    Abstract: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

    Abstract: Disclosed herein are designs for improved inflatable structures for use during minimally invasive cardiovascular procedures. These inflatable structures facilitate the perfusion of blood through an anatomical structure, such as a heart valve, during the cardiovascular procedure. The inflatable structures are formed of a plurality of balloons arranged radially around a central location. The plurality of balloons form a lumen through which blood flows. Each balloon of the plurality is shaped or configured to stabilize the adjacent balloons, limiting their movement relative to each other. For example, some embodiments can feature balloons with a keystone shape that limits movement of the balloons inward toward the lumen. Some implementations can also include a support coil running through the lumen. The support coil holds enables the lumen to be open to perfusion even in the early stages of balloon inflation.

    Abstract translation: 本文公开了用于在微创心血管程序中使用的改进的可充气结构的设计。 在心血管手术过程中，这些充气结构有助于通过解剖结构（例如心脏瓣膜）灌注血液。 可膨胀结构由围绕中心位置径向排列的多个气球形成。 多个气球形成血液流过的内腔。 多个的每个气囊被成形或构造成稳定相邻气球，限制它们相对于彼此的运动。 例如，一些实施例可以具有限制气囊朝着内腔向内移动的梯形形状的气球。 一些实施方案还可以包括穿过管腔的支撑线圈。 即使在球囊充气的早期阶段，支撑线圈支架也能使内腔开放以灌注。
