim 1 , wherein the second seal portion is configured to be held in compression by a mating housing.

12. The device of claim 1 , wherein the second seal portion defines a single axial split 45 degrees offset from the plurality of support ribs.

13. A sealing device comprising:

a device enclosure defining a cavity, the device enclosure comprising a distal end and a proximal end, wherein the device enclosure is configured to compressively interface with a housing,

a first seal portion in communication with the device enclosure, the first seal portion defining an opening;

a second seal portion in communication with the device enclosure, the second seal portion defining a split;

a plurality of support ribs operably connected to the second seal portion; and

a constriction ring disposed around the device enclosure, the constriction ring disposed over the split of the second seal portion and disposed between the support ribs and the distal end.

14. The sealing device of claim 13 , the plurality of support ribs in compressive communication with the second seal portion.

15. The sealing device of claim 14 , wherein the plurality of support ribs are offset from the split by about 45 degrees.

16. The sealing device of claim 14 , wherein the plurality support ribs are substantially symmetrical relative to the split.
