SYSTEM AND MINIATURE DEVICES FOR DELIVERING A THERAPEUTIC COMPONENT TO A TREATMENT SITE IN A PATIENT
Publication number: 20220409871Abstract: A miniature device is provided for use in a system configured to deliver a therapeutic component to a treatment site in a patient. The miniature device comprises at least one steering portion comprising a magnetic material, and at least one carrier portion affixed to the steering portion and comprising the therapeutic component. The carrier portion is configured to at least partially dissipate under one or more predetermined conditions at the treatment site, thereby releasing the therapeutic component. Further provided is a system comprising one or more such miniature devices and a magnetic inducing apparatus configured to be operated to generate a varying magnetic field, thereby remotely controlling motion of the miniature device.Type: ApplicationFiled: November 4, 2020Publication date: December 29, 2022Applicant: BIONAUT LABS LTDInventors: Michael SHPIGELMACHER, Alex KISELYOV, Florent CROS, Darrell HARRINGTON, Suehyun CHO, John CAPUTO -
Publication number: 20220265312Abstract: A method and apparatus for safely and reliably accessing a subarachnoid space (SAS) or other target area of a patient is provided in which a tube having at least one lumen with a tissue puncture device therein is inserted into the patient near the tissue. The lumen has a suction port at one end adapted to suction the dura/arachnoid tissue away from the pia mater so that the tissue can be punctured to access the SAS space. The movement of the needle in the lumen is controlled by controlling a magnetic field. Tissue puncture devices for use alone or in connection with the apparatus are also provided.Type: ApplicationFiled: July 28, 2020Publication date: August 25, 2022Applicant: BIONAUT LABS LTD.Inventors: Michael SHPIGELMACHER, Michael KARDOSH, Be'eri Berl KATZNELSON, Eran OREN, Alex KISELYOV, Florent CROS, Suehyun CHO, Darrell HARRINGTON, Olin PALMER

Patent number: 8391700Abstract: A method and system for facilitating focusing of a miniature camera are disclosed. One or more lenses can be attached to a MEMS stage. The MEMS stage can be moved by a Lorentz actuator. The MEMS stage can be configured to limit movement of the lens(es) to a single degree of freedom to inhibit misalignment thereof with respect to an imaging sensor. The stage can be biased to a predefined position thereof, e.g., for focus at infinity. A metal cover can inhibit electromagnetic interference and can limit movement of the lens(es).Type: GrantFiled: September 1, 2010Date of Patent: March 5, 2013Assignee: Digitaloptics Corporation MEMSInventors: Roman C.
