A medical device packaging system that includes a medical device packaged within an outer sleeve with an open end and a closure flap for closing an end opposite the open end. The packaging system further includes a seal that couples the closure flap to the outer sleeve to close the end opposite the open end. The seal is frangible along an edge between the closure flap and outer sleeve. The packaging system further includes an inner sleeve with a corresponding shape to the outer sleeve, and the outer sleeve and the inner sleeve are configured to move relative to each other in a longitudinal direction of the sleeves. The packaging system further includes a stiffener with a leading edge disposed within the inner and outer sleeves such that the leading edge of the stiffener is configured to interact with an inner surface of the closure flap.

A gastrointestinal system includes a bracelet type anchor constructed and arranged to reside in a body cavity, a gastrointestinal sleeve configured to expand under a load and contract when the load is removed and a string connecting a bracelet type anchor with the sleeve. Pulling the string transforms the bracelet type anchor from a flexible mode into a rigid state.

The present technology relates to systems, device, and methods for delivering an AIOL into a patients eye. In some embodiments, a tip assembly for delivering an AIOL into a includes an injector tip configured to receive the AIOL. The injector tip can include a distal portion configured to be inserted at least partially into the patients eye. The tip assembly can also include a plunger assembly positionable at least partially within the injector tip. The plunger assembly can include a plunger tip configured to engage the AIOL and an outer member coupled to the plunger tip and positioned at least partially around the plunger tip. When the plunger assembly is actuated, the plunger tip can be configured to move distally relative to the outer member to displace the AIOL out of the injector tip and into the patients eye.

Provided are a medical tubular body delivery device that allows frictional resistance between an outer tube and another member to be reduced and manipulation resistance during pulling of the outer tube to be reduced, thereby making it easy to handle the outer tube, and that allows indwelling of a medical tubular body to be stably performed; and a method for manufacturing the same. A device for delivering a medical tubular body into a body, the device comprising: an outer tube having a lumen in which the medical tubular body is disposed; a traction member connected to the outer tube; a traction member housing tube having a lumen into which the traction member is inserted; a guide wire tube having a lumen into which a guide wire is to be inserted; a covering tube having a lumen in which the traction member housing tube and the guide wire tube are disposed; and a protective tube having a lumen in which the covering tube is disposed, wherein the traction member housing tube and the guide wire tube are fixed to each other on a distal side with respect to a distal end of the covering tube and on a proximal side with respect to a proximal end of the outer tube, and the traction member housing tube and the guide wire tube are not fixed to each other at a portion where the covering tube exists.

IOL injectors and associated methods are described. An IOL injector may include a collapsible portion configured to reduce the length of the IOL injector when the collapsible portion is altered from an uncollapsed configuration to a collapsed configuration. In some instances, an IOL may be advanced from a storage location to a dwell location when the collapsible portion is altered from the uncollapsed configuration to the collapsed configuration. An IOL injector may include one or more of a hydraulic damper and a ribbed damper.

A device for feeding and setting an implant into a blood vessel includes a hollow cylindrical portion formed of an expandable wire mesh netting with a first end and a second end, with a sleeve for receiving the implant in a radially compressed state. The sleeve is arrangeable along a guide wire. The sleeve for receiving the implant in the radially compressed state is formed by an inner sleeve, around which at least one outer sleeve with a distal end and a proximal end is arranged. The implant is arranged in the inner sleeve in such a way that the second end of the hollow cylindrical portion is arranged on the end facing the proximal end of the outer sleeve, so that during setting of the implant, the inner sleeve surrounding the implant can be moved into the outer sleeve in the distal direction so that the implant expands, beginning from the second end.

A frame for a prosthetic heart valve includes a plurality of strut members arranged to form an annular main body and coupled together by a plurality of pivot joints. The main body of the frame is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, and the frame has an inflow end and an outflow end. The frame further includes a plurality of leaflet clamps disposed on the exterior of the main body of the frame and coupled to the strut members. The leaflet clamps are movable between an open position corresponding to the collapsed configuration of the frame and a closed position corresponding to the expanded configuration of the frame. Motion of the main body of the frame between the collapsed configuration and the expanded configuration causes corresponding motion of the leaflet clamps between the open position and the closed position.

The present disclosure provides a pulmonary artery stent. The pulmonary artery stent includes: a metal stent capable of circumferential expansion; and an isolation membrane wrapping the metal stent to isolate the metal stent from an external environment, and the isolation membrane having a circumferential tensile strength less than an axial tensile strength. The embodiments of the present disclosure can not only expand the diameter of the stent according to a change in the diameter of a blood vessel to meet a support performance requirement after the blood vessel enlarges but also isolate the metal portion of the stent from a vascular environment, thus effectively solving a problem of in-stent restenosis.

This document provides implantable intraluminal stent graft medical devices. In some embodiments, the stent graft devices provided herein are implantable in bodily conduits that have side branches, and the stent graft devices are operable to allow the flow of fluids between the conduit and the side branches. In some embodiments, the walls of the stent graft devices provided herein include compliant channels which allow for fluid communication between the interior and the exterior of the stent graft devices. In some embodiments, the compliant channels are configured to inhibit or reduce tissue ingrowth, tissue bridging, and/or endothelialization.

A prosthetic assembly configured for endovascular placement within an aortic arch and method of use thereof. The prosthetic assembly includes a proximal aortic stent-graft prosthesis configured to be positioned within a proximal portion of the aortic arch adjacent to the brachiocephalic artery, a distal aortic stent-graft prosthesis configured to be positioned within a distal portion of the aortic arch adjacent to the left subclavian artery, a first branch stent-graft prosthesis configured to be positioned within the brachiocephalic artery and a second branch stent-graft prosthesis configured to be positioned in one of the left common carotid and the left subclavian artery. When deployed, a proximal end of the first branch stent-graft prosthesis is disposed within a lumen of the proximal aortic stent-graft prosthesis to proximally displace the ostium of the brachiocephalic artery. When deployed, a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses. The overlap is relatively increased by the first branch stent-graft prosthesis proximally displacing the ostium of the brachiocephalic artery.
