The present invention describes a method and kit for performing a prostate medical or surgical treatment.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

A container replacement system for replacing a fluid container with a replacement fluid container, wherein the fluid container contains a cryogenic fluid and is coupled to a pressure line, includes a control valve that vents the cryogenic fluid within the pressure line, a pressure sensor that senses a line pressure of the cryogenic fluid and generates sensor output and a controller that receives sensor output and determines whether to replace the fluid container. If the line pressure is below a threshold line pressure, the controller determines replacing the fluid container is permissible. Contrarily, if the line pressure is above the threshold line pressure, the controller determines replacing the fluid container is not permissible. The container replacement system further includes a GUI that instructs whether replacing the fluid container is permissible.

A flow blocking catheter including an inner tube, a flow blocking member and an outer tube is provided. The flow blocking member is self-expandable and sleeved on an exterior of the inner tube. At least a proximal end of the self-expandable flow blocking member is attached to an outer circumference of the inner tube. The outer tube is movably sleeved on the exterior of the inner tube to restrict an expansion of the flow blocking member. In this way, expansion of the flow blocking member is able to be controlled simply by pushing/retracting the outer or inner tube to offer a fast shifting between different configurations. The flow blocking member is able to occlude blood flow with a controllably expansion to lower stimulation to the wall of the blood vessel and avoid the easy bursting of the balloon.

A flow blocking catheter including an inner tube, an outer tube and a flow blocking member is provided. The flow blocking member has one end attached to an outer circumference of the inner tube and the other end attached to a distal end of the outer tube. The flow blocking member is configured to expand as the outer tube moves toward a distal end of the inner tube and to collapse as the outer tube moves away from the distal end of the inner tube. In this way, expansion of the flow blocking member is able to be controlled simply by pushing/retracting the outer or inner tube to offer a fast shifting between different configurations. The flow blocking member is able to occlude blood flow with a controllably expansion to lower stimulation to the wall of the blood vessel and avoid the easy bursting of the balloon.

Some systems and methods for operating a vessel occlusion catheter may include a control and inflation device to control the filling of the balloon in such a manner that the vessel wall will not be overstressed while the safe occlusion of the blood vessel is achieved.

A balloon is provided for selectively moving an esophagus away from an ablation site. The balloon is received through an oral cavity and into the esophagus of a patient. A deflecting member is provided in the tube, the balloon, or both, to selectively distort to bend the balloon and/or the tube to move the esophagus away from the ablation site. The deflecting member may comprise at least one of a strip made of a shape memory material that is responsive to the receipt of a stimulus to deflect to a predetermined shape, a strip that is made of or contains a ferrous material and that deflects in response to the presence of a magnetic field, and a selectively tensionable cable, wire, or string. The deflecting member may be supplemented by a stiffening strip that is located in the balloon and that causes the balloon to expand circumferentially and asymmetrically when inflated.

A dynamic balloon angioplasty system for applying a dynamic pressure to fracture hardened materials embedded within an elastic conduit. The system having a pressure source system outputting at least a first predetermined pressure from a pressure source outlet, and an angioplasty unit fluidly coupled to the pressure source outlet receiving at least the first predetermined pressure. The angioplasty unit having an angioplasty inflation device, an angioplasty balloon connector, and an oscillating mechanism selectively actuated to output a plurality of pressure pulses to the angioplasty balloon via a fluid communication path. A control system is configured to determine an optimal hydraulic pressure oscillation frequency and amplitude for a given procedure and output a control signal to the oscillating mechanism, and monitor a pressure signal to detect fracture of the hardened material within the elastic conduit or system failure or leakage.

A pessary system for providing pelvic floor support for USL and other ligaments. The pessary has an elongated probe with independently inflatable balloons each located substantially the same distance from the insertion end of the probe and which inflate into separate radial sectors. The probe can be inserted into a vaginal cavity and the balloons inflated provide mechanical support to the USLs. Independent inflation of each balloon allows the mechanical USL support provided to be varied on left and right sides to compensate for differences in the degree of degradation and positioning of the USL ligaments on either side.
