Abstract: Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile, thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.

Abstract: An implantable soft tissue prosthesis device comprising a silicone elastomer-shell filled with silicone gel or liquid, which among the layers that constitute its shell includes a barrier layer formed of a low permeability silicone, which impedes the bleeding or diffusion of the silicone gel from the inside of the implant to its surroundings through the shell. This barrier layer is given a coloration different to the other layers of the shell, making it visible in the finished product. The coloration of the barrier layer gives the fabricator of the implant as well as to medical personnel, the possibility to identify the presence of the barrier layer and its homogeneity, improving the safety of the device.

The scaffold is configured to permit the infiltration of human tissue into the plurality of voids. The reinforcement member extends through at least a portion of the scaffold and is configured to resist compressive forces exerted on the scaffold. Also described are embodiments where the void occlusion device is biocompatible, bioresorbable, elastic, and suitable for radio imaging.
Abstract: A surgical instrument (100) for placement of a movement restriction device (10) for use in a surgical procedure for treating reflux disease in a patient. The instrument comprises a sleeve (113) and a holding device (111) configured to engage the movement restriction device, wherein the holding device is configured to be placed within the sleeve and be displaceable in relation to the sleeve. The instrument further comprises a first handling portion (101) connected to the sleeve, and a second handling portion (102) connected to the holding device. The handling of at least one of the first and second handling portion creates relative displacement of the holding device in relation to the sleeve, which disengages the holding device from the movement restriction device for performing the placement of the movement restriction device.
