A detachable tip sheathed balloon microcatheter is provided for delivering an embolic agent to a target location for the embolization of an arteriovenous malformation (AVM). The detachable tip sheathed balloon microcatheter including a balloon microcatheter including a first shaft and an inflatable balloon that is coupled to a distal end portion of the first shaft; and a detachable tip assembly that is configured to be detachably coupled to the first shaft of the balloon microcatheter. The detachable tip assembly includes a protective balloon sheath that is coupled to a proximal end portion of the second shaft, wherein when the detachable tip assembly is coupled to the balloon microcatheter, the protective balloon sheath surrounds at least a portion of the inflatable balloon.

Provided is a balloon catheter wherein a balloon is less likely to swell in the protective tube during an air leak test of the balloon in a state where the balloon having projecting portions is housed in a lumen of the protective tube. A balloon catheter contains: a shaft extending in a distal-proximal direction; a balloon having wing-shaped portions; projecting portions disposed on an outer surface of the balloon; and a protective tube in which the balloon is disposed, wherein, in a cross section perpendicular to the distal-proximal direction at a midpoint of a length in the distal-proximal direction of the protective tube, a distance from a centroid of the protective tube through an apex of each projecting portion to an inner surface of the protective tube is longer than a distance from the centroid through none of the projecting portions to the inner surface of the protective tube.

An apparatus and method for inactivating infectious organisms in human body are provided. The apparatus comprises a body having an elongated balloon shape with an open end; a disinfectant containing chlorine dioxide accepted in the body; and an activation module coupled to the body, the activation module includes a case having an opening capable of accommodating the body, an energy supply unit for supplying energy to the disinfectant to activate the chlorine dioxide and a controller for controlling the energy supply unit. The method comprises the steps of inserting the device into a vagina and controlling a degree of activation of the chlorine dioxide so as to inactive infectious organisms in the vagina by adjusting an intensity of the energy.

Devices and methods for delivering substances to lung tissue through an extra-anatomic passage created in an airway.

Systems and methods for selective auto-retroperfusion along with regional mild hypothermia. In at least one embodiment of a system for providing a retroperfusion therapy to a venous vessel of the present disclosure, the system comprises a catheter for controlling blood perfusion pressure, the catheter comprising a body having a proximal open end, a distal end, a lumen extending between the proximal open end and the distal end, and a plurality of orifices disposed thereon, each of the orifices in fluid communication with the lumen, and at least one expandable balloon, each of the at least one expandable balloons coupled with the body, having an interior that is in fluid communication with the lumen, and adapted to move between an expanded configuration and a deflated configuration, and a flow unit for regulating the flow and pressure of a bodily fluid, and a regional hypothermia system operably coupled to the catheter, the regional hypothermia system operable to reduce and/or regulate a temperature of the bodily fluid flowing therethrough.

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

An improved medical device reduces the loss of longitudinal length during expansion of a stent-graft from a compressed state to an expanded state. For example, the stent-graft is placed over a cover that provides resistance to expansion of the balloon during inflation, which reduces longitudinal compressing forces exerted on the stent-graft.

A cage can be positioned around a medical balloon, such as an angioplasty balloon, to assist in a medical procedure. The cage can include a plurality of strips, each extending between a set of rings including first and second rings. As the balloon expands, the first and second rings move closer together and allow the strips to expand outward. The cage may have wedge dissectors on the strips.

Provided is a balloon catheter wherein a balloon is less likely to swell in the protective tube during an air leak test of the balloon in a state where the balloon having projecting portions is housed in a lumen of the protective tube. A balloon catheter comprising: a shaft extending in a distal-proximal direction; a balloon disposed on a distal side of the shaft and having, in a contracted state, a plurality of wing-shaped portions; projecting portions each disposed on a portion, of an outer surface of the balloon, that is none of the wing-shaped portions; and a protective tube having a lumen in which the balloon is disposed, wherein none of the wing-shaped portions is present between an apex of each projecting portion and a point, on an inner surface of the protective tube, that is at a shortest distance from the apex of the projecting portion.

Methods and apparatus are provided to facilitate the minimally invasive removal of tissue biopsies and to facilitate the direct approach to anesthetizing the chest wall, in accordance with embodiments of the present invention. A pull-type cutting device 1 comprises two coaxially nested tubes, each extending from a proximal end 21 to a distal end 22. The first tube 61 defines a guide wire lumen 23 for slidingly receiving a guide wire. The second tube 63 extends over the first tube 60 and coupled thereto at the distal end 22 defining an expandable portion 13 adjacent the distal end 22. The second tube 63 defines an inflation lumen 25 extending from the shaft proximal end 21 to the expandable portion 13. The inflation lumen 25 communicates inflation fluid from the proximal end 21 to the expandable portion 13 so as to inflate and deploy the expandable portion 13. Disposed adjacent the shaft distal end 22 is a cutting head 10 comprising the expandable portion 13 having a cutting portion 11 distal from the shaft distal end 22.
