Apical puncture access and closure system

摘要

A device, system, and method for providing access to, and sealing of, a body organ includes an implant device. An implant device has a main body having an internal access lumen, with a plurality of prongs extending from a distal end of the main body. The main body can include two lumens, one slidable within the other, to form a single continuous lumen with an adjustable length. The main body has an expanded configuration with an expanded diameter, and an unexpanded configuration with an unexpanded diameter. The prongs have a generally straight configuration where they extend distally of the distal end of the main body, and a bent configuration where the prongs bend around so that their tips extend proximally of the distal end of the main body. The device may include a hemostatic barrier to prevent fluid leakage therethrough when the main body is in the unexpanded configuration.

1. A method for providing access through an organ wall, comprising:
providing a hemostatic sealing device comprising a main body having a distal portion with a distal lumen and a proximal portion with a proximal lumen, where the distal lumen is sized to receive the proximal lumen to create a continuous lumen through the main body, the sealing device further comprising a plurality of prongs extending from a distal end of the distal portion of the main body, wherein the main body lumen has a first diameter, and the plurality of prongs are radially retracted with respect to the main body; forming a hole in an organ wall of an organ from an outside surface to an interior surface; advancing the hemostatic sealing device into the hole in the organ wall until the distal end of the main body is advanced at least partially into an interior space of the organ; adjusting the overall length of the device by sliding the proximal lumen into or out of the distal lumen such that the distal portion of the main body is within the interior space of the organ and the proximal portion of the main body is positioned outside the organ wall; extending the prongs so that the prong tips are extended radially away from the main body; and securing the hemostatic sealing device in the organ wall by retracting the distal portion of the main body at least partially out of the interior space of the organ and embedding the prong tips into the organ wall from the interior surface thereof, thereby providing access to the interior space of the organ from the outside surface through the sealing device.
