COMPOSITE IMPLANT MATERIAL
A prosthetic implant with improved properties, suitable for implantation to the human body, comprising a composite comprising a base material and a plurality of additives, wherein the additives are selected from radiolucent additives and/or hyperechoic additives; or wherein the additives are selected to reduce the solvent concentration by between 5%-95%; or wherein the additives are selected to increase the elastic modulus by more than 20%; or wherein the additives are selected for combining these effects.
Surgical implant and process of manufacturing thereof
A surgical implant (20) comprises a flexible, areal basic structure (22) having a first face and a second face and being provided with pores (26) extending from the first face to the second face. A barrier layer (24) having a first face and a second face is placed, with its second face, at the first face of the basic structure (2) and attached to the basic structure (22). The barrier layer (24) is deformed into at least part of the pores (26) where it forms, in a respective pore (10), a barrier region (28).
Resorbable nonwoven pouches for medical device implants
Nonwoven resorbable pouches that at least partially enclose implantable medical devices and improved methods for producing the implantable medical device pouches are described. The nonwoven pouches may comprise one or more drugs. Implantable medical devices that are placed in the pouches prior to implantation are prevented from migrating from the site of implantation by tissue ingrowth into the pouch. Antibiotics may be incorporated into the pouches to prevent post-operative infections. The pouches may be formed in fewer steps than conventional pouches, and without polymer coatings. Nonwoven pouches can be formed in one step by dry spinning instead of using multiple processing steps. In embodiments, the nonwoven pouches are smoother on the inside than the outside to tightly fit the implantable medical devices internally while encouraging external tissue ingrowth. In embodiments, the nonwoven pouches eliminate the use of knitted or woven multifilament fibers that can trap bacteria and result in post-operative infection.
A MEDICAL SUPPORT DEVICE
A medical support device (1), for use in a woman's breast as an implant without incapsulated material, wherein the medical support device (1) comprises at least a wall shaped portion (2) having a first side (3), which shows a bulge out of a plane (4), and a second side (5) of the wall shaped portion (2) has a corresponding cavity, for example a dome shape, wherein the medical support device (1) comprises an elastomer. The device will keep endogenous tissue and/or fat and/or added material, such as hyaluronic acid, in place inside of deep gland tissue of a woman's breast by means of being attached to tissue, such as muscle. A method of producing and to use such a medical support device (1).
ENDOPROSTHESIS AND METHOD OF MANUFACTURING AN ENDOPROSTHESIS
The invention relates to an endoprosthesis (60), in particular a vascular stent or a heart stent. The endoprosthesis comprises a stent structure (2) with a stent surface (3) and has at least one fiber (1) arranged on the stent surface (3). The stent structure (2), preferably the stent surface (3), comprises an attachment mechanism (4,5,6,7) to directly attach a fiber (1) on the stent.
RESORBABLE NONWOVEN POUCHES FOR MEDICAL DEVICE IMPLANTS
Nonwoven resorbable pouches that at least partially enclose implantable medical devices and improved methods for producing the implantable medical device pouches are described. The nonwoven pouches may comprise one or more drugs. Implantable medical devices that are placed in the pouches prior to implantation are prevented from migrating from the site of implantation by tissue ingrowth into the pouch. Antibiotics may be incorporated into the pouches to prevent post-operative infections. The pouches may be formed in fewer steps than conventional pouches, and without polymer coatings. Nonwoven pouches can be formed in one step by dry spinning instead of using multiple processing steps. In embodiments, the nonwoven pouches are smoother on the inside than the outside to tightly fit the implantable medical devices internally while encouraging external tissue ingrowth. In embodiments, the nonwoven pouches eliminate the use of knitted or woven multifilament fibers that can trap bacteria and result in post-operative infection.
TISSUE GRAFTS WITH PRE-MADE ATTACHMENT POINTS
The present disclosure pertains to membranous tissue grafts comprising one or more pre-made attachment points. The one or more pre-made attachment points may include pre-made markings and/or pre-made suture holes. The membranous tissue grafts can be in the form of a tube. The membranous tissue grafts can also be rectangular in shape and can be used in a nerve repair by wrapping the severed or damaged nerve. In some embodiments, the membranous tissue grafts are suitable for repairing severed nerves that have a short gap or no gap with a gap of less than 5 mm between the severed stumps. Accordingly, methods are provided for repairing a damaged or severed nerve by implanting the membranous tissue grafts on to the damaged or severed nerve.
TISSUE EXPANSION DEVICE
A tissue expansion device can be implanted temporarily beneath skin of a patient and removed upon expansion of overlying tissue. The device can include an expandable shell having a smooth or glossy outer surface and an injection port. The expandable shell can form an expandable chamber and have an anterior portion and a posterior portion. The injection port can be coupled to the anterior portion of the shell and be in fluid communication with the chamber and configured to permit injection of fluid into the chamber from a hypodermic needle. The device can have a plurality of tabs coupled to the posterior portion of the shell having one or more colors or attributes. The device can also include an orientation indicator visible along the anterior portion of the shell for assisting a clinician and orienting the device during the implantation procedure.
IMPLANT WITH ELASTOMERIC MEMBRANE AND METHODS OF FABRICATION THEREOF
A method of forming an implant includes providing a preformed shell formed from at least one cured elastomeric layer. The shell includes an outer surface, an inner surface, and an opening for accessing an interior volume of the shell. The method further includes expanding the shell to an expanded state, in which the interior volume is greater than the interior volume of the shell at a time of forming the shell and forming an inner zone having at least one inner elastomeric layer on at least a portion of the inner surface of the shell, while the shell is in the expanded state, thereby forming a multi-zone shell. The method further includes reducing the interior volume of the multi-zone shell, thereby contracting the at least one inner elastomeric layer of the inner zone and causing texturing of the at least one inner elastomeric layer.
Implantable heart valve devices, mitral valve repair devices and associated systems and methods
Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet.
