An implant is for the prostatic urethra of a subject, the implant including a first frame being closed-shaped, the first frame includes two longitudinal sections; a second frame being closed-shaped, the second frame includes two longitudinal sections, wherein a mid-portion of one of the longitudinal sections of the first frame is connected in at least one of: directly and indirectly, to a mid-portion of one of the longitudinal sections of the second frame; and a third frame being distinct from the first frame and the second frame, the third frame includes a first arm section joined to the first frame, and a second arm section joined to the second frame, the first arm section and the second arm section extend such to be joined together in an apex portion.

A medical system may comprise: a sheath having a lumen; a medical instrument including a shaft and a clip; and a tether coupling the sheath to the clip. In a first configuration of the medical system, the shaft may extend through the lumen, and the clip may be coupled to the shaft. In a second configuration of the medical system, the clip may be separated from the shaft and the tether may couple the sheath to the clip.

An anastomosis device includes magnets coupled to a wire capable of changing shape from a straight wire into a coil when deployed within a body. The coil exerts compressive force upon layers of tissue caught between loops of the coil. The compressive force is enhanced by attractive forces between magnets coupled with adjacent loops of the coil and causes the coil to cut through the tissue layers, creating an anastomosis. One end of the wire is preferably provided with a connecting member, such as a screw or a nut, for connecting with a delivery device. Positioned on or around the anastomosis device is an expandable drainage mechanism, such as a stent.

Devices and methods for treating a target site in a body lumen are provided. A medical device includes a stent-like structure including a plurality of scoring and non-scoring filaments interwoven with one another. Generally, the stent-like structure will have more non-scoring filaments than scoring filaments to provide greater structural support and to focus the scoring forces on only a few select areas. The stent-like structure is expanded within the target site to score the target site and to provide temporary structural support while the target site is infused with a therapeutic agent. Such therapeutic agent infusion occurs with the use of a drug eluting or drug coated balloon disposed within the stent-like structure or by occluding the target site and introducing a drug into the occluded target site to sit for a period of time.

It is an object of the disclosed technique to provide methods and systems for a prostatic urethra implant for treating prostate enlargement when both the lateral lobes and the median lobe enlarge

A lymphangiogenesis inducing device includes: a rod configured to be inserted into a living tissue; and a wound application unit that is provided on the rod and configured to provide a fine wound to a target site of the living tissue. The wound application unit includes an edge formed on an outer periphery of the rod, and is configured to apply the wound to the target site upon rotation of the rod around a central axis.
