A prosthetic mitral valve has an interior stent and an exterior mesh surrounding the interior stent. The prosthetic mitral valve is released from a capsule and self-expands within a native mitral valve. The exterior wire mesh has a first portion with an enlarged diameter sized for placement above a mitral annulus and a second portion with a reduced diameter for contacting the mitral annulus. Capturing elements are provided on the interior stent. The capturing elements extend in a ventricular direction beyond the exterior wire mesh and then turn in an atrial direction for trapping native mitral leaflets against an outer surface of the wire mesh. A plurality of valve leaflets is provided within the interior stent for replacing the function of the native mitral valve.

A medical device comprises a substrate (10) defining a major surface (9) defining a plane, including a plurality of first struts (14) along a first direction interconnected with a plurality of second struts (12) extending along a second direction not parallel with the first direction, wherein widths (11) of the second struts as measured along the major surface are larger than thicknesses of the second struts as measured perpendicular to the major surface such that when the substrate is stretched in the first direction, intermediate sections (15) of the second struts (12) rotate relative to the first struts (14) and the intermediate sections of the second struts bend out of the plane of the major surface. The medical device is operable to extend and/or retract elements suitable for a particular purpose. The elements are extended and/or retracted in response to a stress applied by way of stretching and/or retracting the device, among other methods. The elements may remain extended and/or retracted or may recoil back to an initial position upon the removal of the force. In various embodiments, the elements are used to treat or deliver treatment to a target site within a body.

Interbody fusion devices including deployable fixation members. The implant may include a spacer, optionally, an end member coupled to the spacer, and one or more fixation members configured to extend into adjacent vertebrae. The fixation members may include screws, nails, shims, tangs, spikes, staples, pins, blades, fins, or the like, and combinations thereof.

In some examples, a delivery device includes a handle that includes a control member, an elongate body, a plurality of arms extending from a distal portion of the elongate body to a distal collar configured to releasably couple to an annuloplasty device. The plurality of arms is operatively coupled to the control member and configured to position the annuloplasty device at a target site in a patient. The delivery device further comprises a plurality of anchors configured to secure the annuloplasty device to tissue at the target site, each respective anchor of the plurality of anchors deployable from a respective arm of the plurality of arms.

There is described an arteriovenous fistula stent, having a tubular body comprising a series of sinusoidal shaped struts along the length of the tubular body. A plurality of curvilinear connectors extend between and are attached to adjacent struts wherein a first end of a connector is attached to a distal face of a proximal strut apex and a second end of a connector is attached to a proximal face of a distal strut apex. A pair of unconnected strut apexes are between pairs of connected apexes. When the tubular body is in a stowed configuration a proximal aperture and a distal aperture are circular and when the tubular body is in a deployed configuration the distal aperture is oblong or ovoid. There is also described a method for inserting a stent for use in creation of an arteriovenous fistula by identifying a candidate artery and a candidate vein and dissecting the candidate vein. Next, inserting a stent into the vein and creating a breach in the candidate artery at a desired angle and location. Next, introducing the stent and vein into the candidate artery and forming the stent into a curvature angle selected to minimize turbulent blood flow in an anastomosis formed by the vein and the artery. Optionally, there is a step of fastening a distal portion of the stent to the artery.

A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

Improvements to devices, systems, and methods for delivering and/or deploying an implantable medical device are described. An implantable medical device may include an annuloplasty ring for implantation on a valve of a patient. Systems and methods may be configured to present graphical user interfaces with device images to implement efficient and accurate implantation of the implantable medical device. The device images may be based on sensor information obtained via sensors associated with the implantable medical device, such as a camera device, a diagnostic imaging device, position sensors, and/or the like. In other aspects, systems and methods may determine optimized configurations for the implantable medical device based on device characteristics including, without limitation, a shape formed by components of the implantable medical device and/or component coordinate information. Systems and methods may operate to facilitate deployment of the implantable medical device to correspond with the optimized configuration. Other embodiments are described.

A prosthetic heart valve for deployment in a native heart valve. The prosthetic heart valve includes an inner frame and a plurality of anchors extending from a distal portion of the inner frame. An outer sealing frame is positioned radially outward of the inner frame. The distal end portion of the outer frame is attached to a distal portion of the inner frame by a flexible cloth material such that the outer frame can move axially or tilt with respect to the inner frame. The anchors are shaped to capture native leaflets between the anchors and the outer frame to secure the prosthetic valve in the native heart valve. Prosthetic valve leaflets are provided in a lumen of the inner frame for allowing one way flow through the prosthetic valve, thereby replacing the function of the native heart valve.

A fixation device for engaging heart valve leaflets includes a center member with a first end, an opposite second end, and a length extending therebetween, first and second arms each having a first free end and an opposite second end, the second end of each arm extending from the second end of the center member, the first and second arms biased in a first position adjacent the center member and moveable to a second position spaced apart from the center member, and an actuator configured to move the first and second arms from the first position to the second position.

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.
