Monitoring structure is also positioned within the tip structure for measurement of the electrical potentials in a biological tissue. Passages are positioned within the tip in a variety of manners for directing the fluid flow through the tip means to the exterior surface of the tip to control the temperature and form a protective fluid layer around the tip. A fluid source is positioned at one end of the catheter for supplying a fluid flow through the catheter to the tip means. Vacuum extractors have replaced forceps for many situations in which assistance is required to achieve vaginal delivery. The ablation catheter also includes a tip for monitoring electrical potentials, and applying electrical energy to a biological tissue. Ai Vacuum Ovens is dedicated to providing professional, laboratory-grade vacuum purge equipment to BHO extraction artists & companies. The ablation catheter includes a catheter body. The average outside diameter of the tube may be, for example, less than 150 mils and has a finger grip that compression fits into a recess defined by the outer surface of the fetal contact cup for a lower profile and easy positioning of the fetal contact cup onto the flexion point of the fetal head.Ībstract: The invention relates to an ablation catheter which controls the temperature and reduces the coagulation of biological fluids on a tip of a catheter, prevents the impedance rise of tissue in contact with the catheter tip, and maximizes the potential energy transfer to the tissue, thereby allowing an increase in the lesion size produced by the ablation. Thus the fetal vacuum cup is less intrusive during insertion and is more easily maneuverable, especially when the fetus is malpresenting in, for example, the high occipitoposterior or high occipitolateral positions. The tube has a very small average outside diameter compared with conventional fetal vacuum tubes. The other end of the tube can be connected with a vacuum source and with a handle. One end of a tube is attached to the fetal contact cup such that vacuums within the tube are applied within the fetal contact cup. Abstract: The fetal contact cup portion of a fetal vacuum cup has an inside surface which, when applied to a fetal head, defines a fetal contact chamber with the fetal head.
