A device, system and method for delivery of an implant having an adjustable length. The device is for inserting an implant at an appropriate tissue depth according to a depth finding placeholder, wherein the implant is suitable for insertion to a subject, the device comprising a cannula for receiving the depth finding placeholder and an adjustable depth of insertion element, wherein the adjustable depth of insertion element is adjusted to determine the appropriate tissue depth. The depth finding placeholder may include but is not limited to a wire, such as a K-wire for example. The cannula preferably comprises an opening of sufficient diameter to permit insertion of the depth finding placeholder. The cannula optionally comprises depth indicators, for example by being optionally marked with depth indicator markings. The device preferably comprises a transparent window, or optionally may comprise, additionally or alternatively, an open aperture and/or a viewing screen, to enable the depth indicators to be viewed.

A vacuum extractor for use in childbirth includes a vacuum cup and a handle coupled to the vacuum cup. The handle includes a grip member and a pump member movably mounted on the grip member. The pump member is configured to be manually moved relative to the grip member by a user between a first position and a second position to generate a vacuum within the vacuum cup when the vacuum cup is disposed on the head of a fetus. The grip member includes a first laterally extending member and a second laterally extending member, which are separated from one another in a longitudinal direction. The user can grip either the first laterally extending member or the second laterally extending member while pushing the pump member toward the grip member to move the pump member from the first position to the second position during use of the vacuum extractor.

An ultrasonic surgical tool system with a tip capable of simultaneously vibrating in plural modes. The system includes a console capable of supplying a drive signal to the tip that includes plural components. Each component has a frequency characteristic that is based in part on the equivalent of current through the mechanical components of the tip. The frequency components are different from each other. Based on the application of drive signal the tip undergoes non-linear vibrations.

The present disclosure provides a catheter for treating lesions in a body lumen, such as calcified lesions and occlusions in vasculature. When a voltage is applied across the conductive elements, current flows across an arcing region, from one electrode element to another, to produce shock waves and cavitation bubbles. As a treatment continues, the conductive elements slowly erode at the arcing region where current flows between the electrodes. To increase the lifespan of the electrode assembly, the distal edges of the conductive elements may be shaped to promote erosion of the sheaths in a predetermined or semi-controlled pattern.

An exemplary catheter for use in a body lumen comprises: a catheter body; and a plurality of shock wave emitters disposed at a distal end of the catheter body, each shock wave emitter configured to generate a shock wave that propagates distally of the catheter body, wherein the plurality of shock wave emitters are arrayed about a longitudinal axis of the catheter body such that shock waves emitted from the plurality of shock wave emitters can constructively interfere distally of the catheter body, and wherein each shock wave emitter comprises electrodes separated by a spark gap and at least one electrical connector that connects at least one of the electrodes to an electrode of another shock wave emitter of the plurality of shock wave emitters.

A garment torniquet device includes a pair of pants that has a pair of legs and a pair of channels each integrated into each of a respective one of the pair of legs. A pair of tourniquets is each positioned in the channel in a respective one of the pair of legs of the pair of pants. A respective one of the pair of tourniquets is pullable into a tightened condition to tighten around the femoral artery in the respective user's leg thereby inhibiting the arterial bleeding in the user's respective leg. A pair of clasps is each attached to a respective one of the pair of tourniquets. A respective one of the pair of tourniquets is wrapped around the clasp to for retaining the respective tourniquet in the tightened condition.

In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the iris.

A submucosal injection material whose quality deterioration during a storage period is prevented is provided. It is a submucosal injection material, which contains hyaluronic acid, and to which a dye is added.
