Publication number: 20240398417Abstract: A detachment mechanism and a delivery catheter are used to enable delivery and detachment of an implant (1). The detachment mechanism includes a detacher (10), a first control member (20) and a second control member (30). A distal end of the detacher (10) is configured for engagement of the implant (1) therewith. The detacher (10) defines a through hole (11). The first control member (20) and the second control member (30) are detachably engaged with or directly joined to each other. When distal ends of the first control member (20) and the second control member (30) are inserted through the through hole (11) and engaged with each other, the first control member (20) and the second control member (30) are locked against the detacher (10). When the first control member (20) is pulled and removed from the through hole (11), the first control member (20) and the second control member (30) are detached from the detacher (10).Type: ApplicationFiled: August 17, 2022Publication date: December 5, 2024Applicants: SHANGHAI TRULIVE MEDTECH CO., LTD., JIANGSU TRULIVE MEDTECH CO., LTD.Inventors: Yantao SUN, Jing ZHAO, Yunyan SUN, Wei ZHANG, Haoran XU, Dong HE, Haijun ZHANG

Publication number: 20240374406Abstract: An implant delivery handle, a delivery system and a method of operation thereof are disclosed. The implant delivery handle is able to switch an inner catheter (1) between unlocked and locked configurations through pivoting a locking knob (43) about an axis of the inner catheter (1) to cause a locking part (42) to exert or withdraw a radial pressure on the inner catheter (1). The implant delivery handle has a simplified structure and can be operated more easily. Moreover, the locking knob (43) for the inner catheter (1) and the control handwheel (33) for the flexible catheter (2) employ distinguishable designs, which effectively prevent a surgeon from being confused with the two actions.Type: ApplicationFiled: August 19, 2022Publication date: November 14, 2024Applicant: JIANGSU TRULIVE MEDTECH CO., LTD.Inventors: Yunyan SUN, Jing ZHAO, Wei ZHANG, Jing WEN

Publication number: 20240303553Abstract: This application describes systems and methods for generating machine learning models (MLMs). An exemplary method includes obtaining a sample and user input data characterizing a product or service. A subset of the data is selected from the sample based on sampling the sample according to the user input data. An MLM is trained by applying the data subset as training input to the MLM, thereby providing a trained MLM to emulate a customer selection process unique to the product or service. A user interface (UI) configured to receive other user input data and cause the trained MLM to execute on the other user input data, thereby testing the trained MLM, is presented. A summary of results from the execution of the trained MLM is generated and presented in the UI. The summary of results indicates a contribution to the trained MLM of each of a plurality of features.Type: ApplicationFiled: April 29, 2024Publication date: September 12, 2024Inventors: David Sheehan, Siavash Yasani, Bingjia Wang, Yunyan Zhang, Qiumeng Yu, Ruochen Zha, Adam Kleinman, Sean Javad Kamkar, Lingzhi Du, Saar Yalov, Jerome Louis Budzik

Publication number: 20240293244Abstract: The present invention provides an implant delivery handle, an implant system, a delivery system and a method of operation thereof. The implant delivery handle includes two conveyance sub-systems both oriented along an axial direction of a catheter assembly, in which a distal one is coupled to a proximal portion of an outer tube in the catheter assembly, and a proximal one is coupled to a proximal portion of an inner tube in the catheter assembly. Each of the conveyance sub-systems comprises a synchronous conveying device and a ratchet device fixed to the synchronous conveying device. The ratchet device is configured to enable safe self-locking, transmission and guidance of the outer or inner tube through the synchronous conveying device. In this way, both the inner and outer tubes can be locked in one direction, avoiding opposite movement of the inner or outer tube caused by incorrect operation of an operator.Type: ApplicationFiled: August 20, 2021Publication date: September 5, 2024Applicants: SHANGHAI TRULIVE MEDTECH CO., LTD., JIANGSU TRULIVE MEDTECH CO., LTD.Inventors: Wei ZHANG, Haoran XU, Jing WEN, Yunyan SUN

Publication number: 20150311072Abstract: The present invention provides a reproducible preliminary in-situ oxide removal step for patterned self-assisted III-V semiconductor nanowire growth. Here “in-situ” means located within the same treatment environment or apparatus as the nanowire growth process, e.g. with a molecular beam epitaxy (MBE) apparatus or the like. Providing an in-situ process may prevent the formation of a thin oxide layer during transfer of the substrate into the nanowire growth apparatus.Type: ApplicationFiled: April 21, 2015Publication date: October 29, 2015Applicants: UCL Business PLC, Gasp Solar ApSInventors: Martin Aagesen, Yunyan Zhang, Jiang Wu, Huiyun Liu

Patent number: 7259767Abstract: The present invention relates to a method and system for segmenting texture of multi-dimensional data indicative of a characteristic of an object. Received multi-dimensional data are transformed into second multi-dimensional data within a Stockwell domain based upon a polar S-transform of the multi-dimensional data. Principal component analysis is then applied to the second multi-dimensional data for generating texture data characterizing texture around each data point of the multi-dimensional data. Using a classification process the data points of the multi-dimensional data are partitioned into clusters based on the texture data. Finally, a texture map is produced based on the partitioned data points. The present invention provides image texture segmentation based on the polar S-transform having substantially reduced redundancy while keeping maximal data variation.Type: GrantFiled: May 2, 2005Date of Patent: August 21, 2007Assignee: Calgary Scientific Inc.Inventors: Ross Mitchell, Hongmei Zhu, Yunyan Zhang, Alan Law
