Implant for heart valve
An implant includes a clip and a clip-controller interface. The clip is disposed laterally from a central longitudinal axis of the implant, includes first and second arms articulatably coupled to each other, and sandwiches a leaflet of a heart valve between the first and second arms by articulation between the first and second arms, such that the second arm is disposed laterally from the first arm. The clip-controller interface is reversibly coupled to a clip controller of a delivery tool, and includes first and second portions. The first portion is linearly slidable by the clip controller. The second portion is articulatably coupled to the first portion and to the second arm, such that linear sliding of the first portion causes the second portion to (i) articulate with respect to the first portion, and (ii) push the second arm to articulate toward the axis. Other embodiments are also described.
Tricuspid valve repair using tension
A method of reducing tricuspid valve regurgitation is provided, including implanting first, second, and third tissue anchors at respective different first, second, and third implantation sites in cardiac tissue in the vicinity of the tricuspid valve of the patient. The geometry of the tricuspid valve is altered by drawing the leaflets of the tricuspid valve toward one another by applying tension between the first, the second, and the third tissue anchors by rotating a spool that (a) winds therewithin respective portions of first, second, and third longitudinal members coupled to the first, the second, and the third tissue anchors, respectively, and (b) is suspended along the first, the second, and the third longitudinal members hovering over the tricuspid valve away from the annulus of the tricuspid valve. Other embodiments are also described.
Endovascular graft systems and methods for deployment in main and branch arteries
Endovascular systems for deployment at branched arteries include a main tubular graft body deployable within a main artery including a proximal end and an opposed distal end. The proximal and distal ends have a tubular graft wall therein between. A plurality of inflatable channels are disposed along the main tubular graft body, and at least one stent segment is disposed along the tubular graft wall of the main tubular graft body. The plurality of inflatable channels are configured to be inflatable with an inflation medium. The at least one stent segment is disposed between two or more adjacent inflatable channels of the plurality of inflatable channels.
Intraocular lens
The invention is directed to an intraocular lens having an optical body, two haptic elements and first and second sets of a plurality of ropes corresponding to respective ones of the first and second haptic elements. The ropes are secured to the optical body and to the haptic element and have a severing sequence. The haptic elements each have a compressed state, a partly compressed state and an uncompressed state. In the compressed state, the first rope of the severing sequence is configured to deform the haptic element in a direction toward the optical body as a result of which the first rope is under a tensile stress and the rest of the ropes are stress-free and, by the ropes being severed successively in the severing sequence, the haptic element can be brought firstly to the partly compressed state. All the ropes are severed in the uncompressed state.
Stent to assist in arteriovenous fistula formation
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.
URINARY INCONTINENCE AUTOMATIC CONTROL SYSTEM HAVING MULTI-POINT ALTERNATE SWITCHING FUNCTION, AND IN-VIVO MACHINE THEREOF
Disclosed are an automatic control system for urinary incontinence with a function of multi-point switching in turn and an intracorporeal apparatus (200) thereof. The intracorporeal apparatus (200) is completely implanted in a body. The intracorporeal apparatus (200) comprises an intracorporeal microcontroller (220) and urethral blockers (230), the intracorporeal microcontroller (220) being configured to control the urethral blockers (230) to block and unblock the urethra. The intracorporeal apparatus (200) comprises at least two urethral blockers (230) provided at different locations on the urethra, i.e., a first urethral blocker (230a) and a second urethral blocker (230b), and the intracorporeal microcontroller (220) is configured to control the at least two urethral blockers (230) to block and unblock the urethra in turn.
Edentulous specific support and aesthetic restorative appliance
An edentulous mouth insert appliance for mounting upon the edentulous gum of a patient, comprises a u-shaped frame formed of a rigid flexible material, with a portion to embrace the gum and a portion extending beyond the gum with an exposed surface to replicate a bite aligned with the corresponding occlusal plane. The frame has a base supporting a pair of inner and outer side walls spaced apart by the base a distance allowing the frame to encircle and cover the edentulous gum with a space between inner surfaces of the frame and the gum. A fill within the frame fills the space between the frame and the gum upon which the appliance is fitted, providing a void-free seal between the apparatus and the gum.
PROSTHETIC MITRAL VALVE AND DELIVERY METHOD
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.
Transcatheter valve with torsion spring fixation and related systems and methods
Described is a prosthetic valve, comprising: an expandable stent including an inner lumen and having a first and a second end; and a spring attached to the first end of the expandable stent; wherein the expandable stent and the spring can expand radially to a desired diametric configuration in order to anchor the prosthetic valve at an implantation position in a body lumen. Related systems and methods.
