Skirt for implantable medical device

An implantable medical device comprising:

• an implantable vascular device configured to be implanted within vascular anatomy of a patient;
• and
• a skirt attached to the implantable vascular device, the skirt including:
• a seamless tubular structure, the tubular structure being formed from a textile material;
• and
• a plurality of protrusions extending radially outwardly from the tubular structure, the protrusions formed within and integral with the tubular structure, each protrusion including an initial shape, wherein the protrusions are configured to:
• flatten with pressure applied in a radially inward direction with respect to the tubular structure;
• and
• recoil with pressure at least partially removed to regain the initial shapes of the protrusions, such that the protrusions conform to the vascular anatomy to create a seal between the implantable vascular device and the vascular anatomy.

A skirt for creating a seal between an implantable vascular device and vascular anatomy of a patient, the skirt comprising:

• a seamless tubular structure, the tubular structure being formed from a thermoformed textile;
• and
• a plurality of protrusions extending radially outwardly from the tubular structure, the protrusions formed within and integral with the tubular structure, the plurality of protrusions including at least one of pleats extending along the tubular structure, rings extending at least partially around a circumference of the tubular structure, and discrete bumps at least partially covering the tubular structure, each protrusion including an initial shape, wherein the protrusions are configured to:
• flatten with pressure applied in a radially inward direction with respect to the tubular structure;
• and
• recoil with pressure at least partially removed to regain the initial shapes of the protrusions, such that the protrusions conform to the vascular anatomy to create the seal between the implantable vascular device and the vascular anatomy.
