摘要:
A clean release split carton (102) for a medical device (106) includes a first carton tube (112) coupled to a second carton tube (114) by a closure label (126). To open the clean release split carton, a tear string (128) is pulled to tear the closure label thus separating the first carton tube from the second carton tube. The individual carton tubes are then removed from the medical device. The clean release split carton avoids the generation of particulates while opening the carton and make removing the medical device easier.

The present subject matter describes a suturing ring (300) for a prosthetic heart valve. The suturing ring (300, 800) has a variable annular thickness reducing continuously from a mid-circumferential plane of the suturing ring (300, 800) towards a top peripheral edge (306, 806) and a bottom peripheral edge (308, 808) of the suturing ring (300, 800).

A heart valve assembly has a frame having an anchoring section defined by a plurality of rows of cells, with each cell defined by a plurality of struts that encircle each cell, and a pair of legs extending from the anchoring section. The assembly also includes a leaflet assembly that has a plurality of leaflets that are stitched to the legs. The heart valve assembly is delivered to the location of a native mitral annulus, and the anchoring section is deployed inside the left atrium such that the anchoring section is completely retained in the left atrium, and the legs and leaflets extend through the native mitral annulus.

An implantable permanent filter assembly (1) for deployment in a bifurcated vessel comprises a main vessel and at least two branches. This assembly comprises a filtering sleeve (2) formed of an expendable braided framework (20) able to expand from a radially compressed state in a delivery configuration to a radially expanded state. The filtering sleeve extends along an axis and defines a cylindrical lumen devoid of impermeable layer, having a distal end configured to extend toward the branches of the bifurcated vessel and a proximal end configured to extend toward away from the branches of the bifurcated vessel. The braided framework has a plurality of layers (22,23,24) of wires (25) made of biocompatible material, each layer forming a mesh, the meshes forming a lattice with a plurality of wires of each layers. The lattice, when observed normal with respect to a wall of the implantable endoluminal prosthesis, defines polygonal openings, the diameter of the wire being at least 20 micrometres and at most 100 micrometres.

A heart valve assembly has a leaflet support structure and a leaflet assembly. The leaflet support structure has a wire frame that supports the leaflet assembly. The leaflet assembly has first and second separate leaflets, each of which is comprised of a skirt section and a sinus leaflet section. Each skirt section has a flange portion and a body portion that has a smaller diameter than the flange portion, with the body portion having opposing side edges, and a curved opening defined by a first stitching edge at about the central portion of the body portion. Each sinus leaflet section has an outflow edge, and a curved second stitching edge, with the sinus leaflet section stitched to the skirt section along the first and second stitching edges. The opposing side edges of the body portion of the first leaflet are stitched to the corresponding side edges of the body portion of the second leaflet.

Elevated levels of spermidine/spermine N 1 -acetyltransferase (SSAT) gene expression expression were observed in breast, prostate and lung cancer cell lines. Elevated levels of SSAT gene expression were verified in tissues from patients with breast, prostate and lung cancer. Elevated SSAT gene expression is elevated in different human cancers and elevated SSAT gene expression may accordingly serve as a companion diagnostic biomarker for detection and monitoring of cancer progression.
摘要:
The present invention generally relates to local therapies for the eye and, more particularly, to shaped controlled-release ocular implant devices, including methods for making and using such devices, for delivery of therapeutic agents to the eye. A molded two-layer ocular implant comprises a therapeutic agent for treatment or prevention of a disorder of the eye. The implant comprises a polymer layer and a silicone adhesive layer with a therapeutic agent interspersed therein and joined to the polymer layer. This implant is for placement in the sub-Tenons space of the eye and provides sustained release of the therapeutic agent during the treatment or prevention of the disorder of the eye.
摘要:
Methods and devices for altering the power of a lens, such as an intraocular lens, are disclosed. In one method, the lens comprises a single polymer matrix containing crosslinkable pendant groups, wherein the polymer matrix increases in volume when crosslinked. The lens does not contain free monomer. Upon exposure to ultraviolet radiation, crosslinking causes the exposed portion of the lens to increase in volume, causing an increase in the refractive index. In another method, the lens comprises a polymer matrix containing photobleachable chromophores. Upon exposure to ultraviolet radiation, photobleaching causes a decrease in refractive index in the exposed portion without any change in lens thickness. These methods avoid the need to wait for diffusion to occur to change the lens shape and avoid the need for a second exposure to radiation to lock in the changes to the lens.
