  • Patent number: 11534283
    Abstract: Porous implantable devices for housing one or more therapeutic agents are disclosed herein. The implantable devices include a porous outer wall defining an interia or void. The interior void houses a carrier material carrying a first therapeutic agent. The implantable devices are made by patterning at least a portion of a polymerizable substrate into a polymerized three-dimensional porous outer wall surrounding an interior void. This can be achieved by two-photon polymerization techniques. A first therapeutic agent is then added to the interior void, which is then sealed. Methods of treating diseases using the implantable devices are disclosed herein. The methods include implanting the implantable device at a target area and locally releasing a therapeutically effective dosage of a first therapeutic agent from the interior void. The implantable devices can also be used in methods of screening potentially therapeutic agents for desired biological responses.

  • Publication number: 20210205032
    Abstract: The present disclosure provides a system and method for controlling an articulating member including a tool. The method includes determining a first confidence indicator based on a manual control mode for the articulating member, determining a second confidence indicator based on an autonomous control mode for the articulating member, generating an allocation function based on the first confidence indicator and the second confidence indicator, and generating a control command for the articulating member based on the allocation function.

  • Publication number: 20210077195
    Abstract: The present disclosure provides a system and method for controlling an articulating member including a tool. The system may include a dual camera system that captures near-infrared (NIR) images and point cloud images of a tissue or other substance that includes NIR markers. The system may generate a three-dimensional (3D) path based on identified positions of the NIR markers, may filter the generated path, and may generate a 3D trajectory for controlling the articulated arm of a robot having a tool to create an incision along the filtered path. In a shared control mode, an operator may generate manually control commands for the robot to guide the tool along such a path, while automated control commands are generated in parallel. One or more allocation functions may be calculated based on calculated manual and automated error models, and shared control signals may be generated based on the allocation functions.

  • Patent number: 10925474
    Abstract: The present disclosure is a device and method associated with the delivery of medical devices in the pericardial space using a minimally invasive approach with direct visualization. More specifically, the device can be used to deliver permanent pacing, defibrillation and cardiac resynchronization leads, as well as leadless pacemakers for cardiac rhythm management to the epicardial surface of the heart. A subxiphoid procedure is proposed as a minimally invasive alternative to thoracotomy, while the delivery tool incorporates a camera for direct visualization of the procedure. The tool also incorporates a steerable catheter to provide selective control of the placement and orientation of the medical device in the pericardial space.

  • Patent number: 10895020
    Abstract: A method for generating a electro spun fiber medical implant including determining dimensions of a portion of anatomy of a patient corresponding to the electro spun fiber medical implant via medical imaging, generating a model of the portion of the anatomy based on the dimensions, the model including one or more solid areas and one or more void areas encompassed within the one or more solid areas, inverting the model to generate a mandrel model, the mandrel model generated based on the one or more void areas, generating the mandrel based on the mandrel model, the mandrel including at least one electrically conductive material therein, and applying an electro-spinning process to the mandrel to generate the electro spun fiber medical implant which circumscribes the mandrel, wherein the mandrel is removable from within the electro spun fiber medical implant after a disassembly process.

  • Publication number: 20210001086
    Abstract: The present disclosure is related to a device for gripping catheters that are used in interventional cardiac procedures without causing internal catheter damage. The present disclosure will allow the operator to maintain improved stability and maneuverability compared with current approaches, including, primarily, digital manipulation, which can lead to fatigue, instability and inappropriate catheter movement. Specifically in the pediatric population where small movements can lead to severe and permanent complications, the present disclosure has the potential to increase the safety profile of already high-risk interventional catheterization and electrophysiology procedures.
