Abstract
A system for treating cardiac dysfunction can include an expandable device for insertion into a heart, a foot configured to contact a portion of the heart, a support frame, and a membrane coupled to the support frame. The support frame can include a plurality of radially expandable struts each having a first free end configured to extend beyond the foot and a second end coupled to the foot. The plurality of radially expandable struts can include a plurality of staggered stops, and each of the stops can be positioned on a respective one of the struts proximal to the first free end of the respective one of the struts. Method for treating cardiac dysfunction can include implanting the systems described herein into a chamber of the heart.
Claims15
An implant loading system comprising:
- a funnel for loading an expandable implant into a catheter for delivery to a heart, the funnel having a flared first end and a second end, wherein the flared first end comprises a tapering receptacle for receiving and collapsing the expandable implant, and a second portion at the second end comprises a lumen, the second end including a coupling element for removably coupling the funnel to a sleeve;
- and
- a sleeve configured to be removably coupled to the second end of the funnel and having a coupling element located in a center portion of the sleeve for mating with the coupling element at the second end of the funnel, the sleeve including a tubular portion distal to the coupling element of the sleeve that is configured to be positioned within the second portion of the funnel.
