Abstract
Abstract A medical device for treating a defective heart valve. The medical device comprises a delivery sheath and an implantable device moveably disposed within the delivery sheath. The implantable device further comprises a distal expandable basket, a proximal expandable basket, and a connecting member coupling at a first end to the distal expandable basket and at a second end to the proximal expandable basket. Each of the distal expandable basket and proximal expandable basket is in a collapsed state during delivery and an expanded state after deployment. An actuator is releasably coupled to the implantable device. When coupled to the implantable device, the actuator can move the implantable device in a way to allow for positioning of the distal and proximal expandable baskets.
