  • Publication number: 20250213244
    Abstract: A method of suturing an opening in a target tissue can comprise stitching a first suture to a first pad, stitching the first pad to a first tissue area adjacent to the opening in the target tissue and stitching a second suture to the first pad. The method can include forming a first purse-string suture, using the first suture, along a first path in the target tissue around the opening using the first suture, and forming a second purse-string suture, using the second suture, along a second path in the target tissue surrounding the first purse-string suture.

  • Publication number: 20250186209
    Abstract: Disclosed herein are sutures (or cords) and methods for using sutures wherein the sutures comprise a material or a combination of materials configured to increase echogenicity of the sutures. In some examples, the sutures comprise echogenic materials incorporated into suture material (e.g., ePTFE). In some examples, the sutures comprise a combination of materials with abrupt and relatively large changes in density to increase reflections of ultrasound waves. The disclosed sutures enhance echogenicity to increase visibility of the sutures using ultrasound imaging technologies. Furthermore, disclosed herein are methods that utilize the disclosed sutures in valve repairs including implanting artificial cords, sub-valvular techniques, reshaping organs, annuloplasty, and the like. Utilization of the disclosed echogenic sutures can result in superior outcomes due at least in part to physicians being able to better visualize the placement and/or tension of the echogenic sutures.

  • Patent number: 12256920
    Abstract: A method of suturing a tissue opening can comprise placing a tissue-facing surface of a first pad, a second pad and a third pad over respective tissue areas adjacent to the tissue opening. The second pad can be positioned on a first side of the first pad and the third pad can be positioned on a second side of the first pad. The first and second pads can be coupled to a suture, the suture forming a stitch over the upper surface of each of the respective pads. The suture can be stitched through an area of tissue between the first pad and the second pad, between the second pad and the third pad, and between the third pad and the first pad. A first distal portion and a second distal portion of the suture can be coupled to the third pad for forming the purse-string suture.

  • Publication number: 20250090323
    Abstract: An annuloplasty ring for repair of mitral valves whose shape can be altered directly or remotely to perform post-implant size and/or shape adjustments. One version of the annuloplasty ring has a size-adjustable remodeling inner core within an outer suture-permeable interface for attaching the ring to an annulus. The inner core has a size-adjustable segment formed by short spaced-apart tubular sections that can move toward and way from one another such as on rails. Alternatively, short sections separated by compressible connectors may be used. One or more tethers may be attached to one side of the size-adjustable segment and pulled from the other side to constrict the segment. Multiple tethers may be connect at different locations around the ring to provide some control over where the ring constricts. An adjustment handle with a flexible shaft may be operated from outside the body to adjust the ring post-implant.

  • Patent number: 12201525
    Abstract: A tissue anchor delivery device includes a handle, an elongate shaft extending from the handle, a pusher tube disposed at least partially within a lumen of the elongate shaft, a pusher hub coupled to the pusher tube, a needle disposed at least partially within a lumen of the pusher tube, a needle hub coupled to the needle, and an actuator configured to be fixed to the pusher hub and the needle hub. The actuator is further configured to advance the needle hub and the pusher hub a first distance, thereby causing a tip of the needle to protrude from a distal end of the elongate shaft, disengage from the needle hub, and advance the pusher hub a second distance relative to the needle hub, thereby causing a distal end of the pusher tube to advance over the needle and push a coiled suture form off of the needle.

  • Publication number: 20240303817
    Abstract: Techniques relate to analyzing image data to determine an annuloplasty ring to implant for an annuloplasty procedure. For example, image data can be received that depicts a heart valve. The image data can be analyzed to identify one or more image features that represent one or more anatomical features of the heart valve. Based on the one or more image features, heart data can be generated that indicates a measurement and/or another characteristic of the heart valve. An annuloplasty ring can be determined based on the heart valve data and/or annuloplasty ring data indicating characteristics of one or more annuloplasty rings. User interface data can then be generated that indicates the annuloplasty ring.

  • Publication number: 20240225840
    Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.

  • Publication number: 20240173034
    Abstract: Systems, apparatuses, and methods disclosed herein may be directed to clips for medical implementation, including clips for a portion of a heart. The clips may be configured to close the portion of the heart, to reduce blood flow therethrough as well as passage of clots or other undesired materials. In examples, the clips may be configured to close the left atrial appendage (LAA). The closure of the LAA may reduce the possibility of stroke or other maladies stemming from fluid flow with the LAA. In examples, the clips may be positioned exterior of the LAA, to extend over an outer surface of the LAA for closure.
