A universal mechanical dilator combined with massaging action comprises a probe (12) consisting of a two rods (22 and 24), a drive unit (14) and an adapter (16) that connects the probe (12) to the drive unit. The instrument is intended for dilation of the urethra or other ducts of a human body and can operate in three different modes: pure dilation, pure vibration, and dilations combined with vibrations. This is achieved by using the adapter (16) as an adjustable coupling. The probe (12) together with the adapter (16) can be disconnected from the drive unit (14) and used separately as a mechanical manual dilator. At its distal end, the probe (12) has means for connecting replaceable tips (28a, 32a) used for various applications, i.e., urethral, anal, vaginal, etc. The invention also relates to a method of treatment of voiding or an orectal diseases by combining dilations with vibrations. The instrument can also be used for training sphincteric muscles.

A transdermal drug delivery system for the topical application of one or more active agents contained in one or more polymeric and / or adhesive carrier layers, proximate to a non-drug containing polymeric backing layer which can control the delivery rate and profile of the transdermal drug delivery system by adjusting the moisture vapor transmission rate of the polymeric backing layer.

A medical implant (20) includes first and second ring members (22,24), each including a resilient framework (26) having a generally cylindrical form. A tubular sleeve (28) is fixed to the first and second ring members so as to hold the ring members in mutual longitudinal alignment, thereby defining a lumen (32) passing through the ring members. A constricting element (30) is fit around the sleeve at a location intermediate the first and second ring members so as to reduce a diameter of the lumen at the location.

An attachment structure for a load-bearing fabric including an expandable carrier secured to an un-stretched load-bearing fabric. To attach the carrier to a support frame, the carrier and fabric are stretched together to desired shape and secured to the frame. An indexing system registers the carrier and frame and optionally stretches the fabric a predetermined amount. The carrier and frame can include a lip that flexes in one direction and maintains the fabric in a stretched condition in another. A tool that joins the carrier and frame generally includes a drive roller and a primary roller adapted to move toward one another and join a carrier and the support frame disposed therebetween. The tool may include alignment rollers near the primary and drive rollers to track along and align the carrier and frame.

A safety needle device includes a housing including a passageway with a needle cannula extending therefrom. A shielding member is movable between a first position in which a puncture tip of the needle cannula is exposed therefrom and a second position in which the puncture tip of the needle cannula is encompassed therein. The shielding member is maintained in the first position against a biasing force which biases the shielding member toward the second position. A fluid and / or temperature activation material, such as a hydrogel or a compressed sponge, is associated with the shielding member and is adapted to deform upon contact with a fluid medium and / or a certain temperature or temperature range. Fluid flowing through the needle cannula, such as blood flow during a blood collection procedure, causes the activation material to deform, such as through expansion, thereby releasing the shielding member from the first position and allowing the drive member to bias the shielding member toward the second position.

A medical cauterization snare includes a tubular member such as a catheter, a rod or wire disposed at least partially inside the tubular member, and a resilient loop of a first size attached to a distal end of the rod or wire. The loop includes a nose on a side of the loop opposite the wire. The loop further includes two loop sections each extending between the wire and the nose. The loop sections are each formed with a respective notch or dent for enabling a use of the loop in a second size smaller than the first size. Positioning the loop relative to the tubular member so that the notches or dents are disposed at a mouth opening of the tubular member generates this secondary deployment configuration.

The present invention relates to RJ45 modular inserts that are connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to reduce near-end cross-talk (“NEXT”) without compromising impedance. NEXT is substantially reduced by utilizing a low reactance dielectric insert with a two-stage combination positive and negative compensation removal technique. By utilizing this method, the pair-to-pair NEXT is substantially reduced and differential pair impedance are controlled in a simple and cost effective manner.

The second side wall section (1b) extends a distance past the transverse peelable connection (18) to form a gripping member (21).

A planar wound dressing for the heel of the foot, having an adhesive layer with a backing layer, and three slits which can be reversibly closed and joined to form a non-planar wound dressing that conforms to and adheres to the heel of the foot. The wound dressing is constructed so that one slit is placed over the Achilles tendon, the second slit is placed over the inner ankle, and the third slit is placed over the outer ankle. With this orientation after closure of the slits the wound dressing covers the heel uniformly without wrinkles, gaps, leakage, contamination, or infection. The wound dressing is particularly useful in protecting and preventing blisters on the heel that occur in sports such as soccer, track, and the like.

A patch panel assembly having a bracket with a base extending between first and second side walls. The bracket defines a cable receiving passageway. First and second patch panels are coupled to the first and second side walls for pivotal movement about first and second vertical pivot axes between open and closed positions. The patch panels are selectively engageable with one another in their closed positions for limiting access across the cable receiving passageway.
