A stent insertion device for connecting human digestive organs includes a first handle being connected to one side of an outer tube, the first handle including a first inner passage communicating with the outer tube, a second handle being connected to a first side of an inner tube, the second handle including a second inner passage communicating with the inner tube, wherein a mounting space is provided between the outer tube and the inner tube at a second side of the inner tube, a stent for connecting human digestive organs being compressed and mounted to the mounting space, a third handle being connected to a first side of an insulation tube, the third handle including a third inner passage communicating with the insulation tube, and a needle knife being connected to a second side of the insulation tube.

A cartridge device is provided for applying a fiber matrix to a tubular member such as a saphenous vein graft. The cartridge includes a housing, a tubular member holder, a rotational drive, and a polymer delivery assembly. The housing defines a chamber which surrounds the tubular member holder. The rotational drive rotates the tubular member during the fiber application process.

Extra-urethral implants and methods of use are disclosed. Implants can treat disorders or diseases of the prostate by, for example, enlarging the lumen of the prostatic urethra.

A device for maintaining patency of a prostatic urethra includes a stent having a proximal end, a distal end, and a passageway therebetween. The device includes longitudinal and angled struts and nodes, each longitudinal strut coupled to at least one angled strut at a corresponding node, the struts and nodes coupled to each other to form a plurality of cells, circumferentially adjacent cells forming stent regions. The stent includes a nose region, a body region, and a tail region. The stent is configured to expand from a compressed configuration to an expanded configuration within a bodily lumen. The stent includes a collapsibility gradient along its length such that it provides a nose region radial force at the nose region, a body region radial force at the body region, and a tail region radial force at the tail region, wherein the nose region radial force is less than the tail region radial force, and the tail region radial force is less than the body region radial force.

Extra-urethral implants and methods of use are disclosed. Implants can treat disorders or diseases of the prostate by, for example, enlarging the lumen of the prostatic urethra.

A device for implantation into a prostate-cavity of a patient having undergone a prostatectomy procedure is disclosed herein. The device includes a bag-body having an outer-shell and an inner-volume. In a preferred embodiment, the inner-volume is filled with a saline material. The device effectively fills the void after a prostatectomy procedure, helping patients quickly recover from the current side effects of surgery and preventing incontinence without having to endure intense therapy or invasive surgery.

An apparatus is configured to be implanted within a biological structure. The apparatus includes a plurality of magnetic elements, an absorbable component, and a non-absorbable component. The plurality of magnetic elements are configured to transition the biological structure between an occluded state and an opened state. The plurality of magnetic elements are biased to encourage the biological structure toward the occluded state. The absorbable component includes a therapeutic substance. The absorbable component is configured to temporarily couple the plurality of magnetic elements with the biological structure when the apparatus is initially implanted within the biological structure.

The present invention's goal is to devise an apparatus (here-forth called punch-ball) made of a tension-reversible membrane that will assume a particular three-dimensional predetermined shape when under tension, apparatus that will border a central empty space, central space limited by the interior face of the membrane, and central space that will be in direct communication with the exterior space outside of the external face of the punch-ball through orifices in the membrane (here-forth called punches), punches that will not decrease the ability of the membrane to exhibit a tension force. The punch-ball can be used freestanding or in connection with an object representing a confined space that will be abutting the exterior face of the punch-ball when the punch-ball is under tension. The punches will allow fluid to flow freely or solids to be transferred freely between the interior and exterior of the punch-ball membrane without any limitations to the initial flow through the cavity prior to the punch-ball membrane being deployed in the cavity, the interior face of the membrane being defined as surrounding the empty space inside the punch-ball while the exterior face of the membrane as facing the exterior of the punch-ball. The membrane will be provided with hinge borders (borders that will lack completely or partially the property of being under tension, and at same time have various degrees of elasticity or deformability), borders that will allow the punch ball shape to adapt to the shape of the cavity in which it will be deployed, or for the action to be undertaken. At the end of the action performed the tension in the membrane will cease, the punch-ball will be un-deployed and then removed from the location of action.

There are provided a connectable catheter system, device and methods of use thereof. The connectable catheter system, comprising: an intermediary catheter and a reconnectable indwelling stent wherein the intermediary catheter and the indwelling stent are configured to connect, within a subject body to form a continuous fluid conduit between the intermediary catheter and the reconnectable indwelling stent and to further allow controlled release of substances and/or heating of internal target regions.

An alloy material and an implantable medical device using the alloy material are disclosed. The material contains the following elements in the weight percentages given: magnesium: less than 3%; selenium: 0.001%-0.5%; strontium: 0.001%-0.5%; zinc: the remainder.
