Abstract

An implantable device includes an outer tubular member defining a longitudinal axis and a lumen. The outer tubular member includes: an outer wall portion having a plurality of first strands defining a plurality of first openings therebetween, the outer wall portion having a first porosity; and an inner baffle portion disposed within the lumen, the inner baffle portion including a plurality of second strands defining a plurality of second openings therebetween, the inner baffle portion having a second porosity that is lower than the first porosity of the outer wall portion.

First claim

What is claimed is:

1. A method for treating pulsatile tinnitus, the method comprising:
imaging cerebral blood vessels adjacent cochlea to identify irregular blood flow having a rotational flow component; and
implanting an implantable device into a jugular vein, the implantable device including:
an outer tubular member defining a longitudinal axis and a lumen, the outer tubular member having an outer wall portion having a plurality of first strands defining a plurality of first openings therebetween, the outer wall portion having a first porosity; and
an inner baffle portion disposed within the lumen, the inner baffle portion including a plurality of second strands defining a plurality of second openings therebetween, the inner baffle portion having a second porosity that is lower than the first porosity of the outer wall portion, wherein the inner baffle portion is configured to disrupt the rotational flow component.

2. The method according to claim 1 , wherein the inner baffle portion includes an inner tubular member.

3. The method according to claim 2 , adjusting a diameter of the inner tubular member to adjust the second porosity of the inner baffle portion.

4. The method according to claim 1 , wherein the inner baffle portion extends along the longitudinal axis.

5. The method according to claim 4 , wherein the inner baffle portion bisects the lumen.

6. A method for treating pulsatile tinnitus, the method comprising:
imaging cerebral blood vessels adjacent cochlea to identify irregular blood flow having a rotational flow component; and
implanting an implantable device into at least one of a jugular bulb or a jugular vein to disrupt the rotational flow component.

7. The method according to claim 6 , wherein the implantable device includes:
a tubular member defining a longitudinal axis and a lumen, the tubular member having an outer wall portion having a plurality of first strands defining a plurality of first openings therebetween, the outer wall portion having a first porosity.

8. The method according to claim 7 , wherein the implantable device further includes:
an inner baffle portion disposed within the lumen, the inner baffle portion including a plurality of second strands defining a plurality of second openings therebetween, the inner baffle portion having a second porosity that is lower than the first porosity of the outer wall portion.

9. The method according to claim 8 , wherein the inner baffle portion extends along the longitudinal axis.

10. The method according to claim 9 , wherein the inner baffle portion bisects the lumen.

11. The method according to claim 6 , wherein the implantable device includes a plurality of tubular members.

12. The method according to claim 11 , wherein the plurality of tubular members are arranged in a stacked configuration, such that each of the tubular members is arranged in parallel relative to each other.

13. The method according to claim 12 , wherein the plurality of tubular members are disposed in a grid pattern.

14. The method according to claim 13 , wherein the tubular member is at least one of a stent or a stent strut.
