Abstract
A carotid artery stenting system can include a sheath that is inserted into an artery. The sheath can include a distal portion having a first inflatable balloon, a first distal port configured to enable a stent to exit the sheath, and a second distal port configured to enable a second inflatable balloon to exit the sheath. A distance between the first inflatable balloon and the second inflatable balloon can be customized by moving a catheter distally or proximally inside a lumen of the sheath.
Claims24
A carotid artery stenting system comprising:
- an elongated sheath configured for insertion into an artery, the elongated sheath comprising:
- a distal portion having:
- a first inflatable balloon located on a first outer perimeter of the elongated sheath;
- a first distal port configured to enable a stent to exit the elongated sheath;
- and
- a second distal port located on a second outer perimeter of the elongated sheath and proximal to the first distal port and the first inflatable balloon, wherein the second distal port is configured to enable a first catheter to exit the elongated sheath;
- a proximal portion having a first inflation port, a first access port, and a second access port;
- a first lumen extending between the first access port and the first distal port;
- and
- a second lumen extending between the first inflation port and a first interior of the first inflatable balloon;
- and
- a third lumen extending between the second distal port and the second access port.
A carotid artery stenting method comprising:
- obtaining an elongated sheath having a distal portion and a proximal portion;
- and
- inserting the elongated sheath into an artery,
- wherein the distal portion of the elongated sheath comprises:
- a first inflatable balloon located on a first outer perimeter of the elongated sheath;
- a first distal port configured to enable a stent to exit the elongated sheath;
- and
- a second distal port located on a second outer perimeter of the elongated sheath and proximal to the first distal port and the first inflatable balloon, wherein the second distal port is configured to enable a first catheter to exit the elongated sheath,
- wherein the proximal portion of the elongated sheath comprises a first inflation port and a first access port,
- wherein the elongated sheath further comprises a first lumen and a second lumen,
- wherein the first lumen extends between the first access port and the first distal port,
- wherein the second lumen extends between the first inflation port and a first interior of the first inflatable balloon,
- wherein the proximal portion of the elongated sheath comprises a second access port proximal to the first distal port and the first inflatable balloon,
- and
- wherein the elongated sheath further comprises a third lumen extending between the second distal port and the second access port.
