Abstract
Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. The invention provides an implant system having multiple anchors, e.g., one or more posterior anchors in combination with one or more anterior anchors. Methods of deploying such anchors, and use of multiple anchors or multiple bridging elements are also provided.
Claims38
An anchor system comprising:
- a) an augmentation device having an elongated cylindrical body, the augmentation device having an elongated lumen defined by a substantially cylindrical wall, the lumen being configured to receive an anchor, wherein the cylindrical wall includes one or more slots disposed along a length of the cylindrical body for engaging a bridging element of the anchor;
- and
- b) an anchor having a substantially cylindrical body that is sized to pass within the elongated cylindrical body of the augmentation device and a bridging element coupled to an intermediate portion of the anchor.
An anchor system comprising:
- a) an augmentation device having an elongated shaft body, wherein the shaft body has a first elongated configuration and a second flexed configuration, wherein the second flexed configuration has a reduced length as compared to the first elongated configuration;
- and
- b) an anchor having a substantially cylindrical body having a length less than the that of the augmentation device, and a bridging element coupled to an intermediate portion of the anchor, wherein the system is configured such that when the augmentation device and anchor are coupled and deployed in a body lumen, a force upon a wall of the body lumen from the anchor is translated to the augmentation device to deform the wall.
An anchor system comprising:
- a) an anterior anchor having an anchor portion operable to secure the anterior anchor in tissue, a through hole extending through the anchor member, and an elongated tube having a lumen coextensive with the through hole, wherein the elongated tube is composed of a semi-rigid or rigid material that resists flexing;
- and
- b) a posterior anchor coupled to a first end of a bridging element, wherein a second end of the bridging element is configured to traverse the lumen of the elongated tube of the anterior anchor.
An anchor system comprising:
- a) an anterior anchor having an anchor portion operable to secure the anterior anchor in tissue, a through hole extending through the anchor member, and an adjustable arm extending from the anchor portion;
- and
- b) a posterior anchor coupled to a first end of a bridging element, wherein a second end of the bridging element is configured to traverse the through hole of the anterior anchor, and wherein the adjustable arm is operable to adjust positioning of the bridging element when the anterior anchor and the posterior anchor are coupled via the bridging element upon deployment in a body vessel.
An anchor system comprising:
- a) an anterior implant having a first anterior anchor, a second anterior anchor, a connecting rail extending between the first and second anterior anchors, and a bridging element connector disposed on the connecting rail;
- and
- b) a posterior anchor coupled to a first end of a bridging element, wherein a second end of the bridging element is configured to engage the bridging element connector and traverse a through hole of the first anterior anchor or a through hole of the second anterior anchor when the anterior implant and the posterior anchor are coupled via the bridging element upon deployment in a body vessel.
