A small diameter vascular prosthesis includes an outer textile graft, an intermediate self-supporting coil or stent and an inner microporous layer. The outer textile graft allows for tissue ingrowth. The inner microporous layer provides blood impermeability without preclotting the prosthesis. The coil or stent provides kink resistance and resistance again collapsing of the outer textile graft and the inner microporous layer.

METHOD FOR FUSING A HUMAN OR ANIMAL JOINT AS WELL AS FUSION DEVICE AND TOOL SET FOR CARRYING OUT THE METHOD

The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

PERSONALIZED PROSTHESIS AND METHODS OF USE
20180008437 · 2018-01-11 · ·

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.

Non-gravitational fluid delivery device for ophthalmic applications

A fluid dispensing device includes a cartridge comprising a housing and a head coupled to the housing. The housing forms a first chamber configured to accommodate a fluid; and the head includes a nozzle; and an elastomeric wall that is spaced from the nozzle to form a holding chamber. The holding chamber is in fluid communication with the first chamber and configured to accommodate a portion of the fluid; and the nozzle forms one or more openings to eject the portion of the fluid from the holding chamber. The one or more openings form an oblong shape such that a length of the oblong shape is greater than a width of the oblong shape. The one or more openings can include two parallel slots that together form the oblong shape.

A stent includes a main body having a plurality of rings that form a helix. Each of the plurality of rings includes a plurality of skewed v-shaped elements that each have a first leg and a second leg that is longer than the first leg. The stent further includes a first end ring and a second end ring positioned to an opposite side of the main body from the first end ring. Each of the plurality of rings of the main body is angled with respect to the first end ring and the second end ring. The stent further includes a first transitional region for connecting the first end ring to the main body, and a second transitional region for connecting the second end ring to the main body.

A handheld implantation device for implantation of a retinal tissue implant at an implantation site. The handheld implantation device includes a handheld implantation tool having a leading implantation tool end and a trailing implantation tool end, an implant holder for peripherally holding a retinal tissue implant including an uppermost viable retinal tissue and a lowermost basement membrane and a clinician-operated attachment arrangement for initial attaching the implant holder at the leading implantation tool end and subsequent selected detaching the implant holder therefrom at the implantation site for implantation of the implant holder together with the retinal tissue implant thereat.

URINARY CATHETER OR PLUG AND METHOD FOR MANAGING URINARY INCONTINENCE
20230036376 · 2023-02-02 ·

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.

Post deployment radial force recovery of biodegradable scaffolds
11628077 · 2023-04-18 · ·

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.
