摘要： An occlusion device (100, 200) includes a fixing portion (120, 220), where the fixing portion (120, 220) includes a plurality of supporting bodies (122, 221); the plurality of supporting bodies (122, 221) include a plurality of supporting sections (124, 223) spaced apart along a circumferential direction of the fixing portion (120, 220), where tail ends of at least two adjacent supporting sections (124, 223) bend and extend towards the interior of the fixing portion (120, 220) to form a convergence section (125, 224), by which the tail ends of the at least two adjacent supporting sections (124, 223) are connected; the at least two adjacent supporting sections (124, 223) and the corresponding convergence section (125, 224) form a set of suspended sections (126, 225), all of which are spaced and suspended along the circumferential direction of the fixing portion (120, 220). The suspended sections (126, 225), circumferentially spaced and suspended with a large active space, can adaptively deform according to different internal tissue structures, which not only has a better anti-injury effect, but also can prevent a single supporting section (124, 223) from being locally deformed to a large extent, and buffer the supporting section (124, 223) with a single rod and ends not closed from greater pressure on the inner wall of the left atrial appendage.

摘要： The present invention relates to a plugging device, including a first part, and a second part connected to the first part. The first part or the second part includes a plurality of braiding filaments and a gathering member; portions of the braiding filaments that are close to one ends of the braiding filaments cooperate to form a disc face. The plugging device further includes a film member. The film member at least covers part of an outer surface of the disc face; the gathering member includes an inner sleeve and an outer sleeve, both of which are hollow and sleeved; and one end of each braiding filament and at least part of a gathering region of the film member are all fixed to the gathering member. The present invention further relates to a plugging device, including a first part. The first part includes a plurality of braiding filaments and a gathering member. One end of each braiding filament is fixed to the gathering member. The first part is provided with at least one disc face; some of the plurality of braiding filaments form a gathering portion by means of shape convergence; the gathering member is located in a space enclosed by the gathering portion; and at least one disc face formed by cooperation of the gathering portion is flat and sealed.

摘要： A left atrial appendage (LAA) occluder includes a sealing portion and a fixing portion connected to the sealing portion, and one or more sealed seed sources encapsulated with radioactive particles. The sealed seed sources are arranged on the sealing portion and/or the fixing portion (20) and configured for forming an annular isolation band on an inner wall of an LAA after the radioactive particles are released. The annular isolation band is configured for blocking the electrical signal conduction between the LAA and a left atrium. In the LAA occluder, the annular isolation band is formed on the inner wall of the LAA by the release of the radioactive particles in the sealed seed sources arranged on the sealing portion and/or the fixing portion.

摘要： A filter , comprising a main body part . The main body part comprises a heart-proximal end , a plurality of connecting segments , and a first filter mesh connecting between the heart-proximal end and the plurality of connecting segments . An end of the connecting segments that is connected to the first filter mesh is bent towards a central longitudinal axis of the filter to form a bending part. A vertical distance between a proximal end of the bending part and the central longitudinal axis of the filter is less than a vertical distance between a distal end of the bending part and the central longitudinal axis of the filter .

摘要： A puncturing device and an anchoring device, the puncturing device including: a puncturing needle, an inflatable anchoring balloon, and a catheter which passes through a proximal end and distal end of the anchoring balloon, the puncturing needle being movably accommodated within the catheter; in a filled state, a central area of an end portion of the distal end of the anchoring balloon is depressed towards the proximal end to form a depressed area, and a distal end of the catheter is located within the depressed area. The anchoring device includes the anchoring balloon and the catheter. The puncturing device may improve the accuracy and success rate of puncturing, and after puncturing is complete, an expansion balloon may be transported along a guide wire to expand a puncturing opening by simply withdrawing the puncturing needle and a push rod.
