The utility model provides a kind of thoracolumbar orthotic instrument, it is related to the technical field of correction equipment.Thoracolumbar orthotic instrument includes fixed part, locking part and rope body.The number of fixed part and locking part is same and all is multiple, multiple locking parts are connected with multiple fixed parts one to one.Correspondingly, multiple fixed parts are all provided with rope part in one side wall, and the other side wall is provided with fixed part, and fixed part is used to be fixed in vertebral body;Locking part is also used to be fixed in vertebral body;Rope body is sequentially wound in the rope part of multiple fixed parts;Therefore, the stability of fixed part can be effectively enhanced by locking part and fixed part, to avoid displacement or rotation problem;And by rope body sequentially winding in the rope part of each fixed part, form continuous, uniform stress correction force system, improve correction stability, and can be according to patient individual situation and adolescent growth potential carry out scoliosis non-fusion dynamic adjustment;Thus, stable and effective correction support is provided for patient, and treatment effect and life quality are improved.

This invention provides a tether adjuster and its method of use. The tether adjuster includes a housing, a clamping mechanism, and a tension adjusting mechanism. The clamping mechanism is connected to the distal end of the housing and is capable of clamping an apical pad. The apical pad is used to connect to the proximal end of the tether, and the distal end of the tether is connected to a heart valve prosthesis. The clamping mechanism includes a first driving part and a jaw. The jaw includes two clamping arms symmetrically arranged circumferentially on the housing. The first driving part is connected to the two clamping arms respectively and is used to drive the distal ends of the two clamping arms to move in a direction of mutual approach to open the jaw, or to drive the distal ends of the two clamping arms to move in a direction of mutual approach to close the jaw. The tension adjusting mechanism is connected to the housing and to the proximal end of the tether, and is used to drive the proximal end of the tether to move relative to the heart valve prosthesis to adjust the tension of the tether. When adjusting the tension of the tether using the tether adjuster, two symmetrically arranged clamping arms are used to clamp the apical pad, so that the apical pad is subjected to symmetrical and balanced clamping force, maintaining the stability of the apical pad. This allows the operator to manipulate the tension adjustment mechanism to move the proximal end of the tether and thus adjust the tension of the tether.

A customizable inflatable bolster apparatus (100) may include a first leaf (102), a second leaf (104), or a balloon (108) disposed between the first leaf (102) and the second leaf (104) or on a single leaf. The balloon (108) may include an inflation port (110) and one or more tethers (112)(1)-(n)). The one or more tethers (112)(1)-(n)) may be disposed within the balloon (108) or around an external surface of the balloon (108). In response to the balloon (108) inflating, the one or more tethers ((112)(1)-(n)) may shape the balloon (108) into a desired shape. The apparatus (100) may apply a pressure to the tissue of patient and immobilize the tissue. The apparatus (100) may be applied to a skin graft, a patient's tissue, or a mucosa or fascia of the patient. The apparatus (100) may elute a substance, such as a pharmaceutical, into the tissue of the patient.

A medical device for occluding a left atrial appendage ("LAA") may include a proximal occluding member to cover an ostium of the LAA and a distal occluding member to be received within a cavity of the LAA. A connecting member may connect the proximal occluding member to the distal occluding member. An occluding material may be uncoupled from the proximal occluding member in a delivery condition of the proximal occluding member, and uncoupled from the distal occluding member in a delivery condition of the distal occluding member, the occluding material configured to at least partially fill and occlude the LAA. In some examples, the distal occluding member is entirely excluded, and the medical device includes other anchoring provisions, such as tethers that latch onto a back wall of the LAA.

The cushion includes a bladder that encloses an interior cavity and retains a gas in the interior cavity. A stretch component is disposed in the interior cavity and includes a stretch layer and a plurality of tethers connected to the stretch layer. The stretch layer is connected to an inner surface of the bladder such that the tethers span the interior cavity. The bladder has an inwardly projecting tie that connects the inner surface of the bladder to the stretch component, projects inwardly into the interior cavity, and partially passes through the plurality of tethers such that the bladder is narrowed at the inwardly projecting tie and the gas in the interior cavity is in fluid communication through the inwardly projecting tie. A method of manufacturing the cushion is also disclosed.
