Benefits of technology

Enables minimally-invasive heart procedures with reduced recovery time, stabilizing the heart during beating-heart surgeries and ensuring secure closure of punctures, reducing the need for extensive hospital stays.

Problems solved by technology

Conventional heart valve surgery is an open-heart procedure conducted under general anesthesia, and is a highly invasive operation.
These systems are mostly concerned with holding still a discrete surface area of the heart for direct operation thereon, and are not designed for operations carried out by instruments that extend within the beating heart, i.e., for intracardiac procedures.

Embodiment Construction

[0033]FIG. 1 depicts a cross-sectional view of a patient 10 where an intercostal incision opening 12 is created to access the patient's heart 14. The heart is a hollow muscular organ of a somewhat conical form, positioned between the lungs in the middle mediastinum and enclosed within the pericardium. The heart rests obliquely in the chest behind the body of the sternum and adjoining parts of the rib cartilages, and generally projects farther into the left than into the right half of the thoracic cavity so that about one-third is situated on the right and two-thirds on the left of the median plane. The heart is subdivided by septa into right and left halves, and a constriction subdivides each half of the organ into two cavities, the upper cavity being called the atrium, the lower the ventricle. The heart therefore consists of four chambers; the right and left atria, and right and left ventricles.

[0034]As seen in FIG. 1, the left ventricular apex (aka LVA) 16 is directed downward, fo...

Abstract

A system for stabilizing the heart via a helical needle, providing access to the interior of the heart via an introducer sheath, and forming a purse string suture using suture delivered by the helical needle. A helical needle projects distally from the device in a helical shape and terminates in a sharp distal tip. The helical needle is advanced into the heart wall, and is used to stabilize the heart and to pass a purse string suture through the heart tissue. An access port provides access to the interior of the heart via an opening passing through the heart wall in an area circumscribed by the helical needle. A length of suture may pass through the helical needle and exit at an opening at or near the needle distal tip. A free end of the length of suture may extend out of the distal tip and back into the hollow suture needle through the opening. The helical needle may have a deflection segment adjacent the distal tip that is more flexible than the rest of the helical distal portion of the helical needle.

Description

RELATED APPLICATIONS[0001]The present application is a divisional of U.S. patent application Ser. No. 13 / 301,515, filed Nov. 21, 2011, which claims priority under 35 U.S.C. §119 to U.S. Provisional Application Ser. No. 61 / 418,188, filed Nov. 30, 2010.
