VALVE DELIVERY SYSTEM WITH PINLESS RELEASE MECHANISM
First Claim
1. A medical device, comprising:
- an inner shaft having a distal end region;
a valve implant releasably coupled to the distal end region;
wherein the valve implant is capable of shifting between an elongated configuration and an expanded configuration;
a deployment sheath capable of being disposed about the valve implant when the valve implant is in the elongated configuration;
a post assembly disposed along the valve implant;
wherein the post assembly includes a release member that is axially slidable along the post assembly;
a rod designed to engage the release member, wherein the rod is designed to shift the valve implant between the elongated configuration and the expanded configuration; and
wherein axially shifting the release member along the post assembly releases the rod from the post assembly and deploys the valve implant.

Abstract
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an inner shaft having a distal end region. A valve implant may be releasably coupled to the distal end region. The valve implant may be capable of shifting between an elongated configuration and an expanded configuration. A post assembly may be disposed along the valve implant. The post assembly may include a release member that is axially slidable along the post assembly. The medical device may also include a rod designed to engage the release member. The rod may be designed to shift the valve implant between the elongated configuration and the expanded configuration. Axially shifting the release member along the post assembly may release the rod from the post assembly and deploy the valve implant.

19. A method for delivering a valve implant, the method comprising:
-
advancing a delivery system through a body lumen to a position adjacent a target site, the delivery system comprising; an inner shaft having a distal end region, a valve implant releasably coupled to the distal end region, a post assembly disposed along the valve implant, a release member axially slidable along the post assembly, a rod for shifting the valve implant between a delivery configuration and a deployment configuration, the rod being capable of engaging the release member, and proximally retracting the rod to begin shifting the valve implant from the delivery configuration toward the deployment configuration; assessing the positioning of the valve implant relative to the target site; and further proximally retracting the rod to axially shift the release member along the post assembly, release the rod from the post assembly, and complete shifting of the valve implant to the deployment configuration. - View Dependent Claims (20)
