Abdominal closure method and device variations for closing ventral hernias and reducing recurrence
A combined magnetic and bioabsorbable device for ventral hernia closure and/or tension distribution for maintenance of tissue apposition for healing, while avoiding a long-term footprint of foreign material and precluding materials spanning the interior layer of the abdominal closure where risk to visceral structures exists.
Knotless closure sutures and methods of tissue fixation
Surgical suturing constructs, suture anchor assemblies, and methods of tissue fixation are disclosed. The suturing construct includes a bumpy suture. A suturing construct may include one or more small loops on a distal end. A suturing construct may include a splice terminating into a tapered portion/region at a proximal end. A bumpy suture of a suturing construct may form a knotless, closed, self-locking loop around tissue.
Self-cinching suture anchors, systems, and methods
Various self-cinching suture anchors, self-cinching suture anchor systems, and methods of use are provided. In one exemplary embodiment, a suture anchor is provided that includes an outer member and an inner member configured to be received within the outer member. The inner and outer members can define a gap that allows a suture to be movably disposed within the outer member, e.g., within the gap, when the inner member is disposed within the outer member. The inner member can be configured to be secured within the outer member by a knot of the suture having a diameter greater than a width of the gap so as to fix the inner member within the outer member, while still allowing uni-directional tensioning of the suture.
Indirect attachment of a needle to a mesh suture
A medical device includes a surgical needle, an elongated suture, and an intervening segment. The elongated suture has a first end proximate to the needle and a second end located away from the needle. The elongated suture also includes a plurality of fibers defining a mesh wall between the first and second ends. A plurality of pores extend through the mesh wall, at least some which are in the macroporous size range of greater than 200 microns for facilitating tissue integration when introduced into a body. The intervening segment is disposed between and connected to either or both ends of the elongated suture and the needle. The intervening segment includes one or more fibers of the plurality of fibers and has a cross-sectional dimension smaller than a cross-sectional dimension of the mesh wall such that the intervening segment facilitates indirect attachment of the elongated macroporous mesh suture to the needle.
SUTURE PASSER SYSTEMS AND METHODS FOR TONGUE OR OTHER TISSUE SUSPENSION AND COMPRESSION
Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.
Apparatus for manipulating and securing tissue
Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.
Active tension bone and joint stabilization methods
Methods of use for bone and joint stabilization devices are described in which the devices are tensioned after anchoring during a medical procedure and remain active in maintaining axial tension for continued compression of the subject anatomy.
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.
Medical device for wound closure and method of use
A medical device for wound closure, e.g., repairing perforations and tissue wall defects. The medical device has a barbed elongate body and an outer member. The medical device may further include a foam structure. The medical device may also include an inner member which may be a tissue scaffold. A method for closing tissue is also disclosed.
Knotless suture anchor and methods of use
Various devices, systems and methods for knotless suturing of tissue are disclosed. These devices allow sutures to be anchored to bone, and more specifically provide a suture anchor which eliminates the need for knotting the suture. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts may be suited to being a single molded polymer construction. The anchors will find particular utility in hip and shoulder arthroscopy, e.g. labral re-attachment and similar procedures.
