TISSUE AUGMENTATION TACKS FOR USE WITH SOFT TISSUE FIXATION REPAIR SYSTEMS AND METHODS

Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture, and can be useful in many different tissue repair procedures that are disclosed in the application. In one exemplary embodiment, one or more constructs are disposed on a suture threader, which can be used to associate the construct(s) with a repair suture(s) being used to repair the soft tissue. Tissue augmentation constructs can include various blocks and patches, among other formations. Exemplary methods for manufacturing the tissue augmentation constructs are also provided.

Methods and devices for ligament repair

Devices and methods are provided for positioning and forming bone tunnels. In one embodiment, a surgical drill guide apparatus is provided. The apparatus can include a first guide member having a longitudinal passageway extending therethrough for aiming a first guide pin along a first path to form a first bone tunnel. The apparatus can also include a second guide member having a longitudinal passageway extending therethrough for aiming a second guide pin along a second path to form a second bone tunnel. The first and second guide members can extend at an angle relative to one another and they can be offset such that axes of the guide members do not intersect.

Device for placing bore channels when attaching artificial ligaments to the bone and method for producing a corresponding device
09811609 · 2017-11-07 ·

A device for the patient-specific, individual anatomic placement of bore channels when attaching artificial ligaments to bones, namely for use in placing boreholes on the thigh and lower leg during anterior cruciate ligament reconstruction, is provided with a probe (1) to be introduced into a joint via an arthroscopy portal and with a targeting head (2) disposed on the distal end of the probe. The targeting head (2) comprises a targeting template (3) which is produced individually using a 3-D imaging method, in particular 3-D magnetic resonance tomography (3-D-MRT) or 3-D computer tomography (3-D-CT), and which is a negative imprint of the osseous surface relief in the region where the torn ligament attaches to the bone in question, in particular where the cruciate ligament attaches to the thigh or lower leg. The targeting template (3) comprises at least one passage (4) for marking the bore channel that is to be produced on the bone, and a hand grip (7) is provided on the proximal end of the probe (1) for holding and positioning. The invention also relates to a method for producing a corresponding device.

Arthroscopic tenodesis tool
11246700 · 2022-02-15 ·

An arthroscopic tenodesis kit, includes a guide including an elongate member having a length with a distal portion having one or more spring arms configured to open toward a free end of the distal portion of the guide to directly and releasably engage a tendon. The kit also includes an inserter having an elongate cannulated body having an interior bore having a blind end and an open end configured to slidingly receive the guide. The body of the inserter has a length that is shorter than the length of the guide, so that the distal portion of the guide remains spaced from the bore when the guide is fully received within the bore.

Tendon Repair Implant and Surgical Instruments for Tendon Repair
20220039942 · 2022-02-10 ·

A tendon repair implant and related surgical instruments are disclosed. The tendon repair implant has an elongated substrate with a convex side and a concave side with a plurality of spikes protruding from the concave side at an angle that optimally retains a. tendon to the bone that the tendon repair implant is subsequently attached to. A surgical retainer for the tendon repair implant is also provided that releasably retains the tendon repair implant during surgery and implantation, A drill guide instrument for the tendon repair implant Is also provided that allows the surgeon to precisely place fastening holes in the bone prior to implantation of the tendon repair implant.

TARGET APPARATUS FOR ALIGNING A SURGICAL DRILLING INSTRUMENT

A target apparatus for aligning a surgical drilling instrument that includes a pointer mechanism for arranging at a location on a bone where a drilled hole that is to be formed is intended to emerge, a guide mechanism for guiding the surgical drilling instrument, and an adjustable connection mechanism with a first end, which is connected to the guide mechanism, and a second end, which is connected to the pointer mechanism. The adjustable connection mechanism comprises a first component, a second component and a locking mechanism. The second component is movable relative to the first component along a predetermined path. The first component is elastically deformable by the locking mechanism such that the second component can be locked relative to the first component by clamping.

Glenoid anchor guide
11369391 · 2022-06-28 · ·

A guide provides for placing a suture anchor into an outer rim of a glenoid cavity of a patient adjacent an edge of a glenoid labrum. The guide comprises an elongated guide tube having an axial lumen with a distal opening a rim engagement member pivotally attached to the elongated tube adjacent the distal opening. The rim engagement member has a first contact surface and a second contact surface each of which are distal of the guide tube and are separated from each other and disposed on opposite lateral sides of the guide tube whereby to allow placement of the contact member over the glenoid rim, with subsequent angular positioning of the guide tube and passage of an instrument down the lumen to the labrum.

Alignment apparatus for use in surgery

An apparatus comprising: a medical tool moveable to a desired orientation relative to a bone region for implantation of a medical implant; and an electronic orientation sensor transitionable between a first location fixed relative to the bone region of the patient and a second location on the medical tool; wherein, at the first location, the orientation sensor is adapted to record a reference orientation of the bone region of the patient, and, at the second location, the orientation sensor is adapted to determine an orientation of the medical tool relative to the reference orientation, wherein recording the reference orientation comprises measuring a gravity vector relative to the orientation sensor.
