Abstract: A side-deliverable prosthetic heart valve includes an outer frame and a flow control component. The outer frame has a supra-annular region, a subannular region, and a transannular region therebetween. The flow control component is mounted to the outer frame such that at least a portion of the flow control component is disposed in the transannular region. The prosthetic valve has a delivery configuration for side-delivery via a delivery catheter and is expandable when the prosthetic valve is released from the delivery catheter. The subannular region of the outer frame is disposable in a first configuration as the prosthetic valve is seated in an annulus of a native heart valve and is transitionable to a second configuration after the prosthetic valve is seated in the annulus of the native heart valve.

Abstract: An ophthalmic implant for drug delivery. The implant includes a primary intracapsular device coupled to a secondary device, wherein, when implanted in a patient's eye, the primary intracapsular device is held in place by the patient's capsular bag and the secondary device is held in place by the primary intracapsular device. The implant may be inserted in the eye by injecting the primary intracapsular device into the eye either before or after attaching the secondary device to the primary intracapsular device, and subsequently positioning the joined secondary device and primary intracapsular device with the primary intracapsular device held in place by the patient's capsular bag and the secondary device held in place by the primary intracapsular device. The secondary device may be designed to hold a tertiary device that can be implanted and attached at the time of surgery or anytime postoperatively.

A plurality of levers are in jointed connection with: the anterior floating lens unit at respective first longitudinal sites along the levers, the anterior rim complex at respective second longitudinal sites along the levers, and the posterior lens unit at respective third longitudinal sites along the levers. The respective second longitudinal sites are longitudinally between the respective first and the respective third longitudinal sites. The levers are arranged (a) such that the third longitudinal sites serve as respective fulcrums for the plurality of levers, and (b) to move the anterior floating lens unit toward and away from the anterior rim complex, in the anterior-posterior direction. Other embodiments are also described.
Abstract: An artificial valve for implantation in a mammal body, in or adjacent to a mammal blood vessel, the artificial valve comprising a casing and a closing mechanism, with at least part of said closing mechanism being a first moving part adapted to make movements relative to said casing. The movements are movements to assume a fully open and a fully closed position for opening and closing, respectively, the blood flow through said blood vessel, as well as at least one position in between said fully open and fully closed positions. The first moving part is adapted to receive energy for at least one of its movements at least in part from an energy device which is also comprised in the artificial valve and arranged to be placed external to said blood vessel.

Abstract: The present technology is directed to an adjustable power intraocular lens comprising a container, an optical fluid in the container, and a transport substance in solution with the optical fluid. The container has an optical component and a peripheral component extending around at least a portion of the optical component. The optical component has an anterior optical element, a posterior optical element, and a fluid chamber having a chamber volume between the anterior optical element and the posterior optical element. The transport substance is configured to pass through the container. The adjustable power intraocular lens further comprises volume control elements in the container. The volume control elements are configured to be activated by a non-invasive energy and upon activation release the transport substance into the optical fluid to decrease the chamber volume and/or absorb the transport substance from the optical fluid to increase the chamber volume.

Abstract: The devices and methods of the present invention provide a means to depress the sclera in such a fashion as to provide single point, multiple point, semicircular or 360° circumferential scleral tissue depression without the need for manual manipulation of the scleral depressor. The device comprises a shaped depressor for insertion between the sclera and the orbit of the eye and a holding means for positioning the depressor. In some embodiments the device can be integrated with a speculum. Use of the device eliminates the need to have a second person manipulate the depressor during the procedure and directly enables bimanual surgery.
Abstract: A drug-eluting stent whose main body is made of a metal or a polymeric material, the surface of which is coated with a mixture including cilostazol and a bioabsorbable polymer, wherein the molecular weight of the bioabsorbable polymer is 40,000 to 600,000.
Abstract: The disclosure provides a method for selecting toric intraocular lenses (IOL) and relaxing incision for correcting refractive error. The one or more toric IOL and relaxing incision combinations can be used for off-axis correction of refractive errors such as astigmatism. The disclosure provides a method for selecting toric IOL and relaxing incision combinations that have combined astigmatism correcting powers and off-axis positions or orientations of the astigmatism correcting axes of the toric IOL and relaxing incision that are effective to yield lower residual astigmatism than on axis correction methods. The toric IOL and relaxing incision combinations also allow the user to avoid incisions that will radially overlap with a cataract incision thereby provided improved outcomes.

Abstract: Apparatus and methods are described for treating a subject with a diseased mitral valve. A docking element (100) is implanted within the subject's left atrium such that no portion of the docking element extends through the subject's mitral valve. The docking becomes anchored to tissue of the left atrium at least partially via ingrowth of the tissue of the left atrium. The docking element (100) includes a ring (102), which is implanted at the subject's mitral valve annulus, and a frame (104), having a height of at least 15 mm, which extends upwardly from the ring. A prosthetic mitral valve apparatus (20) is placed at least partially inside the docking element subsequent to the ingrowth of the tissue of the left atrium having occurred, and becomes anchored to the docking element, at least partially by radially expanding against the ring. Other applications are also described.
