An implant having an adhesive structure comprising a planar surface having two sides and rectangular cuboid-based protrusions having pyramidal tips extending from at least one of said sides, optionally having a porous basic supporting structure, and methods of making and using such implants.

Adhesive structure with tissue piercing protrusions on its surface

A polydioxanone film comprising substantially cylindrical polydioxanone pillars on at least one side thereof, said pillars having diameters from about 0.2 &#x3bc;m to about 3 &#x3bc;m, and heights from about 2 &#x3bc;m to about 20 &#x3bc;m from the surface of the film, a process for adsorbing proteins using the film and medical devices incorporating the film.

Super-hydrophilic structures

A laminate and process of making the laminate is disclosed comprising: a surgical mesh having first and second surfaces; and an adhesive structure having adhesive and non-adhesive surfaces, wherein the non-adhesive surface of the adhesive structure is laminated to at least one of said first and second surfaces of said surgical mesh, and the adhesive surface of said adhesive structure has protrusions extending therefrom comprising a resin having a Young's modulus of greater than 17 MPa, which protrusions are of sufficiently low diameter to promote adhesion by increasing physical attractive forces between the adhesive structure and a target surface, as measured by shear adhesion.

Adhesive structure with stiff protrusions on adhesive surface

A blood clotting substrate and device which has a plurality of oxygen plasma-treated polypropylene pillars extending from the surface of a polypropylene film.

Blood clotting substrate and medical device

Synthetic polymer substrates comprising a hierarchical surface structure of multiple domes and multiple pillars on said domes, wherein said substrate is a synthetic polymer film, said domes have diameters in the range from about 5 &#x3bc;m to about 400 &#x3bc;m, heights in the range from about 2.5 &#x3bc;m and about 500 &#x3bc;m, and said pillars have diameters in the range from about 20 nm to about 5 &#x3bc;m and aspect ratios of from about 2 to about 50, and methods of making and using them.

Super-hydrophobic hierarchical structures, method of forming them and medical devices incorporating them

A transducer is provided that comprises a horn having a longitudinal axis, a bonding tool attached to the horn, and an ultrasonic generator attached to the horn and spaced from the bonding tool along the longitudinal axis of the horn. A flexure is attached to the horn between the bonding tool and the ultrasonic generator for supporting the horn whereby to increase its dynamic rigidity in directions transverse to the longitudinal axis.

Transducer and method for mounting the same

A bonding apparatus such as an ultrasonic transducer is provided that comprises an oscillation amplification device having a longitudinal axis and a substantially triangular cross-sectional area on a plane that is orthogonal to the longitudinal axis. An ultrasonic driver is coupled to the oscillation amplification device at a first position along the longitudinal axis and a bonding tool is mounted to the oscillation amplification device at a second position along the longitudinal axis spaced from the first position.
