Abstract

Organ manipulation devices for atraumatically grasping the surface of an organ and repositioning the organ to allow access to a location on the organ that would otherwise be substantially inaccessible. Methods of accessing a beating heart, retracting the heart using an organ manipulation apparatus, and stabilizing a surgical target area with a stabilizer. Both the organ manipulator and stabilizer are fixed to a stationary object which may be a sternal retractor. A system for performing beating heart coronary artery bypass grafting includes a sternal retractor, organ manipulator and stabilizer.

Claims

1-101. -101. (canceled)

102. A suction assembly for an organ manipulation apparatus, comprising:

a hollow shaft connectable to a vacuum source;

a suction cup connected to the hollow shaft and configured to establish a relative negative pressure, via the vacuum source, in a space between the suction cup and an organ and to exert sufficient force on the organ to move the organ when the suction member is moved after first being placed against the organ;

a clevis arranged to translate along a length of the hollow shaft; and

a roller comprising an elongated body with an axis of rotation substantially perpendicular to the length of the hollow shaft to permit rotational movement between the clevis and the hollow shaft.

103. The assembly of claim 102, further comprising a bias member configured to exert a biasing force on the clevis in a direction along the length of the hollow shaft.

104. The assembly of claim 102, wherein the clevis includes a shaft protruding therefrom configured to connect the suction assembly to an organ manipulation apparatus.

107. An assembly for establishing an interface limiting movement between a support structure and a beating heart, the assembly comprising:

a suction member comprising a shaft and shaped to engage a heart'"'"'s apex region;

a fitting establishing a fluidic interface between the suction member and tubing associated with the fitting;

a suspension disposed between the fitting and the suction member, the suspension comprising a roller rotatably mounted to a base member and coupled to the shaft, said roller comprising an elongated body with a longitudinal axis of rotation substantially perpendicular to a length of said shaft.

108. The assembly of claim 107, wherein the assembly is configured to allow for a limited amount of translation of said suction member with respect to the suspension.

109. The assembly of claim 108, further comprising a spring located along a length of the shaft.

110. The assembly of claim 109, wherein the spring is located between the roller and the fitting.

111. The assembly of claim 109, wherein the spring comprises a helical portion.

112. The assembly of claim 109, wherein the spring is a helical spring.

113. The assembly of claim 107, wherein the suction member is cup shaped.

114. A surgical method performed on a beating heart comprising:

attaching a suction cup of a heart positioning device to a surface of the heart by suction;

rotating the heart via the suction cup so as to position the heart in a retracted position to perform a surgical procedure; and

movably suspending the heart via a suspension of the heart positioning device so as to allow for contraction and relaxation of the heart during the surgical procedure and wherein the suspension is movably biased to oppose the weight of the suction cup and heart attached thereto.

115. The method of claim 114, wherein the heart is movably suspended via a suspension of the heart positioning device and wherein the suspension comprises a roller rotatably mounted to a base member and a shaft movably coupled to the roller.

116. The method of claim 115, wherein a spring is operatively associated with at least one of the roller or shaft.

117. The method of claim 114, further comprising the steps of:

contacting the heart with a stabilizer;

stabilizing a surgical site of the heart; and

performing the surgical procedure at the surgical site.

118. The method of claim 114, wherein the heart is movably suspended so as not to substantially restrict contractibility and cardiac output of the heart in the retracted position.

119. The method of claim 114, further comprising translating the heart via the suction cup so as to position the heart in a retracted position to perform the surgical procedure.

120. The method of claim 114, wherein the suspension is movably biased via a spring of the suspension.
