IMPLANT FOR HEART VALVE
A heart valve repair system includes a delivery sheath and an implant that includes a frame having a surface configured to contact an upstream surface of a native heart valve. First and second gripping members are coupled to the frame and each (1) includes first and second arms and (2) is configured to clamp a respective native leaflet. The implant is disposed in the sheath in a delivery state in which the frame defines a wall fully surrounding a central longitudinal axis of the implant. The distal end of the wall defines a distal opening of the frame. The distal end of the wall is disposed proximally to the entire first tissue-engaging surface of each of the gripping members and proximally to the entire second tissue-engaging surface of each of the gripping members. Other embodiments are also described.
Endovascular prosthesis delivery device
There is described an endovascular prosthesis delivery device. The subject endovascular prosthesis delivery device comprises a combination of a delivery frame element and a hub insert element that are secured to one another by a first retention element. At a distal portion of the delivery frame element, there is a prosthesis attachment zone for coupling to an endovascular prosthesis. When it is desired to deploy the endovascular prosthesis, the first retention element is broken in a manner to allow relative movement between the hub insert element and the delivery frame element. A pull wire assembly is secured with respect to the hub insert element and comprises a pull wire which is coupled to the endovascular prosthesis in the prosthesis attachment zone of the delivery frame element. Once the first retention element is broken by the physician (this is done when the endovascular prosthesis is in the correct position for deployment), the physician can then retract the hub insert which has the effect of retracting pull wire from the prosthesis attachment zone of the delivery frame element. The endovascular prosthesis and the endovascular prosthesis delivery device are now detached from one another and the latter may be withdrawn from the patient.
DEVICE FOR SECURING HEART VALVE LEAFLETS
A heart valve prosthesis is provided that includes a first member and a second member. The first member comprises a first central portion to be disposed adjacent to a line of coaptation on a first side of two adjacent heart leaflets and peripheral portions to be placed into direct contact with the two adjacent heart leaflets. The second member is separate from or can be separable from the first member, for example during delivery. The second member has a central portion and peripheral portions configured to be placed into direct contact with a second side of the two adjacent heart leaflets.
CARDIAC VALVE REPAIR DEVICES WITH ANNULOPLASTY FEATURES AND ASSOCIATED SYSTEMS AND METHODS
Cardiac valve repair devices with annuloplasty features and associated systems and methods are disclosed herein. A cardiac valve repair device configured in accordance with embodiments of the present technology can include, for example, an atrial fixation member configured to engage tissue within a left atrium proximate to a native mitral valve and a spring mechanism coupled to an inferior edge portion of the atrial fixation member. The spring mechanism has an extended state with a first length corresponding to a dimension of the atrial fixation member in a deployed state and a relaxed state with a shorter length corresponding to a desired dimension of the native valve annulus. When implanted, the spring mechanism contracts the atrial fixation member such that the native mitral annulus anchored to the atrial fixation member reduces in a cross-sectional dimension.
OSTIAL STENTING UNDER VISION
A system comprising a stent and a stent delivery device configured with a tiny intravascular ultrasound (“IVUS”) transducer on the tip of a delivery catheter which can image the interior of blood vessels. Methods for treating ostial or bifurcated lesions using the system.
METHODS AND APPARATUS FOR PLAQUE DISRUPTION
Balloon catheters, sleeves, cages, and endoluminal prostheses are provided with stress-applying and spacing features coupled to expandable surfaces thereof. The stress-applying features may have blunt and/or rounded contact regions which contact tissue or calcified regions in the vasculature. The contact regions dent or fracture occlusive material on the wall of a vascular lumen and/or patient valve leaflets when expanded. The spacing features permit blood, drug, and contrast perfusion past structures expanded in the vasculature, particularly balloon catheters.
TORIC SMALL APERTURE INTRAOCULAR LENS WITH EXTENDED DEPTH OF FOCUS
An intraocular lens is provided that includes a refractive element and a mask. The refractive element has a first power in a first meridian and a second power greater than the first power in a second meridian. A magnitude of the first and second powers and a location of the first and second meridians are configured to correct astigmatism in a human eye. The mask is configured to block a substantial portion of light from passing through an annular region thereof and to permit a substantial portion of light to pass through a central aperture thereof to enhance an astigmatism correction rotational misplacement range and depth of focus.
VASCULAR IMPLANT
A medical implant (20) includes first and second ring members (22, 24), each including a resilient framework (26) having a generally cylindrical form. A tubular sleeve (28) is fixed to the first and second ring members so as to hold the ring members in mutual longitudinal alignment, thereby defining a lumen (32) passing through the ring members. A constricting element (30) is fit around the sleeve at a location intermediate the first and second ring members so as to reduce a diameter of the lumen at the location.
DRAIN-COMPATIBLE TISSUE EXPANSION DEVICE
A drain-compatible soft tissue expander can incorporate a drainage structure that allows fluid to be removed from the body of a living subject. The soft tissue expander can include an expandable shell and a drainage structure that can, for example, assist in mitigating or eliminating seromas. The drainage structure can be coupled to the shell at a plurality of locations and be removable therefrom without damaging the expandable shell.
STENT
The present invention relates to a stent for transluminal implantation into hollow organs, in particular into blood vessels, ureters, esophagi, the colon, the duodenum, the airways or the biliary tract, comprising an at least substantially tubular body that extends along a longitudinal direction and that can be converted from a compressed state having a first cross-sectional diameter into an expanded state having an enlarged second cross-sectional diameter, wherein the stent comprises a stent body composed of a biostable material, characterized in that the stent body comprises a plurality of stent sections, preferably annular stent sections, that are in particular separate from one another, and the stent has a support structure that connects the stent sections to one another, wherein the support structure is formed from a bioresorbable material or comprises a bioresorbable material.
