Abstract: An electrosurgical device is provided for removing polyps from the gastrointestinal tract of a patient. In one implementation, an electrosurgical device comprises a snare support member and a snare positioning assembly mounted on an exterior surface of the snare support member. The snare positioning assembly has a longitudinal axis substantially parallel with and offset from the longitudinal axis of the snare support member. The device also includes a base member attached to a distal end of the snare support member and has a longitudinal axis substantially aligned with the longitudinal axis of the snare support member. An aperture is formed through a side wall of the base member. Also included is a polyp snare extending through a first channel of the snare positioning assembly, through the aperture, and through a second channel of the base member.

Abstract: A medical device and related methods of use are provided for capture and removal of tissue from body lumens. The device includes an end-effector unit configured to capture tissue, having a distal end and a proximal end. The distal end and the proximal end form a substantially closed structure, and the distal end is more flexible than the proximal end. The device also includes a control member at the proximal end for holding and controlling the severing device.

Abstract: Described are expanded collagenous materials useful in hemostatic applications. Certain expanded collagenous materials can be prepared by treating a first collagenous material with an alkaline substance under conditions effective to expand the first collagenous material, recovering the expanded material, processing the expanded material to provide a foam, and chemically crosslinking the foam. Expanded materials can exhibit beneficial resilience, persistence and tissue generation characteristics when implanted, and can be used in the formation of highly porous medical implant bodies which can be compressed to fractions of their original volume and will thereafter substantially recover their original volume.

Abstract: The invention describes a disposable device for operations on the arteria haemorroidalis, which comprises a retractor tube (1), closed and rounded on the end (101) which is inserted in the anal cavity, and open and diverging on the external end (201) to which is connected a griping handle (M) which removable houses a luminous source (F). In the connection zone of the handle to the external mouth of the retractor there is provided a channel (C) which contains a parabola (5) which reflects the light supplied from said luminous source (F) and which sends the reflected light inside of the same retractor, to illuminate a lateral window (8) through which appears the rectal mucosa upon which the operation must be made for the ligature of the arteria haemorroidalis.

Abstract: A handle for a medical device comprises a frame, a transmission, a slide, a first rack, a sheath, and a cable assembly. The transmission is mounted to the frame. The slide is moveably attached to the frame and coupled with the transmission. The first rack is moveably attached to the frame and coupled with the transmission. The sheath is secured to the first rack. The cable assembly is secured to the frame and extends through the sheath.

Abstract: A surgical instrument assembly for the treatment of hemorrhoids includes an anoscope and a hemorrhoid occlusion device. The anoscope includes a hollow body closed at a distal end and at least partially open at a proximal end to define a longitudinal channel. The hollow body has a sidewall provided with a window spaced from the distal end and the proximal end. A shutter member is slidably attached to the hollow body for selectively covering the window during an insertion operation and for opening the window to allow hemorrhoidal tissues to protrude through the window into the anoscope. The hemorrhoid occlusion device includes an instrument shaft provided at a distal end with two jaws, at least one of the jaws including a C- or U-shaped clamping member movable alternately away and towards the other of the jaws for clamping and occluding hemorrhoidal tissues protruding through the window into the anoscope.

Abstract: This invention relates to novel methods, kits, and devices for stopping hemorrhaging of percutaneous wounds. The inventive subject matter involves insertion of a purse-string suture around the wound, insertion of the free two ends of the suture through a tension collar, manual tightening of the tension collar until hemostasis is achieved, and application of a suture lock to the free ends of the suture to secure the tension collar and maintain hemostasis. After a sufficient period of time to allow complete hemostasis, the suture lock and the tension collar are loosened; if hemostasis has been achieved, the suture lock, the tension collar, and the suture material are removed. If bleeding continues from the wound, the tension collar is tightened and the suture lock reapplied. This process may be repeated until complete hemostasis is achieved, without the need for additional suturing or manual compression.

Abstract: A cardiac constraint jacket is formed of flexible material defining a volume between an open upper end and a lower end. The jacket is dimensioned for an apex of a patient's heart to be inserted into the volume through the open upper end and for the jacket to be slipped over the heart. The jacket includes a receiving member along its upper end for engagement to a delivery apparatus, the apparatus used in positioning the jacket on the heart. The delivery apparatus includes a handle and a band. The band is generally hoop shaped having a first end and a second end attached to the handle, the first end fixedly attached to the handle and the second end releasably attached to the handle. Alternatively, the first end can be attached to a releasable end cap of the handle. In use, the second end of the band is released from the handle and inserted into the jacket receiving member. The jacket is threaded onto the band and the band end re-attached to the handle.

Abstract: Medical devices for filtering fluids flowing through a lumen and a method of forming medical devices. The devices can be used in vascular channels, urinary tracts, biliary ducts and the like, and filter emboli and other debris generated at a treatment site.

Abstract: The invention describes a method of treating a patient's left atrial appendage through the pericardial space. The process takes place through the pericardial space from an access point outside the pericardium or pericardial space.

Abstract: The present invention provides a bipolar coagulator which can be passed through the internal lumen of a ventricular catheter previously implanted into a cranial ventricle of a living subject and engaged in-situ. The bipolar coagulator will provide bipolar electrical arc currents for coagulation cauterization of adherent brain tissues, such as the choroid plexus, which occludes fluid flow into the intake drainage holes in the implanted ventricular catheter and often becomes adherent to the catheter in-situ. The cautery current provided by the bipolar coagulator is direction oriented and spatially controlled; thereby providing a better distribution of electrical current and heat within the surrounding cranial tissues; and thereby avoiding major complications of damage to intracranial structures such as blood vessels as well as avoiding the severe subarachnoid hemorrhages which are typical using other kinds of coagulation instruments.
