Provided herein are devices and methods for applying a medicament to an eyelid, e.g. eyelid margin, of a patient while protecting the adjunct ocular tissues such as the cornea.

A system includes a core and a catheter for use with (A) a first atrial arm and a first ventricular arm articulatable with respect to each other at a first articulation site to clamp one leaflet of a patient's native heart valve, and (B) a second atrial arm and a second ventricular arm articulatable with respect to each other at a second articulation site to clamp another native leaflet of the native valve. The core tapers in a distal direction toward its smallest perimeter, defining a minimum nonzero angle of the atrial arms with respect to a central longitudinal axis of the core. The catheter advances the core and the arms toward the native valve. The catheter and the core have an advancement configuration in which the smallest perimeter of the core is adjacent to the first and second articulation sites. Other embodiments are also described.

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.

A prosthetic heart valve including a frame, leaflet structure, and sealing member disposed around an outer surface of the frame is disclosed. As one example, the sealing member includes an inner layer and a plush outer layer comprising a plush outer surface. The inner layer is arranged against the outer surface of the frame and the outer layer is arranged against and attached to the inner layer. The inner layer is folded over at inflow and outflow ends, in an axial direction relative to a central longitudinal axis of the frame, to overlap respective ends of the outer layer and form tapered folds at opposite ends of the sealing member, each tapered fold including a narrower, first portion where the inner layer folds over and contacts itself and a wider, second portion where the inner layer overlaps an outer surface of an end portion of the outer layer.

A prosthetic mitral valve with improved blood flow to the left ventricular outflow tract (LVOT). The prosthetic mitral valve includes an expandable outer stent having an atrial end and a ventricular end, and an expandable inner stent attached to and at least partially positioned within the outer stent. The inner stent has an inflow end, an outflow end and a connector securing a tether. A valve assembly including a cuff and a plurality of leaflets may be disposed within the inner stent. The outer stent is expandable from a delivery condition in which the outer stent is axially elongated to a deployed condition in which a first portion of the outer stent is folded upon a second portion of the outer stent to define a flange for engaging an atrial surface of a native valve annulus and to stabilize the prosthetic heart valve within the native valve annulus.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

A device for treating a diseased native valve in a patient includes a frame structure and a valve segment coupled to the frame structure. The frame structure has an unexpanded configuration and an expanded configuration. The valve segment has a plurality of leaflets, a seal, and a seal support. An inflow edge of the plurality of leaflets is unsupported by the frame structure. The seal is attached to the inflow edge of the plurality of leaflets and positioned radially between the frame structure and the plurality of leaflets. The seal support is attached to or within the seal and provides axial rigidity to the seal.

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.

A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end, the stent including a plurality of struts. A cuff may be coupled to the stent so that a flat, bottom edge of the cuff lies adjacent the proximal end of the stent. A pattern of stitches may be circumferentially disposed around the flat bottom edge of the cuff, the pattern of stitches alternating between stitches sewn to the cuff only and stitches sewn to both the cuff and the stent.

An implantable prosthetic device can include a frame movable between a radially compressed and a radially expanded configuration and a sealing member. The frame can include an inflow end portion, an outflow end portion, and a plurality of struts. The sealing member can be disposed around the frame and can include a cushioning layer comprising a plurality of texturized yarns extending along the longitudinal axis of the frame, and a base layer disposed between the cushioning layer and the frame.
