An assembly for externally securing a catheter at or adjacent to an exit site on a body tissue which includes a resilient member and a detachably removable and adjustable clamp which allow for a gentle bend in the catheter so that kinking is prevented.

Catheter fixation assembly

A catheter for introducing fluid into the vascular system includes ports in the catheter's sidewall which are obliquely angled with respect to the longitudinal axis of the catheter. Certain pairs of ports are oriented toward each other, and certain other pairs of ports are oriented away from each other. The arrangement of ports causes fluid to exit the ports in streams which are oriented at oblique angles corresponding to the angles of the port. The obliquely angled streams create advantageous circulation paths proximate to the catheter which generally improve efficacy of the injected fluid associated with the medical application. The catheter may be used for a variety of purposes, including to perform thrombolysis.

Catheter

An instrument for penetrating into body cavities and potential spaces in preparation for the performance of minimally invasive surgical techniques in which an indicator is provided to assist the surgeon in determining when the instrument is properly placed thereby avoiding injury to vessels and underlying structures in the body cavities and potential spaces.

Minimally invasive body cavity penetrating instruments

A locking catheter system including a flexible catheter having a restraining portion such as a pigtail, malecot rib or J-curve at its distal end and a flexible filament extending therefrom to attaching means at the other end of the catheter. The attaching means comprise a self-sealing sleeve through which the filament passes and an elastomeric sheath which encapsulates the sleeve to restrain the filament.

Locking catheter system

A surgical retractor having a plurality of widenable and narrowable blades of substantial width, having tissue-contacting surfaces that are not significantly narrower, in a collapsed position, than a guide tube for guiding the retractor blades through a surgical access port to a surgical site during a minimally invasive surgical procedure. Each retractor blade includes a relatively large, preferably planar, tissue-contacting surface for displacing or repositioning internal body tissue, such as an internal organ, for temporary displacement away from the surgical site. After insertion through a surgical access port one or more of the retractor blades can be widened laterally to substantially space distal ends of the retractor blades apart for maximum contact against and over a substantial area of the tissue to be displaced during the surgical procedure. After completion of the operative procedure, the retractor blades can be narrowed by nesting the blades together and the retractor can be easily and safely withdrawn from the access port.

Surgical retractor and surgical method

A protective tube for a laser endoscope that prevents the passage of laser smoke towards the oral cavity of a patient, removes debris from the endoscope and which is adapted to be inserted through the oral cavity and into an esophagus of a patient receiving medical treatment, the protective tube comprising a curved resilient member having a proximal end and a distal end, the proximal end including a mouthpiece and the distal end including a first sealing means and a second sealing means, the first sealing means forming a first seal between an outer surface of the tube and an inner surface of the esophagus and the second sealing means forming a second seal between an inner surface of the tube and an outer surface of the laser endoscope.
