An intravascular balloon catheter device for treating various size stenosed regions within a blood vessel is provided. A clamp located within a body of a handle assembly is movable between a clamped and unclamped position by way of a button. When clamped, an outer member is secured relative to a sheath to as to expose a portion of a balloon located on a distal end of the outer member. The portion of the balloon remaining within the sheath is restricted from inflation beyond the sheath.

A balloon catheter is disclosed for endovascular procedures. In one embodiment, among others, the balloon catheter includes an elongated catheter body. At a distal end, the catheter body also includes an angled tip and a balloon adjacent to the angled tip. The balloon is inflatable to form an oblong shape.

Flexible high-pressure angioplasty balloons are disclosed herein which utilize an inflatable balloon positioned upon the catheter and a supporting structure secured over or along the catheter at a first location proximal to the balloon and at a second location distal to the balloon. Inflation of the balloon reconfigures the supporting structure to urge the first location and the second location towards one another thereby inhibiting longitudinal elongation of the balloon relative to the catheter. The supporting structure may surround, support, or otherwise extend over the entire length of the balloon and allows for the balloon to retain increased flexibility which enables the balloon to bend or curve even at relatively high inflation pressures.

A clot retrieval device is provided. The clot retrieval device includes a capturing basket having an opening at a proximal end where the capturing basket is deployable downstream from a clot in a blood vessel. The capturing basket is configured to surround a portion of the clot and the opening in the proximal end of the capturing basket is configured to reduce in size such that the capturing basket conforms around the portion of the clot and be retrieved after the capturing basket conforms around the portion of the clot.

A medical apparatus according to one embodiment of the present invention can be used for dissociating adhesion to an epidural space and alleviating stenosis to a spinal canal; and comprises: an insertion part including a first end configured to be inserted into a human body and a second end opposite to the first end, and having a first through hole extended from the first end to the second end and formed inside the insertion part, an expansion part configured to be expandable and formed on an outer surface of the insertion part at a predetermined distance apart from the first end of the insertion part, a pair of wires extending in the insertion part and fixed to a region of the first end of the insertion part, a main body, a dial installed to the main body, and a rotation control part coupled to the dial.

Devices, systems and methods are described for implantation of a prosthesis within a lumen or body cavity and delivery systems for delivering the prosthesis to a location for implantation. A delivery system can include a tether connected to a single directional handle knob for release of the prosthesis within the lumen or body cavity and retraction of the tether towards the handle.

A fiber-reinforced medical balloon includes a cylindrical central portion. The balloon includes first and second conical portions connected to the cylindrical central portion along a central longitudinal axis extending from a first end of the balloon to a second end of the balloon. The balloon includes a plurality of first fiber strands extending from the first end of the balloon to the second end of the balloon. Each strand of the plurality of first fiber strands runs substantially parallel to the longitudinal axis through the cylindrical central portion and radially around at least a portion of the first and second conical portions. The balloon includes at least one second fiber strand extending radially around the central portion. The strands are applied as part of a single continuous fiber.

A balloon sheath and associated methods are provided. An alternative embodiment comprising a sheath having a flaring end and associated methods are also provided.

A multi-lumen catheter, for insertion into and draining a body cavity, that mitigates the risk of obstruction of the drainage ports and drainage lumen of the catheter, reduces the detrimental effects caused by the suction forces of the drainage ports on the body cavity being drained, and reduces the risk of infection of the body cavity being drained by decreasing the residual volume of fluid retained in the body cavity being drained. These advantages are achieved by the novel approach of disposing a perforated filter membrane or a membrane having a relatively large entry port(s) between membrane struts over a segmented retention element and also over the drainage port(s) of the drainage lumen of the catheter thereby creating internal interstitial drainage channels and internal interstitial drainage cavities.

The present embodiments relate generally to devices, systems, and methods for an inflatable device. A system may include an interior inflatable body configured to inflate in response to receiving fluid. The system may include an exterior inflatable body at least partially surrounding the interior inflatable body and configured to inflate when the interior inflatable body inflates and apply an expansion force to the surface to dilate the surface, the exterior inflatable body having a distal portion, a proximal portion, and one or more openings at the distal portion configured to allow the fluid within the interior inflatable body to escape the exterior inflatable body when the interior inflatable body is punctured or bursts.
