  • Publication number: 20250367022
    Abstract: An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

  • Publication number: 20250241784
    Abstract: Systems, devices, and methods for delivering one or multiple materials into a body space (e.g., to occlude the body space) and/or for removing one or multiple materials from a body space (e.g., to open or reopen the body space) are described. Delivering material into the vas deferens of the male reproductive tract for contraception, removing material from the vas deferens to restore patency of the vas deferens, delivering material into the fallopian tubes of the female reproductive tract for contraception, and removing material from fallopian tubes to restore patency of the fallopian tubes is described. Confirming access to a body space is described. Agitating materials in a body space is described. Creating turbulence in a body space is described.

  • Patent number: 12370078
    Abstract: Delivery systems for providing occlusive hydrogels in a tube lumen or void space within the body including but not limited to a reproductive tract such as the vas deferens or fallopian tubes for contraception are described. The delivery systems contain mechanisms that confirm proper placement of the system in the bodily lumen prior to the delivery of the occlusive material. The systems also can contain a confirmatory mechanism that demonstrates the blockage or occlusion in the bodily lumen has been achieved following the deposition of the occlusive material. Another aspect of this application is to provide a removal system that delivers dissolving material, agitates, aspirates, and confirms the patency of the bodily lumen following the removal of the occlusive material if so desired by the patient for the return to fertility.

  • Publication number: 20220218390
    Abstract: Disclosed are access devices that can be used to safely guide instruments, such as EP ablation catheters, to a therapy site such one within the pericardial space of the heart. The access devices include integrated visualization, illumination, stabilization, and safety features in a single platform that can, for example, more safely and efficiently identify and ablate several ventricular tachycardia (VT) locations on the left ventricle of the heart.

  • Publication number: 20190366048
    Abstract: Everting balloon systems and methods for using the same with an alignment element for stability and anti-rotation of the everting balloon are disclosed herein. The systems can be configured to access and deliver instruments, media, or other catheters into bodily lumens and cavities. The alignment element eliminates the potential for the everting membrane to become twisted or rotated which could impact access or the ability of the system to deliver materials. A compliance member facilitates internal pressurization of the everting catheter system.
