Methods of manufacturing an embolic filter balloon
An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.
Method for forming a base knit suitable for manufacturing hernia prostheses and hernia prostheses obtained therefrom
The invention relates to a method for forming a prosthetic base knit (1) made of two parallel sheets of porous knits, namely a first sheet (2) of porous knit and a second sheet of porous knit, said two parallel sheets being joined together in a discrete manner by a plurality of connecting porous knits (4) spaced apart from each other. The invention further relates to a method for manufacturing H-shaped prostheses for hernia repair from said base knit thus obtained and to the prostheses obtained therefrom.
Post deployment radial force recovery of biodegradable scaffolds
Post deployment radial force recovery of biodegradable scaffolds are described where a high molecular weight polymer may be formed into a high molecular weight scaffold by solution casting into a tubular substrate such that the scaffold retains its mechanical properties through processing. The tubular substrate is laser cut and subsequently crimped onto a catheter for deployment into a body lumen. The polymeric scaffold may retain its mechanical properties and result in increased radial strength post-deployment in a saline environment, e.g., within a body lumen. This scaffold enhancement may be attributable at least in part to entanglement of high molecular weight polymer chains as one factor that effects radial force recovery and also to the design or geometry of the scaffold as another factor that effects radial force recovery after deployment.
Method for protecting skeletonized blood vessels
Skeletonized blood vessels for use as vascular grafts are protected from biomechanical injury and/or certain cellular and extracellular changes by application of a biocompatible hydrogel to the vessel exterior. The hydrogel may be applied to the vessel graft before or after harvesting from a donor patient.
Porous structures produced by additive layer manufacturing
A three-dimensional structure is formed when layers of a material are deposited onto a substrate and scanned with a high energy beam to at least partially melt each layer of the material. Upon scanning the layers at predetermined locations a tube device having a first tube and a second tube intersected with the first tube is formed.
System and method for preparing a soft tissue graft
A system and method for loading a suture construct on a soft tissue graft with a graft assembly. The graft assembly includes a frame with an opening extending between a proximal end and a distal end. The frame has a wall with a first side extending to a first edge and a second side extending to a second edge. A lumen extends between the first side and the second side and a plurality of channels extend through the wall between the first edge and the second edge. The graft assembly also includes a transverse hole extending through the proximal end of the frame and a pin removably inserted into the transverse hole.
Laser-produced porous structure
The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.
Systems and methods for tissue dissection in corneal transplants
A dissection system for corneal transplants includes a housing including a contact side to be positioned against a cornea. The housing includes an interior passageway with an opening at the contact side. The dissection system includes a blade assembly disposed in the interior passageway. The blade assembly includes a first blade and a second blade. The first blade includes a first cutting edge and the second blade includes a second cutting edge. The first blade and the second blade are movable relative to the housing such that the first cutting edge and the second cutting edge extend through the opening of the housing and out of the interior passageway. The first cutting edge produces a first cut in the cornea. The second cutting edge produces a second cut in the cornea. The first cut and the second cut define a volume of tissue for removal from the cornea.
Stent graft systems with restraints in channels and methods thereof
A stent graft system includes a first layer of graft material, a second layer of graft material, one or more stent members, one or more reducing belts, and a release wire. The one or more stent members are located between the first layer of graft material and the second layer of graft material. The second layer of graft material is formed to have a corresponding channel over each of the one or more stent members. The one or more reducing belts each include a loop at both ends and each is located in a corresponding channel around a corresponding one of the stent members. The release wire passes through both loops of each of the one or more reducing belts when the one or more stent members are in a compressed state. Pulling the release wire allows for the stent graft system to radially expand.
TISSUE GRAFT FIXTURE
A fixture includes a first ring member and a second ring member. The first ring member has a first open center and has a first tool connector disposed at a first radial position relative to the first open center. The second ring member has a second open center coupled to the first ring member at a joint. The joint is disposed at a second radial position relative to the first open center. The joint has a second tool connector. The joint is configured to enable movement of the first ring member relative to the second ring member.
