A balloon-type electrode catheter according to the present invention includes an outer tube, an energizing connector, a balloon including neck portions on both ends of an expansion portion, an inner tube, a distal end tip, strip electrodes formed on an outer surface of the balloon, a metal ring attached to the distal end side neck portion with a distal end portion of each of the strip electrodes secured to an outer circumferential surface of the metal ring, and a lead wire electrically connecting each of the strip electrodes and the energizing connector with a distal end of the lead wire fixed to an inner circumferential surface of the metal ring and with a proximal end of the lead wire fixed to the energizing connector.

The invention comprises an indwelling medical device which is capable of delivering a therapeutic agent evenly along the length of the indwelling portion, including the outer wall, of the device.

The embodiments described herein relate to a self-positioning, quick-deployment low profile transvenous electrode system for sequentially pacing both the atrium and ventricle of the heart in the “dual chamber” mode, and methods for deploying the same.

An ultrasound catheter and an ultrasound catheter system that can acquire an image of an observation target with high accuracy when inserted into a large inner lumen. An ultrasound catheter includes: an outer sheath having an accommodation lumen; an inner sheath that can move along an axis; a drive shaft that can rotate in the inner sheath and the outer sheath; and a transducer that is disposed in the accommodation lumen and fixed to a distal end of the drive shaft. The outer sheath includes a first bent portion bent and shaped in advance at a predetermined angle on a proximal side of a most distal end of the accommodation lumen, and a first tubular portion and a second tubular portion positioned on a distal side of the first bent portion and on the proximal side of the most distal end of the accommodation lumen.

An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.

Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

An assembly for redirecting light emitted by an end-emitting optical fiber into an inner lumen of a body is provided. According to one implementation, the body includes one or more surfaces disposed on or in the body onto which the light is configured to impinge when the end emitting optical fiber is activated, the one or more surfaces being configured to alter the trajectory of the light so that the light is directed to impinge on a light reflector of a cap removably attached to the body, the light reflector of the cap being configured to redirect the light distally into the inner lumen of the body.

An introducer sheath for the insertion of a medical device into a blood vessel having an expandable sheath. The sheath has a length, a thickness, and proximal and distal ends. The expandable sheath has a frame extending longitudinally between the proximal and the distal ends, and having an exterior surface and an interior surface that forms an interior lumen along the length of the frame. The frame is configured to achieve an expanded state and a contracted state, the expanded state forming an expanded cross-section in the lumen for passing a medical device therethrough. The frame has a smooth coating about the exterior surface and protrusions extending into the lumen along the interior surface. The introducer sheath can be introduced into a patient in the contracted state, with the distal end of the introducer sheath prevented from moving in the proximal direction by an abutment against a dilator end surface.

An improved bi-directional steerable catheter is provided. The catheter generally comprises a catheter body, tip section and control handle. The catheter further comprises first and second puller wires extending from the control handle, through the catheter body and into the tip section. The control handle has deflection means for each puller wire that include a gear, and a carrier to which the proximal end of a puller wire is anchored. The gear is rotatably coupled to a lever controlled by an operator and the gear engages the carrier such that rotation of the gear by the lever results in longitudinal movement of the carrier, which results in deflection of the tip section.

A catheter assembly is constructed by reflow bonding an inner liner and an outer layer. The inner liner defines at least one lumen. The inner liner is made of a gamma-irradiated polymeric material that includes a polyether block amide and a gamma radiation activated cross-linking agent.
