Patent number: 12290280Abstract: A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.Type: GrantFiled: February 4, 2021Date of Patent: May 6, 2025Assignee: Boston Scientific Medical Device LimitedInventors: Hitendra Purohit, Agrim Mishra, Deepak K.

The enclosure is configured to move relative to the body between a first position and a second position. The enclosure is fluidly decoupled from the fluid source when in the first position such that the pressurized fluid released into the body is not in fluid communication with the agent stored in the enclosure. The enclosure is fluidly coupled to the fluid source when in the second position such that the pressurized fluid released into the body is in fluid communication with the agent stored in the enclosure.Type: ApplicationFiled: October 15, 2024Publication date: April 24, 2025Applicant: Boston Scientific Medical Device LimitedInventors: Nitesh Ghananil BAVISKAR, Nabarun BHOWMICK

Patent number: 12268380Abstract: A tissue traction device including a scaffold structure configured to anchor the tissue traction device in place such that a tissue traction element is anchored upon deployment of the scaffold structure and without further manipulation of the tissue traction device (such as to grasp tissue or otherwise anchor the tissue traction element to tissue). The scaffold structure may be self-supporting/self-standing to be in a deployed expanded configuration to anchor the tissue traction device with respect to the tissue. The tissue traction element may be pivotably coupled to the scaffold structure, such as to a rigid element of the scaffold structure. The tissue traction element, when anchored by the scaffold, exerts a force (e.g., traction force) on a region of target tissue to which the tissue traction element is coupled, such as via a tissue engagement member.Type: GrantFiled: December 17, 2021Date of Patent: April 8, 2025Assignee: BOSTON SCIENTIFIC MEDICAL DEVICE LIMITEDInventors: Nabarun Bhowmick, Deepak K.
