Abstract: A cannula for minimally invasive surgical tricuspid valve repair, which is constituted by a tube (5). equipped, at its distal end. with a head (2) consisting of a cone-shaped rigid ring (3) and connected to it on the other side of a flexible ring (4). where the flexible ring (4) in the folded state has a disk shape, and on top of the head (2) there is an axial hole (8) leading to the interior of the cannula (1). and where on the whole length of the head (2) and on a part of the tube (5) near the connection to the head (2), from the inside, there is a thin guide sleeve (6) which, on the section of the rigid ring (3) is permanently attached to the surface of its wall, while on its remaining length, it is slidably movable relative to the wall of the tube (5).

Abstract: A cryoprobe having a working tip formed of two coaxial flexible internal and external tubular lines, wherein the cross-section diameter of the internal line is substantially smaller than the cross-section diameter of the external line, and the length is slightly smaller than the length of the external line. The external line ends with a top closing the working tip of the cryoprobe, while the end of the internal line is open, and there are openings evenly distributed across the circumference on at least half of the section of the internal line. On the section from the handle to the end located under the top, a resistance wire is spirally wound on the internal line, wherein the distance between the wall of the external line and the wall of the internal line is larger than the diameter of the resistance wire. On the external line, no further from the top located on the top of the working tip than ? of the length thereof, there is a temperature sensor connected to the handle by a power line.

Abstract: The cryoapplicator for minimally invasive surgical cardiac ablation includes a fastening part, an insulation part and an effector tip. A pin is connected with the fastening part on one end, and with the effector tip on the second end. The effector tip is bent by 60° to 90° angle in the side view in relation to pin longitudinal axis, and by 5° to 60° angle in the top view. A thermal insulation cover is located on the pin with the possibility to slide along the longitudinal axis.

Abstract: A cannula for minimally invasive surgical tricuspid valve repair, constituted by two coaxial tubes—an outer short one (2) and an inner long one (3), of which the inner long tube (3) is slidably movable relative to the outer short tube (2), and its proximal end is constituted by a head (4) which in the folded position has a cone shape with an axial inlet hole (5) in the axis of the upper base, while in the unfolded position, with the outer short tube (2) slid off in the distal direction, the head (4) has the shape of a cup extending outwardly. The outer edge of the cup has a diameter about three times the inner diameter of the cannula (1). The outer short tube (2) is equipped with at least one rigid tie rod (8) the free end of which extends along the inner wall of the inner long tube (3) beyond its distal end.

Abstract: A cannula for minimally invasive surgical tricuspid valve repair, which is constituted by a tube, equipped, at its distal end, with a head consisting of a cone-shaped rigid ring and connected to it on the other side of a flexible ring. The flexible ring in the folded state has a disk shape, and on top of the head there is an axial hole leading to the interior of the cannula. On the whole length of the head and on a part of the tube near the connection to the head, from the inside, there is a thin guide sleeve which, on the section of the rigid ring is permanently attached to the surface of its wall, while on its remaining length, it is slidably movable relative to the wall of the tube. The guide sleeve is equipped with at least two tie rods attached, on one end, opposite to each other, to the wall of the guide sleeve, and their free ends extend along walls of the cannula beyond its distal end.

Abstract: The liquid nitrogen cryosurgical apparatus with a set of Suwalski cardiac surgery cryoprobes comprises of the liquid nitrogen container (1) installed on the mobile frame (11) comprising of a base and a profiled extension arm. The container (1) cooperates with the supply head (5) which is detachably connected to the supply line (2) by means of connector (7) fastening the line (2) to the head (5). The cooling medium used is the liquid nitrogen which is transported from the container (1) through the supply line (2) and is supplied to the selected Suwalski cardiac surgery cryoprobe (4) tip seated in the socket inside the handle (3) of the supply line (2). The supply line (2) comprises of four coaxially arranged flexible hoses, and the first internal hose (14) supplies the liquid nitrogen. The electrical system of the supply head (5) is connected by means of the power supply connector (8), located on the wiring harness end, with the control panel (6) installed on the mobile frame (11) extension arm.
