Benefits of technology

[0014]The present invention is directed to devices and methods for accessing the interior of the heart without having to stop the heart from beating and while minimizing blood loss.

Problems solved by technology

Percutaneous treatment has several issues that make it less than desirable.
For one thing, the catheters and tools that are used for percutaneous cardiac procedures are limited in size because they must be threaded through the vasculature into the heart.
Maneuverability of a catheter which is threaded such a long distance is limited, which means that it is difficult and sometimes impossible to locate the working end of the catheter exactly at the area in the heart where treatment is needed.
This also adds to the total length of the procedure.
Another issue with percutaneous access can be various vascular complications such as b

Embodiment Construction

[0022]The device allows a physician to gain access to the interior of the heart, preferably in a minimally invasive manner, so that he or she can perform a medical procedure therein. The instrument port is designed to be temporarily implanted through the heart wall, to allow passage of one or more instruments into the heart while minimizing blood loss out of the heart.

[0023]FIG. 1 illustrates the device 10 as used to facilitate delivery of an ablation catheter into the left atrium of a patient's heart. It should be understood that although the instrument port is shown inserted through the apex of the left ventricle to facilitate access to the left atrium, it can be inserted through any area of the heart wall for access to any area of the heart. The port can also be used in other areas of the body. In addition, although the instrument port 10 is shown for delivery of an ablation catheter it can be used with a wide variety of instruments and in a wide variety of procedures.
