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 within an opening in the post assembly, wherein a portion of the release member extends through 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 shifting the portion of the release member extending through the post assembly from a first axial position within the post assembly to a second axial position within the post assembly releases the rod from the post assembly and deploys the valve implant;
wherein the rod has a forked distal end region.

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.

8. 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 within an opening in the post assembly, wherein a portion of the release member extends through 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 shifting the portion of the release member extending through the post assembly from a first axial position within the post assembly to a second axial position within the post assembly releases the rod from the post assembly and deploys the valve implant; wherein a buckle member is coupled to the valve implant, the buckle member being configured to receive at least a portion of the post assembly therein; wherein the buckle member is designed to engage the release member and cause the portion of the release member extending through the post assembly to shift from a first axial position within the post assembly to a second axial position within the post assembly.

9. A medical device, 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 engaged with and axially slidable within an opening in 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 wherein axially shifting the release member along the post assembly releases the rod from the post assembly and deploys the valve implant; wherein the release member remains engaged with the post assembly after the rod is released from the post assembly; wherein the release member is a clevis pin extending through at least a portion of the post assembly; wherein the rod has a forked distal end region, wherein the post assembly has a side opening extending laterally from an axial lumen of the post assembly. - View Dependent Claims (10, 11, 12, 13, 14)
