According to aspects described herein, there is disclosed an improved hot balloon catheter delivery system for shape memory tubular stents. An outer sheath is provided on the delivery system that facilitates stent placement on a balloon during delivery through an endoscope. In one embodiment, the stent may be positioned between radiopaque markers/electrodes and the balloon may be heated. The stent may be prevented from moving proximally relative to the catheter as the delivery system is tracked through the patient's anatomical passageways. The outer sheath may be positioned to ride over the proximal cone of the hot balloon catheter and abut the proximal end of the stent to facilitate proper alignment of the balloon for deployment. Upon deployment of the stent in an appropriate position, the sheath may be pulled away from the stent to expose the proximal cone of the balloon and thereby allow balloon and stent expansion.

Devices and methods are provided for performing an ablation procedure on tissue with flow monitoring using flow sensors. The devices include a catheter, and at least one flow sensor disposed on the catheter, and a component for applying the ablation procedure. An assessment module provides an indication of the efficacy of the ablation procedure based on the flow measurement from the flow sensor.

A medical device for fragmenting objects and aspirating remaining debris enables a physician or other medical personnel quickly and easily remove objects, such as kidney stones, from a patient. The medical device can include a dual-lumen elongated member and a handle coupled to the elongated member. A first one of the lumens provides a suction passageway, and a second one of the lumens receives a laser fiber for delivering laser energy to an object, such as a kidney stone, within the patient. The handle can include a positioning mechanism to enable the physician by manual manipulation to move and hold in place the laser fiber longitudinally within the second lumen.

A high performance coil over-core guide wire. The guide wire incorporates a nickel-titanium core with a stainless steel coil to provide a wire with improved kink resistance and good pushability.

An apparatus and method for access to the inside of a body includes a transparent sheath with a radiopaque marking and fastener for securing a guidewire or catheter. The transparent sheath permits objects located within and near the sheath to be visualized with an external imaging system. Objects located near the sheath can also be observed with an imaging device disposed inside the sheath. The radiopaque marker permits accurate positioning of the sheath in the body. The sheath can be inserted into the body over an interventional device. A fastener prevents migration of a guidewire or catheter during the procedure.

Apparatus for establishing access to the body

A medical device is provided which comprises a suction conduit and an energy-transmitting conduit wherein at least some of the transmitted energy is directed to the distal region of the suction conduit. The device may include an optical apparatus for directing the energy. The device has applications in lithotripsy and tissue-removal in a patient.

A ureteral stent is configured for improved patient comfort and aftercare. The stent can have one or more of the following features: a distal portion with a somewhat flattened, non-circular cross-section that provides reduced irritation and elimination of urine reflux; a proximal portion with a helical coil shape that allows self-anchoring of the stent below the kidney; and a portion along the body of the stent having a coil shape that allows self-adjustment of the stent with ureteral movement.

A medical device for draining fluid from the body of a patient comprises an elongate member that defines a lumen and includes a proximal end and a distal portion. The device further comprises a dilating member disposed in the distal portion of the elongate member. The dilating member comprises a plurality of arms movable from a collapsed state to an expanded state in which the arms protrude radially to anchor the device within the body of the patient. The device includes a tension member that extends through the lumen to the dilating member and couples to the plurality of arms. Application of tension to the tension member causes the arms to move to the collapsed state thereby permitting insertion and removal of the device into and from the body of the patient. Some embodiments include a tension control member disposed at the proximal end of the elongate member and movable in at least a first direction and a second direction to increase and decrease tension to one or more tension members.
