Abstract: The present technology includes systems and methods for invasively adjusting implantable devices for selectively controlling fluid flow between a first body region and a second body region of a patient. For example, in many of the embodiments described herein, a catheter can be used to mechanically and/or electrically engage an implanted medical device. Once the catheter engages the medical device, the catheter can (i) increase a dimension associated with the medical device, such as through mechanical expansion forces, and/or (ii) decrease a dimension associated with the medical device, such as by heating a shape memory component of the medical device above a phase transition temperature.

Abstract: Provided are surgical instruments, and more particularly, surgical instruments that may be manually operated to perform laparoscopic operations or various surgical operations.

The device is deployable underneath the bodily organ such that a lower portion of the bodily organ is supported by at least a portion of each of the two walls.

Abstract: A left atrial appendage occluder comprises an elastic closure disc, and a supporting structure connecting with the closure disc and being located on one side of the closure disc, with the supporting structure comprising a central end connecting with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchoring thorn is set near the end of at least one strut with the anchoring thorn toward the closure disc. The left atrial appendage occluder has a stable structure, a good positioning and sealing effect on the cavity wall in the left atrial appendage, and it is easy to position repeatedly; it can also be recycled before separating from a conveyor. When in surgical operation, the left atrial appendage occluder can select the position area based on the actual shape and size of the patient's left atrial appendage, so the surgical risk is lowered.

Abstract: A system and method for nerve decompression comprise a knife unit having a parallel upper limb and lower limb terminating proximally at the cap of the tubular sheath and a triangular shaped surgical cutting blade disposed vertically in between the upper limb and the lower limb. Upper limb and lower limb extend distally beyond the cutting blade and have open slots to facilitate proper positioning and engaging of the tissue while allowing visualization of less routing structure. The knife receives the probe head of an endoscope just behind cutting blade for proper visualization and illumination. The guiding system comprises a handle unit and a pair of parallel guides with long open slots that act as a cannula of adjustable diameter. The open slots on parallel guides facilitate 360 degree visualization of the surroundings and also prevent derailing of endoscopic knife unit while passing through it.

Abstract: Consistent with disclosed embodiments, systems, devices, methods, and computer readable media for filling a hollow body structure may be provided. In some implementations, an endovascular instrument for filling a hollow body structure may be provided and may include an elongated member configured to exhibit differing coiling properties along a length thereof. The elongated member may include a first region configured to bend within the hollow body structure to form a stabilizing frame. The elongated member may also include a second region located proximal to the first region and configured to bend, after formation of the frame, substantially within the frame, thereby forming a curved mass substantially within the frame. The first region and the second region may be interconnected. The embodiments may further include at least one structural property that differs between the first region and the second region.

Abstract: Embodiments of the present disclosure provide an introducer device for introducing a medical device into a patient's vasculature. In one embodiment, the introducer device comprises a housing, a distal sheath adapted to be inserted into a patient's vasculature with the housing positioned outside of the patient's vasculature, a hemostatic seal mounted within the housing, and a tube positioned within the housing and movable longitudinally relative to the hemostatic seal between a proximal position and a distal position. In the proximal position, a distal end of the tube is positioned proximal to the hemostatic seal with the hemostatic seal closed. In the distal position, the distal end of the tube extends through the hemostatic seal and permits the medical device to be inserted through the housing and into the patient's vasculature without contacting the hemostatic seal.
