摘要： Conventional vasectomy techniques suffer from a number of disadvantages and potential complications, including, for example, a substantial risk for the development of hematomas, swelling, and post-surgical pain, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing vasectomy instruments, kits, and methods that allow for a rapid, reliable, less invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

摘要： There is provided a method for controlling a flow of eggs in a uterine tube formed by a uterine tube wall of a patient. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the uterine tube wall) at least one portion of the uterine tube wall to influence the flow of eggs in the uterine tube, and stimulating the constricted wall portion to cause contraction of the uterine tube wall portion to further influence the flow of eggs in the uterine tube. The method can be used for restricting or stopping the flow of eggs in the uterine tube, or for actively moving the fluid in the uterine tube, with a low risk of injuring the uterine tube.

摘要： Described are methods for reversible occlusion of a body lumen by way of degradation as a result of exposure to one or more stimuli such as light. The methods include administering one or more substance(s) into a body lumen of a subject and forming a stimuli-responsive polymer mass in the body lumen from the one or more substance(s). The mass is sufficient to occlude the body lumen in a manner that prevents transport of at least one material through the body lumen and is susceptible to on-command reversal in the body lumen upon exposure to one or more stimuli. The methods include administering one or more stimuli to a polymer mass in a body lumen for a time and intensity to cause the reverse the polymer mass. The methods are particular useful for applications in which it is desirable to temporarily occlude a body lumen, such as male and female contraception.

摘要： A hydraulic implantable restriction device for restricting a luminary organ of a patient. The hydraulic implantable restriction device comprises: a first hydraulic restriction element adapted to restrict a first portion of the luminary organ, and a second hydraulic restriction element adapted to restrict a second portion of the luminary organ, and a control unit adapted to control the first and second restriction elements for automatically switching between restricting the first and second portion of the luminary organ, for creating a less damaging restriction. The control unit is adapted to automatically switch between restricting the first and second portion of the luminary organ on the basis of at least one of: a lapsed time being between 10 minutes and 6 months, and the patient using the function of the restricted luminary organ.

摘要： Methods for the synthesis and use of several variations of styrene maleic acid-based polymers and the hydrogel tissue bridges that can be formed from such polymers. Specifically, a method is disclosed for synthesizing a styrene maleic acid-based polymer that can be dissolved in DMSO and injected into the vasa deferentia of male subjects, creating a hydrogel tissue bridge. This hydrogel tissue bridge can occlude the vas deferens, thus forming an effective male contraceptive. Additionally, this male contraceptive can be reversed by injecting the lumen of the vas deferens with a basic buffer solution to dissolve and remove the hydrogel tissue bridge.

摘要： Contraceptive and/or sterilization methods and devices are disclosed which may improve the speed of tubal occlusion and mechanisms for anchoring for a contraceptive device. In accordance with some embodiments, improvements may be made to the delivery catheter to induce trauma and create faster tubal occlusion, improvements may be made to the occlusion device to prevent migration and induce trauma, and improvements may be made to the occlusion device to reduce the total volume of in-growth required compared to conventional expansive occlusion devices.
