Methods for removing a biomaterial implant and reversing occlusive effects of the biomaterial implant are described. In particular, methods for performing removal of biomaterial implants without damage to a body lumen where the biomaterial was previously implanted are presented. More specifically, methods of reversing an implant within a vas deferens using an ablation device are described.

A tubal occlusion contraceptive device/appliance (100/200) and methods of implant and removal. The device (100) includes a plurality of barbs (124) with some preferentially resisting movement in a first axial direction and others preferentially resisting movement in a second opposite axial direction. The device (100) is implanted in a Fallopian Tube (FT) through a sheath. The appliance (200) includes an oversized cap (220) to prevent continued insertion of appliance (200) into a Fallopian Tube (FT), and a plurality of barbs (240) to facilitate a first axial direction slide fit insertion of the appliance (200) into a Fallopian Tube (FT) while preferentially resisting axial movement in a second opposite axial direction out from the Fallopian Tube (FT) once inserted. The barbs (240) can be replaced with screw threads (250).

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.

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.
