Endoprosthesis assemblies and methods for using the same. In at least one embodiment, the endoprosthesis assembly comprises an endoprosthesis comprising an impermeable inner wall defining an endoprosthesis lumen sized and shaped to permit fluid to flow therethrough, a distal balloon positioned at or near a distal end of the endoprosthesis and capable of inflation to anchor the distal end of the endoprosthesis within a luminal organ, and a proximal balloon positioned at or near a proximal end of the endoprosthesis and capable of inflation to anchor the proximal end of the endoprosthesis within the luminal organ, wherein when the endoprosthesis assembly is positioned within the luminal organ at or near an aneurysm sac, inflation of the distal balloon and the proximal balloon effectively isolates the aneurysm sac and prevents fluid within the aneurysm sac from flowing past the distal balloon and the proximal balloon.

The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure and the other part is an expandable tubular mesh structure, is provided. In the first embodiment, the expandable sponge structure is intended to fill the aneurysm cavity to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure is placed across the aneurysm, contacting the inner wall of healthy vessel proximal and distal to the aneurysm.

In some aspects, a surgical procedure for the removal of a prostate gland is provided. The procedure comprises: (a) positioning an implant material within the urethra, (b) removing the prostate, thereby creating a urethral stump and a bladder neck, wherein the implant material occupies the urethral stump, the bladder neck, or both, and (c) securing the bladder neck to the urethral stump in an anastomosis procedure to establish a path of urine flow from the bladder to an external urethral opening (e.g., the meatus). Subsequently, the implant material is removed from the urethra, for example, by natural urine voiding or by flowing a removal fluid through and/or around the implant material in the urethra. In other aspects, a medical kit is provided.

Applicator for delivering an occluding compound in a fallopian tube includes a lumen extending between a proximal end connectable to a dispenser for containing uncured occluding compound, and a distal end. A spiral wire with a first end is connected to the distal end of the lumen and a free second end. A disconnecting member is configured to disconnect the spiral wire from the distal end. An actuator is configured to actuate the disconnecting member. The distal end of the lumen can be inserted into the fallopian tube. The spiral wire functions as a guide wire. The curable compound embeds the spiral wire. The actuator can be actuated to disconnect the embedded spiral wire from the distal end of the lumen.

Apparatus and methods are disclosed for supporting ischemic tissue of the heart using scaffolds that may be placed within the heart percutaneously. A scaffold assembly may include a layer of biocompatible material detachably secured to a placement rod, such that the placement rod may be used to urge the layer of biocompatible material through a catheter to adjacent an area of ischemic tissue. Anchors may secure the layer of material to the myocardium. Multiple layers of biocompatible material may be placed in the ventricle separately to form the scaffold. In some embodiments, a scaffold is formed or reinforced by injecting a polymer, such as a visco-elastic foam, around an inflatable member inflated within a ventricle.
