Haisco Pharmaceutical Group has been granted a patent for an implantable annuloplasty system. The system involves deploying multiple members and anchors to the mitral valve annulus in the left atrium of the heart. Tension is applied to flexible tensile members to bring the anterior and posterior sides of the annulus closer together. The system can be deployed through a catheter.

A recently granted patent (Publication Number: US11672661B2) describes an implantable annuloplasty system designed to treat mitral valve annulus conditions in the heart. The system consists of multiple components, including a first member, a second member, and a third member, each with their respective anchors. The first member is anchored to the anterior side of the mitral valve annulus, while the second member is anchored to the posterior side. The third member is also anchored to the anterior side.

The system utilizes two flexible tensile members to bring the anterior and posterior sides of the mitral valve annulus closer together. The first tensile member spans between the first and second members, while the second tensile member spans between the second and third members. These tensile members can be independently tensioned to draw the respective members towards each other, facilitating the approximation of the anterior and posterior sides of the mitral valve annulus.

The second member is elongated and may have slits to allow for flexibility. It can also take on a curved shape. Additionally, the second member features extended features on opposite ends that engage with the tensile members. An anchor guide is mounted to the second member to guide the second member anchor into heart tissue. The anchor guide can fold flat against the second member for easy loading into a catheter.

The system may also include hinges on the second member, enabling it to be foldable along discrete hinge axes. Leads can be attached to each of the first, second, and third members. The first tensile member is attached to the first member, and the second tensile member may be attached to the third member. Notably, there is no tensile member spanning between the first and third members.

Furthermore, portions of the flexible tensile members are configured to pass directly over the mitral valve opening. This configuration allows the system to be deployed into the left atrium of the heart through a catheter.

Overall, this patent describes an implantable annuloplasty system with various components and features that enable the approximation of the anterior and posterior sides of the mitral valve annulus. The system offers potential benefits for treating mitral valve annulus conditions and may provide improved outcomes for patients.
