A tissue press and method for shaping or compressing a piece of tissue comprises first and second members movable relative to each other. A first forming element of a predetermined shape is selectively engageable on the first member. A second forming element of predetermined shape is selectively engageable on the second member. The first and second forming elements are positionable on opposite sides of the piece of tissue. The first and second members are relatively movable between a first spaced apart condition and a second condition in which the piece of tissue is held between the first and second forming elements. Means are preferably provided for monitoring and controlling the amount of pressure applied to the piece of tissue, in order to maintain the tissue in a viable living condition. Means may also be provided for draining off fluid from compressed tissue, so that the tissue can be implanted in a compressed state and imbibe fluid from the host site. A retainer, which may be expandable, can be used to maintain the tissue graft in a compressed condition.

An implant is formed of an expandable material. An opening is formed in a bone in a patient's body. At least a portion of the implant is positioned in the opening in the bone in the patient's body. The implant is retained against movement relative to the bone in the patient's body by absorbing body fluid with the implant and expanding the implant while the implant is disposed in the opening in the bone in the patient's body. The implant may be a hip replacement member.

Multi-functional urine collection devices, embodiments of which can include a self-expanding container having a receptacle for receiving urine from the tubing, a pump for moving urine through the tubing and into a receptacle, extendable tubing that may be shortened and / or lengthened, and / or one or more meters for monitoring, measuring, transmitting or storing a characteristic from the urine.

Hydrophobic coating compositions are provided as are processes to coat articles with the compositions. Extremely hydrophobic coatings are provided by the compositions. Durable, weatherable and scratch-resistant coatings are provided by compositions comprising a fluorinated component and an adhesion promoter compound. The adhesion promoter compound can include an alkoxy group, a furfuryl-containing ring structure, and a reactive group.

A foldable intraocular lens (IOL) includes an optic and at least one fixation member for supporting the optic in the anterior chamber of an eye. The fixation member includes an intermediate portion that extends a first direction away from the optic, and a leg portion that intersects with an outer end of the intermediate portion and extends a second direction, different from the first direction, away from the outer end. The leg portion preferably includes a reduced width region near the intersection with the intermediate portion. The reduced width region acts essentially as a hinge allowing the leg portion to flex about the intermediate portion in responsive to compressive forces, while the intermediate portion and optic remain stable.

An orthopedic impacting tool comprises a motor, an energy storage arrangement, a striker, and an anvil. The motor stores energy in the energy arrangement means and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.

The invention relates to the technical field of spunlace non-woven, and discloses a combined spunlace non-woven fabric for a personal hygiene nursing product water absorption surface layer and a preparation method of the non-woven fabric. The spunlace non-woven fabric comprises a first fiber layer and a second fiber layer, the first fiber layer comprises hydrophilic fibers, the second fiber layercomprises hydrophobic fibers, the fibers in the first fiber layer and the second fiber layer are entangled each other, a plurality of projections and a plurality of through holes are distributed on the surface of the first fiber layer, and the through holes penetrate the second fiber layer. The non-woven fabric comprises double-layer fibers with different solution absorption performances, one surface contacting with human skins has hydrophilicity, softness and skin-friendly performance of the fabric cannot be affected, the other surface without contacting with the human skins has hydrophobicity, so that ratio of hydrophilic fibers can be reduced, liquid storage amount of the surface layer is reduced, liquid absorbed by the first fiber layer can rapidly pass the second fiber layer to entera flow guide layer, and dry and comfortable performances of surface layer materials are improved.

The present invention provides a safe, low-cost, effective composition and method for the remediation of contaminated subsurface material, the composition comprising solid alkaline material preferably in combination with stabilizing agents, that can be used to increase or maintain the pH of a subsurface zone and improve the performance of in situ treatment processes.
