Systems and devices for reducing the size of an internal tissue opening

摘要

A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The delivery device can include an actuating assembly configured to partially deploy the closure device by a first movement, and deploy a second portion of the closure device by a second movement. The delivery device can also include a release assembly to selectively release or disconnect the closure device from the delivery device. The delivery device can include a tip member coupled to the distal end of a catheter. The tip member can include a first passageway and a second passageway being in a spaced apart arrangement. A guidewire can be received into the first passageway to facilitate positioning of the delivery device. The second passageway can house and facilitate delivery of the closure device.

主权项

1. A medical implant delivery system for delivering a medical device in a human body, the delivery system comprising:
a handle; a catheter coupled to the handle and having a catheter lumen extending through a length thereof, the catheter including tether lines coupled with the handle and extending through the catheter lumen, the tether lines including three tether lines and being configured to be coupled to the medical device; and a tip portion including a proximal end, the proximal end coupled to a distal end of the catheter, the tip portion defining a first passageway and a second passageway each extending at least partially along a length through the tip portion, the first passageway configured to move over a guide wire and the second passageway, at the proximal end of the tip portion, configured to be substantially co-axial with the catheter lumen and the second passageway configured to contain and facilitate delivery of the medical device, the first passageway and the second passageway being in a spaced apart. non-coaxial arrangement, the first passageway being separate and distinct from the second passageway, and the second passageway defining a rectangular cross-section, defined laterally with respect to the length of the tip portion, at a distal tip end of the tip portion and at least partially along the length of the second passageway defined in the tip portion, wherein the rectangular cross-section is configured to orient the tether lines side-by-side in a linear configuration within the tip portion defined by the rectangular cross-section.
