A medical device and method of use comprising a base portion having a length extending from proximal end and a distal end and a width extending from a first side to a laterally opposed second side. At least one arm extending from at least one of the first or second sides, the at least one arm extending a distance greater than the width of the base portion. The arm being configured to extend around at least a portion of a cervical isthmus.

A crosslink is provided for securing orthopedic implants, such as facet joint replacement implants, together. The crosslink has a pair of implant coupling components, a pair of rod coupling components, a rod, and a pair of fasteners. Each facet joint implant may include a semicylindrical interface received in a resilient member of the corresponding implant coupling component to permit relative cephalad/caudal adjustment between the crosslink and the implants. The resilient members grip the semicylindrical interface of the implant to enable at least temporary attachment of the implant coupling components to the implants independently of the rod. Clocking features on the semicylindrical interfaces and on the interfacing areas of the implant coupling components and rod coupling components may limit assembly of the crosslink to discrete relative orientations and prevent play after assembly. The fasteners secure the rod coupling components to the rod at the desired positions along the rod.

A system for implanting an interbody device between adjacent vertebrae comprises an interbody device having a plurality of lobes extending outwardly from a longitudinal rib, and having a relaxed shape approximating the shape of the disc being replaced. An insertion guide has a bore therein from a proximal end to a distal end thereof to accept the interbody device in an unrelaxed shape. The distal end is shaped for insertion into an intervertebral space. The insertion rod may be positioned within the bore of the insertion guide whereby the interbody device is positioned within the intervertebral space by advancing the insertion rod into the insertion guide.

An expandable interbody spacer (10) is provided that includes a pair of oppositely facing endplate components (20, 40) and an interior component that includes one or more vertically extending stacks of arranged C-clip members (70) radially surrounding one or more bosses (30) protruding interiorly from one of the endplates, wherein the size and configuration of the bosses and the C-clip members are designed to allow the incremental expansion of expandable interbody spacer.

An implantable medical device for transcatheter delivery, which includes an anchor unit (100) configured to be anchored at an annulus of a cardiac valve of a patient, at least one coupling unit (200) that extends along a first length radially from said anchor unit (100) towards a coaptation line of said valve and including an extension unit (400) extending along a second length. The extension unit (400) is configured to cross between the leaflets of the cardiac valve in order to fill out for an insufficient closing of the valve leaflets of said cardiac valve.

Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. In some examples, a delivery apparatus can include a first shaft configured to rotate around a central longitudinal axis of the delivery apparatus to rotationally align a prosthetic valve mounted on the delivery apparatus with native anatomy, a second shaft extending through the first shaft and having a distal end portion extending distally beyond a distal end portion of the first shaft, an inflatable balloon coupled to the distal end portion of the first shaft, and a distal shoulder mounted on the distal end portion of the second shaft and arranged within a distal end portion of the balloon. The distal shoulder comprises a base portion and a flared portion that extends radially outward from the base portion, and a radiopaque marker is disposed on the flared portion.

An implant and method for repairing and/or replacing functionality of a native mitral valve are in various embodiments configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor can be used to implant a prosthetic valve in a native mitral valve of a heart. The coiled anchor can include a plurality of ventricular turns and one or more atrial turns. The coiled anchor is configured to be implanted at the native mitral valve with the plurality of ventricular turns positioned in a left ventricle of the heart and around valve leaflets of the native mitral valve. The plurality of ventricular turns are configured such that when a radially outward pressure is applied to at least one of the plurality of ventricular turns, the coiled anchor is biased such that a first diameter of a first turn of the plurality of ventricular turns is expanded and a second diameter of a second turn of the plurality of ventricular turns is reduced.

A remotely-activated injection device for use in vertebroplasty is provided to inject a flourescent probe material into a patient. The injection device includes a pump defining an injection chamber having an exit opening; an actuator; and a cable having a first end coupled to the actuator, and a second end remotely engaging the pump. The actuator remotely controls the pump by responsive movement of the cable to thereby cause injection of a flourescent probe material from the injection chamber of the pump through the exit opening to the patient.

A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.

Embodiments described include devices and methods for forming a porous polymer material. Devices disclosed and formed using the methods described a spacer for spinal fusion, craniomaxillofacial (CMF) structures, and other structures for tissue implants.
