摘要:
A wire guide holder having a body for securing an elongate medical wire or tube, such as a wire guide or catheter. The body is adapted to be attached to a scope or a bite block. The body can be provided with protrusions and/or grooves for holding a wire guide. The wire guide holder may be affixed to the medical scope by clamping. The wire guide holder can also be provided with a seal.
摘要:
A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A system of indicia, such as radiopaque or viewable markers, permit the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc., can be introduced to perform a second medical operation without a traditional over-the-wire exchange being required. In another example of the method, a prosthesis, such as a valve or stent, is placed within the work site coupled to a wire guide which is remotely disconnected within the work site and a secondary device, such as a dilation balloon or second prosthesis, is introduced into the work site after the first delivery system is removed.

摘要:
An elongate catheter shaft having a side port aperture through a side wall of the catheter shaft between proximal and distal ends of the shaft. The side port aperture is open to a lumen. Embodiments of the present invention are directed to stiffening structure disposed in the immediate vicinity of the side port aperture. The stiffening structures may be disposed on or be continuous with, for example, an exterior surface, an interior lumenal surface, within a wall of the catheter shaft, or some combination thereof. The stiffening structures described herein are directed to biasing the catheter shaft in the region of a side port aperture in a straight or curved configuration that resists undesired flexure in the region of the side port aperture.

An endoscope securing and positioning device is provided for adjusting or maintaining the position of an endoscope. The device allows the medical professional to easily rotate an endoscope or maintain its position without having to maintain a grip on the endoscope.
摘要:
An endoscopic ultrasound-guided system and method for monitoring the location of a device contained within intraluminal and extraluminal regions of a patient is described. The endoscopic ultrasound-guided system includes a linear echoendoscope, a device, and a wire guide. The device and wire guide contain echogenic surfaces which enable transducers placed at the distal end of the linear echoendoscope to ultrasonically monitor the location of the devices. When the echogenic surface of the device encounters incident ultrasound waves emitted from a series of linear array transducers, a real-time ultrasonic image of the device is generated as the incident ultrasound waves reflect off the echogenic surfaces and propagate back towards the transducers. The surgeon receives the real-time ultrasonic image of the device and then can determine the location of the device within the intraluminal or extraluminal region of the patient. After determining the location of the device, the surgeon can adjust the path of the device to ensure it is guided to the target site.

A device and method for accessing the interior of a cavity of a patient is described. The transmural access system includes an overtube for use with an endoscope, a safety trocar, suture anchors, and a suture exchanger. The overtube is deployed in conjunction with an endoscope through a selected body passageway of a patient to locate a sight for an access portal. The distal end of the multi-lumen overtube is secured to an interior body wall of the selected access portal. A safety trocar is advanced through the main lumen of the overtube to form the access portal to the body cavity. Upon completion of the desired medical procedure, the access portal can be closed by deploying a suture exchanger.
摘要:
A minimally invasive medical device, including an elongate shaft that has a helical color pattern of at least an alternating first color band having a first width and second color band having a second width. Along a surface parallel to a central longitudinal axis of the shaft, a length interval between each of a plurality of occurrences of the first color band is sufficiently uniform to allow use for measurement.
