Tensioned sheathing aids
First Claim
1. A medical device apparatus, comprising:
- a medical implant including a braided anchor member operatively connected to a delivery system, the delivery system including a handle, an outer sheath extending distally from the handle, and an inner catheter disposed within the outer sheath; and
a sheathing aid connecting the delivery system to the medical implant, the sheathing aid being configured to guide the medical implant into the outer sheath upon compression of the sheathing aid as the sheathing aid is withdrawn into the outer sheath;
wherein the sheathing aid includes a plurality of filaments extending from the inner catheter to a proximal end of the braided anchor member, and a cleat disc disposed within a coupler ring fixedly attached to a distal end of the inner catheter;
wherein the plurality of filaments is releasably coupled to the cleat disc,wherein the delivery system includes at least one actuator element extending from the inner catheter to the medical implant, the at least one actuator element being configured to reversibly shift the braided anchor member from an elongated delivery configuration to an enlarged deployed configuration,wherein each of the at least one actuator element passes through the cleat disc.

Abstract
A medical device apparatus may include a medical implant including an anchor member configured to actuate between a delivery configuration and a deployed configuration operatively connected to a delivery system, the delivery system including an outer sheath and an inner catheter disposed within the outer sheath, and a sheathing aid connecting the delivery system to the medical implant, the sheathing aid being configured to guide the medical implant into the outer sheath upon relative closing movement therebetween. The sheathing aid may include a plurality of tethers extending from the inner catheter to a proximal end of the anchor member, and a release mechanism slidably disposed within a coupler ring coupled to a distal end of the inner catheter. The plurality of tethers may be releasably coupled to the release mechanism.
