A neostomy apparatus, including a grasping device, a cutting device and a control handle. The control handle includes a housing and a manipulation portion disposed in the housing, the manipulation portion can move axially relative to the housing; the grasping device or the cutting device includes an elongated member, and the manipulation portion drives the elongated member to move axially; the elongated member is partially located in the housing, and a first limiting structure is further disposed in the housing, the first limiting structure has a groove or a through hole, and a portion of the elongated member located in the housing is at least partially disposed in the groove or the through hole of the first limiting structure.

Neostomy apparatus

A left atrial appendage (LAA) occluder and an occluding system are provided. The LAA occluder includes a sealing portion and an ablation portion arranged in the sealing portion, as well as a hollow proximal connector at a proximal end of the sealing portion. The ablation portion is connected to the proximal connector. The ablation portion is used to freeze an LAA after being injected with cryogen so as to form an annular isolation band on an inner wall of the LAA for blocking the conduction of electrical signals between the LAA and a left atrium.

Left atrial appendage occluder and occlusion system

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 () 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.

Left atrial appendage occluder

A method for implanting an interventional medical device, including the following steps: delivering the distal end of the puncture needle into the right atrium via the inferior vena cava; locating the puncture site on atrial septum under X-ray fluoroscopy in a first perspective angle and a second perspective angle, and puncturing the atrial septum by the puncture needle through the puncture site; delivering the medical device to the left atrial appendage or left atrium for release under X-ray fluoroscopy in a first perspective angle. The implanting method of the disclosure does not require the use of a TEE device during implementation and provides benefits of a simple operation, short operation time, and easy implementation conditions, while also be easy to promote and popularize.
