The present methods, systems, and devices relate to an occlusion device for blocking a biological tube, the biological tube being prone to a peristaltic wave having a wave length, and where the occlusion device comprises at least two sections, where each section is connected by at least one narrowing to at least one other section. The occlusion device is of an elastic material, and each section is configured to deform when a force is applied by the peristaltic wave, and the length of at least one of the at least two sections corresponds substantially to the wave length of the peristaltic wave in the biological tube, so as to absorb the peristaltic wave. The methods, systems, and devices relates to reversible contraception of female and/or male gendered species intervening with biological tube, which are responsible for transportation of fertility fluids, such as the transportation of spermatozoes or oocytes in for example the human reproductive system.

Methods and devices for treating and occluding a female patient's fallopian tubes to provide permanent or extended birth control or sterilization.

Delivery systems and methods for forming and delivering biomaterials from two components are described herein. In particular, apparatus and methods for performing controlled delivery of multicomponent delivery of biomaterials into or onto a body part, such as a body lumen are described. More specifically, in some embodiments, the apparatus and methods are directed towards controlled delivery of micro-volumes of biomaterials into or onto a target location, the micro-volumes being defined as 0.001 mL-1 mL (or 1 μL-1,000 μL) of volume.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

A drug delivery system is provided in the form of a controlled release, bioerodible pellet for subdermal implantation. The pellet is bioerodible, and provides for the sustained release of a pharmacologically active agent over an extended time period. As such, the drug delivery system finds significant utility in chronic drug administration. Bioerosion products are water soluble, bioresorbed, or both, obviating the need for surgical removal of the implant. Methods for manufacturing and using the drug delivery system are also provided.

Systems and methods for imaging an object that are capable of capturing an image or images of the object using an imaging modality, automatically detecting and analyzing the image or images by way of converting the image or images to at least one binary image, and analyzing the at least one binary image to extract and/or segment regions-of-interest (ROIs) from the at least one binary image. The object can be or include an implantation, occlusion, medical device, body lumen, tissue, organ, duct, and/or vessel. The imaging modality can be or include X-ray, CT, MRI, PET, and/or ultrasound, or any combination thereof. Also included are compositions of soft, implantable materials with one or more carbon-based material, nanomaterial, and/or allotrope present in an amount sufficient as an ultrasound contrast agent effective for days, months, or years and which compositions are useful in the automated imaging methods of the invention.
