Methods and devices for intracorporeal bonding of implants with thermal energy
The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.
URINARY CATHETER OR PLUG AND METHOD FOR MANAGING URINARY INCONTINENCE
The disclosure provides a device and method for managing urinary incontinence. The device includes a platform, a balloon, and a valve. The platform and balloon can include a silicone material, a thermoplastic material, and an adhesive and/or a cement for sealing the urethra. The thermoplastic and silicone materials can soften at the body temperature so that their shape can be adapted to fit the three-dimensional contour of surfaces of the urethra. The balloon seals the internal orifice of the urethra, and the platform can block the leakage associated with the balloon. The valve permits selective urine voiding. The method includes inserting the device into the urethra and the bladder. The method can also include inflating the balloon. The method can further include pulling the balloon so that the balloon is in sealing contact with the neck of the bladder and moving the platform to a suitable position for sealing the urethra.
Flow-diverting covered stent
The described invention provides an endovascular stent device comprising a tubular structure comprising a circumference; wherein a flow-diverting portion of the circumference is covered by a flow-diverting material; a length (l) from a proximal end to a distal end; and an inner diameter (d); wherein the flow-diverting portion of the circumference comprises a length (l′); and the flow-diverting portion of the circumference covers at least 1% to at least 100% of the endovascular stent device. According to some embodiments, the flow-diverting material is adapted to increase blood vessel wall adherence and minimize risk of an endoleak.
EXPANDABLE ANNULUS SEALING RING FOR STENTED MINIMALLY INVASIVE HEART VALVE PROSTHESES
The invention relates to a medical implant, comprising an expandable structure (100) which is designed to be expanded from a crimped state into an expanded state, wherein the structure (100) forms a tubular scaffolding in the expanded state, and wherein the structure (100) comprises a plurality of first struts (101) arranged along a periphery of the structure in said expanded state. According to the invention, the first struts (101) each comprise a recess (O), wherein the medical implant (1) further comprises a sealing member (200) arranged in said recesses (O), wherein said sealing member (200) is formed annularly in said expanded state.
Device and method for establishing an anchorage in tissue
A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.
Personalized prosthesis and methods of use
A personalized prosthesis for implantation at a treatment site of a patient includes a self-expanding mesh or membrane having collapsed and expanded configurations. The collapsed configuration is adapted to be delivered to the treatment site, and the expanded configuration engages the personalized prosthesis with the treatment site. The mesh or membrane is personalized to match the treatment site in the expanded configuration, and has an outer surface that substantially matches the treatment site shape and size. The self-expanding mesh or membrane forms a central lumen configured to allow blood or other body fluids to flow therethrough. Methods of manufacturing and delivery of the personalized prosthesis are also disclosed.
Degradable foldable biological amniotic membrane composite repair stent
The present invention discloses a degradable foldable biological amniotic membrane composite repair stent, comprising a tubular body with an axially extending through hole, the front end of the tubular body is provided with an elastic balloon, and the end of the tubular body is connected to a one-way valve which seals the through hole here, the outer face of the elastic balloon is coated with a foldable reticulated polylactic acid stent, the outer surface of the foldable reticulated polylactic acid stent is coated with a biological amniotic membrane, and there are a plurality of micropores on meshes of the foldable reticulated polylactic acid stent, the plurality of micropores are filled with biological amniotic membrane powder; in the initial state, the elastic balloon, the foldable reticulated polylactic acid stent, and the biological amniotic membrane are compressed into a tight state; in the use state, after being implanted in the body and expanded under pressure, it can conform to the lacrimal duct/uterine cavity to form a tubular or drop-like shape or other spatial shape that adapts to the body cavity.
Injection Molding Method for Degradable Intravascular Stent with Flexible Mold Core Structure
Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing: Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.
