SYSTEMS AND METHODS FOR DEPLOYING AN IMPLANTABLE MEDICAL DEVICE
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.
ANCHOR MAGAZINES
A catheter device includes a tube, and an extracorporeal unit coupled to a proximal end of the tube. An implant includes a series of anchors and a tether. The series of anchors includes a first anchor and other anchors, arranged along the extracorporeal unit. Each of the anchors includes a tissue-engaging element, and a head that defines an eyelet. The tether extends, along the extracorporeal unit, through the eyelet of each of the other anchors to the first anchor such that (i) the first anchor is advanceable, with a distal end of the tether, distally into and through the tube toward the tissue, and (ii) subsequently, the other anchors are slidable, sequentially, over and along the tether, distally into and through the tube toward the first anchor. Other applications are also described.
METHODS AND DEVICES FOR MANIPULATING AND FASTENING TISSUE
A tissue displacing and fastening device is provided for manipulating and fastening tissue together. The device includes a tissue displacing elements, which displaces tissue. A fold is formed from the displaced tissue and the tissue is fastened together to secure the fold.
Off-Center Tissue Anchors
A tissue anchor system is provided that includes a first tissue anchor, a second tissue anchor that is separate and distinct from the first tissue anchor, and one or more tethers, which are configured to couple the first tissue anchor to the second tissue anchor. When the first tissue anchor is unconstrained, a head thereof is coaxial with an axis of a shaft thereof, and a tissue-coupling element thereof extends from a distal end of the shaft, is generally orthogonal to the axis, and is shaped such that if the tissue-coupling element were to be projected onto a plane that is perpendicular to the axis, at least 80% of an area of a projection of the tissue-coupling element on the plane would fall within a first angle of 180 degrees in the plane having a vertex at the axis. Other embodiments are also described.
Percutaneous clip for repairing a heart valve
Valve repair systems and clips for attachment to one or more leaflets of a heart valve. The clip can include an elongated member configured to be positioned between two leaflets of the heart valve. The elongated member can have a first portion and a second portion that extends from the first portion. A width of the second portion can be greater than the width of the first portion. A pair of arms can be coupled to the first portion and extend toward the second portion. The pair of arms can extend radially away from the elongated member as the pair of arms extend away from the first portion toward the second portion when the arms are in an open position. And the pair of arms can be moveable from the open position to a closed position to pinch each leaflet between one of the arms and the elongated member.
Heart valve docking system
Methods of implanting docking devices for prosthetic valves at a native heart valve include positioning a distal end of a delivery catheter into a first chamber of a heart, advancing a tubular body of a docking device from within the delivery catheter so that the distal end of the tubular body is advanced between native valve leaflets and positioned in a second chamber of the heart. The methods further include inserting a coil into a lumen of the docking device so that the tubular body adopts a configuration, releasing a proximal end of the docking device in the first chamber, inserting a replacement valve in an inner space of the docking device, and radially expanding the replacement valve until there is a retention force between the replacement valve and the docking device to hold the replacement valve in a stable position in the native valve.
Endoscopic needle assembly
A needle and suture assembly is provided for use with an endoscopic suturing device with a needle holder arm. The needle assembly includes a needle tip and a needle body. The needle tip has a sharp end, a capture groove, a tab groove and a plug portion positioned between the capture groove and the tab groove. The needle body has first and second ends, tip tabs, retainers for removably retaining the needle body relative to the needle holder arm, and a suture opening. The needle tip is fixed relative to the needle body by plastic deformation of the tip tabs into the tab groove. A suture extends into the suture opening of the needle body and is fixed therein.
Device, system, and method for transcatheter treatment of valvular regurgitation
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.
Device that can be implanted in a minimally invasive manner and mitral valve implant system
The invention relates in general to the field of heart surgery. In the surgical field, instruments are used in order to examine the interior of living organisms and/or to use for operative interventions. These also include implants for the production of the functionality of a heart. The invention relates to such an implantable device and a method for eliminating regurgitation in the area of the heart. The implantable device is an annuloplasty ring with a large number of tissue anchors. An unfolded annuloplasty ring is positioned in the cavity of a body element in order to constrict a bodily opening. Using the minimally-invasive technique, each tissue anchor of the annuloplasty ring is intravascularly inserted in advance into a precise position on the edge of the mitral valve annulus. The annuloplasty ring that is configured in the shape of an arc or circle is mounted and fastened to the thus anchored fastening means in order to influence in size and shape the septal and lateral annulus of the mitral valve and to close the gap between the anterior and posterior cusps in the valve.
Absorbable surgical coil fastener
A surgical fastener deployment system may include a plurality of coil fasteners having a head and coil body. In some embodiments, the head is comprised of a bioabsorbable polymer. In one embodiment, the coil body may be comprised of a shell and a core and one of the shell and the core may be comprised of one of a magnesium alloy or a bioabsorbable polymer, and the other of the shell and core is formed of the other of the magnesium alloy and the bioabsorbable polymer. The coil body may also include an internal channel which may have a support coil disposed within.
