Knotless suture anchor
A suture anchor comprises a tubular body having an axial bore therethrough and having one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole, such as threads. A lateral port passes through the body from the bore to the exterior surface and is formed of a slot entering the body from its proximal end. A length of suture for attaching soft tissue to bone passes down along the exterior surface over the one or more purchase enhancements, over a distal end of the body, up into the bore through and then back out of the bore and up along the exterior surface over the one or more purchase enhancements.
Prosthetic mitral valve and delivery method
A valve prosthesis and methods for implanting the prosthesis are provided. The prosthesis generally includes a self-expanding frame and two or more engagement arms. A valve prosthesis is sutured to the self-expanding frame. Each engagement arm corresponds to a native mitral valve leaflet. At least one engagement arm immobilizes the native leaflets, and holds the native leaflets close to the main frame. The prosthetic mitral valve frame also includes two or more anchor attachment points. Each anchor attachment point is attached to one or more anchors that help attach the valve prosthesis to the heart.
MINIMALLY INVASIVE SPINAL ANNULUS FIBROSUS REPAIRING DEVICE
The present disclosure provides a minimally invasive spinal annulus fibrosus repairing device, including at least one bone anchor, at least one annulus fibrosus anchor, and at least one suture. The minimally invasive spinal annulus fibrosus repairing device of the present disclosure can be used to repair the annulus fibrosus damage, and can be combined with the use of an annulus fibrosus implant to repair the damaged annulus fibrosus.
Threaded knotless anchor
A knotless suture anchor assembly for engaging a bone tunnel and holding suture therein to knotlessly secure said suture to soft tissue including an elongated generally cylindrical hollow outer member having an axial lumen, an outer surface with projections for engaging the wall of the bone tunnel, a distal end and a proximal end; and an elongated, generally cylindrical inner member having an axis, a proximal end and a distal end, the distal end having a transverse passage for receiving suture therethrough, the transverse passage having a proximal and distal end and adapted to receive a plurality of sutures in said eyelet, the inner member adapted to move coaxially relative to the outer member between a distal, suture-unlocked position and a proximal, suture-locked position.
Ligament fixation system, implants, devices, and methods of use
Devices, systems, implants and methods for achieving ligament fixation are disclosed. An implant includes a head member and an anchor member coupled to the head member. The implant includes tension member that couples the head member to the anchor member. The head member and the anchor member include a cannulation that receives the tension member therein. The implant may include a coupling member positioned between and coupling the head member and the anchor member, the coupling member including a cannulation that receives the tension member therethrough. Insertion instruments for inserting an implant for ligament fixation are also disclosed. Methods of using an implant for achieving ligament fixation are also disclosed.
Anchor delivery systems
Anchor delivery systems include markings on the surfaces of the delivery device which are visually exposed to the user through openings or fenestrations in the anchor, providing visual feedback to the user on the progress of the anchor's insertion. A suture-locking plug is deformable within the anchor tip, thereby enhancing suture entrapment within the tip of the anchor. A compliant component of the handle places the handle components in tension, thereby absorbing built-in axial looseness in the handle. The handle further includes a spin cavity which allows for free spin of the inserter shaft to finalize insertion of the anchor into bone when the anchor has not been fully seated flush with or below the cortical bone surface.
Systems and methods for tissue suspension and compression
Suture passer systems for tissue suspension and tissue compression are described. The system can include a shaft and a needle, wherein the needle is freely rotatable with respect to the shaft. The suture may include an overmolded segment. Methods of placing one or more implants, sutures, fastener, bone anchors and other devices are also described. The methods include moving tissue, including the superior pharyngeal constrictor muscle, palatopharyngeal arch, and palatoglossal arch. The methods include hyoid bone suspension.
HOLLOW TWO-SECTION IMPLANTATION KNOTLESS SUTURE ANCHOR
The present invention pertains to a hollow two-section implantation knotless suture anchor which comprises a main body, a tightening element and a taper. The main body comprises a front part, a rear part, a middle part, a first penetration part, a first accommodation space, a first thread, a tapered structure, and a perforation. The tightening element comprises a second penetration part and a second accommodation space. The taper comprises a taper body and a taper head. Moreover, the suture can pass through the perforation on the outside of the main body through the perforation. Afterthat it can pass through the first accommodation space and then the second accommodation space on the outside of the tightening element from the side of the tightening element opposite to the main body. Finally, it can extend on the outside of the main body. Hence, by pulling the ends of the suture, the tightness of the suture tightened by the tightening element and the front part is adjustable. Also, when the taper body of the first penetration and the second penetration is positioned, the taper head is next to the tightening element. Thus, by rotating the taper, both the main body and the tightening element are rotatable.
METHOD AND APPARATUS FOR SOFT TISSUE FIXATION
A surgical method can include passing at least two adjustable loops of a flexible construct through at least the first tissue to extend from an outer surface of the first tissue opposite a tissue engaging surface facing the second tissue, and attaching the two adjustable loops to a first selected area of the second tissue. The method can further include positioning an elongated locking member within the two adjustable loops such that the locking member extends between the two adjustable loops adjacent the outer surface, engaging the locking member with the outer surface by drawing the two adjustable loops towards the outer surface, and compressing the first tissue between the locking member and the second tissue by tensioning the two adjustable loops. Related tissue fixation devices are also provided.
Tensionable knotless anchors and methods of tissue repair
Surgical devices and methods of soft tissue repair using pre-looped tensionable and non-pre-looped tensionable knotless fixation devices. A flexible material (for example, suture or suture tape) may be attached to the fixation device. A flexible material may be threaded through an eyelet of a tip provided as part of a swivel anchor assembly to provide added stability to the fixation devices.
