摘要: A shunt device for creating a shunt in an atrial septum includes magnets coupled to inner loops of a coil comprising at least two inner loops and two outer loops, with a diameter of each of the inner loops being less than a diameter of the outer loops. The coil is made of a shape memory alloy (SMA) and is adapted to exert a compressive force upon layers of tissue caught between the inner loops of the coil. The magnets are adapted to provide additional compressive force to adjacent inner loops of the coil, thereby further causing the coil to cut through the layers of tissue and create a shunt. The diameter of the resultant shunt is less than the diameter of the outer loops, thereby preventing the outer two loops from passing through the created shunt. At least one end of the coil has a connection means for connecting with a delivery device.

摘要: An anastomosis device includes magnets coupled to a wire capable of changing shape from a straight wire into a coil when deployed within a body. The coil exerts compressive force upon layers of tissue caught between loops of the coil. The compressive force is enhanced by attractive forces between magnets coupled with adjacent loops of the coil and causes the coil to cut through the tissue layers, creating an anastomosis. One end of the wire is preferably provided with a connecting member, such as a screw or a nut, for connecting with a delivery device.

摘要: Methods of preventing, treating, and/or controlling a hemorrhage in an organ of a patient include providing electrical stimulation to the arteries, veins, nerves innervating the arteries or veins, or walls of the organ. The apparatus has at least one electrode operably connected to a stimulus generator and placed in electrical communication with an artery, vein, nerve, or organ wall. An electrical stimulus generator causes an electrical stimulus to be administered to the artery, vein, nerve, or wall through the at least one electrode, where the electrical stimulus is effective for preventing, treating, and/or controlling a hemorrhage.

摘要: A system and method for treating anorectal dysfunction includes implanting, in a minimally invasive manner, an electro-medical device for stimulation of two or more separate and distinct anatomical or histological structures of the anorectal region. Electrodes operably connected to the device are positioned proximate the target anatomical or histological structures. The device provides either the same or different stimulation algorithms to each anatomical or histological structure. Smooth muscle, such as the internal anal sphincter, is provided with a continuous stimulation algorithm, while skeletal muscle, such as the external anal sphincter, is provided with an on demand stimulation algorithm. Varying stimulation algorithms applied to multiple structures results in improved anorectal function without developing muscle fatigue and tolerance.

摘要: The present application discloses devices that ablate human tissue. The device comprises a catheter with a shaft through which an ablative agent can travel, a liquid reservoir and a heating component, which may comprise a length of coiled tubing contained within a heating element, wherein activation of said heating element causes said coiled tubing to increase from a first temperature to a second temperature and wherein the increase causes a conversion of liquid within the coiled tubing to vapor, a reusable cord connecting the outlet of the reservoir to the inlet of the heating component, and a single use cord connecting a pressure-resistant inlet port of a vapor based ablation device to the outlet of the heating component.

摘要: Ablation catheters and systems include multiple inline chambers for containing and heating an ablative agent. The heating chamber includes one or more channels to increase the contact surface area of the ablative agent with the walls of the heating chamber to provide more efficient heating. Induction heating is used to heat a chamber and vaporize a fluid within by wrapping a coil about a ferromagnetic chamber and providing an alternating current to the coil. A magnetic field is created in the area surrounding the chamber which induces electric current flow in the chamber, heating the chamber and vaporizing the fluid inside. Positioning elements help maintain the device in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.
