The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing means, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing means such that the contraction of the beating heart causes orgy minimal excess motion at the surgery site. By fixing the position of the stabilizing means in a configuration where the motion of the beating heart is effectively eliminated, the surgeon is able to stabilize the beating heart for the duration of the procedure. The stabilizing means may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention. In certain preferred embodiments, the stabilizing means is affixed to a semi-rigid support which is caused to become rigid, by any of a variety of techniques, such that the position of the stabilizing means becomes fixed by the support, and the heart remains substantially motionless for the duration of the procedure.

A free floating fishing apparatus includes a float and a spool that is positioned on the float for holding a supply of line to be dispensed. A line holding beam is mounted on the float and has a line guide that enables fishing line to be spooled from the spool through the line guide and then underwater for fishing. Rigging such as a hook, sinker or the like can be attached to the free end portion of a line. The spool is comprised of two sections, a non-rotating section which is received over the float and a rotating section received over the non-rotating section. A finite length of line is wound on the rotating section and a selected amount is payed out prior to fishing. The free end of the payed out line is attached to a hook and perhaps a float and the float and hook are dropped into the water. Depending upon the amount of line wound and whether the spool sections are locked during fishing, a finite amount of line may pay our after the fish has struck the hook.

A free floating fishing apparatus includes a float and a spool that is positioned on the float for holding a supply of line to be dispensed. A hook setting trigger mechanism is mounted on the float and has a line guide that enables fishing line to be spooled from the spool through the line guide and then underwater for fishing. Rigging such as a hook, sinker or the like can be attached to the free end portion of a line. The trigger assembly includes an arm that is pivotally movable between extended and retracted positions. The arm is spring loaded to bias the arm toward the retracted position. A sear plate enables the arm to be retained in an intermediate position that is in between the extended and retracted positions, but closer to the extended position. The sear plate is spring loaded to move the sear out of engagement with the arm when the arm is moved beyond the intermediate position toward the extended position such as when a fish bites the hook and pulls on the line. The arm includes a line support that holds the line so that when the arm travels under spring tension toward the retracted position, the line below the float is pulled quickly for setting the hook.

Devices and methods for minimally invasive harvesting of a vessel, especially the saphenous vein for coronary artery bypass grafting, are disclosed which facilitate a minimally invasive vessel harvesting procedure. Generally, an instrument is provided which facilitates introduction of vessel harvesting tools through a minimally invasive incision, and provides the capability to separate the vessel from surrounding tissue while minimizing trauma to the patient and preserving the patency of the vessel. The instrument includes a mechanism for separating the vessel from surrounding tissue and may also include mechanisms for severing side branches from the vessel during the harvesting procedure. In one embodiment, an integrated vessel harvesting assembly is provided which may rotate around a vessel and provides a unitary mechanism for separating the vessel from surrounding tissue and for severing the side branches.
