This disclosure is directed toward sealable and repositionable implant devices that are provided with one or more improvements that increase the ability of implants such as endovascular grafts to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and / or with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant.

Methods, systems, and devices for an adaptable blood pump are disclosed herein. The blood pump can be part of a mechanical circulatory support system that can include a system controller and the blood pump. The blood pump can include a rotary motor and a control unit that can communicate with the system controller. The blood pump can determine when communication with the system controller is established or has been lost. The blood pump can retrieve one or several back-up parameters when communication with the system controller has been lost, and can operate according to these back-up parameters.

The invention discloses a sensor device capable of controlling insertion angle in subcutaneous tissue, the sensor device comprises a fixing base and an inserting base provided with a hard needle tubing through hole and rotatably connected to the fixing base. The sensor device capable of controlling insertion angle in subcutaneous tissue has the advantages that it is convenient to insert the insertion type biosensor into the subcutaneous tissue and adjust the insertion angle of the insertion type biosensor in the skin tissue, so that the insertion type biosensor can have longer effective length in the subcutaneous tissue; the measured data is more accurate and near to the actual data.

The invention relates to a plugging stent for a left auricle. The plugging stent comprises a reticular body and a tail connected with the reticular body, wherein the tail is overturned inwards to forma blunt shape, so that the contact area between the tail and the left auricle is enlarged, the situation that left auricle walls and internal tissue are damaged by the tail end of the stent in the transplanting process and after transplanting is avoided, the damage of the surgery to the patient is reduced, simultaneously, risks of hydropericardium, perforation and the like can also be avoided, and the safety of the surgery operation is higher; and in addition, the maneuverability of the plugging machine is better, and under the situation that the transplanting position is not ideal, the transplanting position can be adjusted only through propelling the plugging machine, so that the operation difficulty is reduced, and the medical care effect is improved.

The present invention provides an intraoperative stent delivery system and an intraoperative stent system. The intraoperative stent includes a main body stent and a side branch stent arranged on the main body stent and extending outward. The intraoperative stent delivery system includes a main body an inner lining and a side branch inner lining arranged on the main body inner lining, the side branch bracket is configured to be sleeved on the side branch inner lining, the main body bracket is configured to be sleeved on the main body inner lining, and the side branch The inner liner is oscillatingly arranged on the main body inner liner to synchronously drive the side support bracket to swing relative to the main body support. In the present invention, by setting the side branch lining that can swing relative to the main body lining, the side branch stent can be swayed synchronously relative to the main body stent, which facilitates alignment and easy implantation of the side branch stent and the left subclavian artery during operation, and avoids thoracotomy The time of freeing and suturing the left subclavian artery in the operation is too long, which increases postoperative complications, reduces the difficulty of operation, shortens operation time, and expands the scope of surgical indications.
