摘要： The present invention is a clinically practical, rotational angioplasty system which employs a unique rotary ablative device for mechanically abrading, and thereby removing, lesions from within a patient's vessels. The device has a gas driven prime mover connected, via a hollow helical drive assembly, to an ellipsoidal, rotating, ablative burr which is used for the actual recanalization of the patient's vessel. The burr is provided with a central opening therethrough, which, together with the hollow drive assembly, permits the burr and drive assembly to be threaded over a guide wire similar to the type conventionally used in a catheterization procedure. The drive assembly is located within a hollow sheath which prevents the rotating drive assembly from contacting the inner walls of a patient's vessel.

摘要： The present invention is a pump apparatus which is adapted to move liquids which contain debris. The apparatus is adapted to operate by alternating suction and pressure, whereby any debris which becomes lodged in any orifices or conduits in the system is effectively dislodged as a consequence of the normal operation of the system.The push-pull material transport system of the present invention includes a conduit to transport fluid from a first location to another location. The invention includes a peristaltic pump which has two heads. The first head pumps fluid from the first location to the second location, and the second head intermittently and periodically pumps fluid in the reverse direction in order to keep the conduit clear of debris.

摘要： The intralumenal material removal system includes a cutter assembly positionable in the lumen of a mammalian subject and operably connected to system controls. The cutter assembly is axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. One cutter assembly comprises an adjustable cutter that is adjustable between a smaller diameter condition and a larger diameter condition by rotation of the drive shaft in opposite directions. The cutter may thus be introduced to and withdrawn from the material removal site in a retracted, smaller diameter condition that facilitates translation and navigation of the device through various lumens. The adjustable cutting assembly may be selectively expanded at the material removal site to facilitate cutting, removal and aspiration of the occlusive material. One composite cutter assembly comprises both a distal, fixed diameter cutter and a proximal adjustable diameter cutter.

摘要： The invention is an apparatus for breaking up a thrombus by introducing a tating core wire into the thrombus whereby the fibrin of the thrombus will be withdrawn from the thrombus into the rotating core wire, thereby breaking up the network of the thrombus which prevents blood flow. The apparatus includes a drive shaft housing which can be used to withdraw fluid from the area of the thrombus or to introduce medicines, such as streptokinase which will further break up the thrombus or other chemicals such as contrast agents for visualizing the vascular anatomy. The apparatus also includes a shaft housing which is provided with an expanded catheter funnel at the distal end and a venturi insert immediately proximal to the distal end. The apparatus further includes a prime mover which, in addition to rotating the drive shaft, allows for axial motion of the drive shaft relative to the drive shaft housing.

摘要： A catheter for insertion into and treatment of tissue in a patient comprises a radio frequency (RF) electrode having an elongated body that conducts electrical RF energy to a conductive tip. An insulating sleeve surrounding the elongated body prevents leakage of RF energy from the elongated body when the catheter is being inserted into the tissue of the patient. In a first mode of operation, the conductive tip is exposed outside the insulating sleeve and the RF electrode delivers first RF energy capable of producing sparks that erode the tissue of the patient and create a tunnel through which the catheter can advance into the tissue of the patient. In a second mode of operation, the insulating sleeve is retracted to expose a portion of the RF electrode. Second RF energy is delivered to the volume of tissue around the catheter to necrotize the tissue by heating without producing sparks.

摘要： Methods and systems for securing tissues, e.g., cardiovascular tissues, are disclosed. A method in accordance with one embodiment of the invention includes inserting a portion of a catheter into an opening between a first portion of cardiovascular tissue and a second portion of cardiovascular tissue. The method can further include drawing the first and second portions of the cardiovascular tissue into contact with each other by drawing a vacuum in a region adjacent to the first and second portions of cardiovascular tissue via the catheter while the catheter is positioned between the first and second portions. The tissue portions can be fused by heating the tissue from within the opening, e.g., via radio frequency energy. This technique, and associated catheter system, can be used to close a patent foramen ovale or other openings in cardiovascular tissue.

摘要： A multipolar electrosurgical device is described for use in neurosurgery or through the channel of an endoscope or other precision surgery procedures. The device is formed with an insulative probe body, which, in the described embodiment, is sized to pass through a channel of an endoscope to enable the electrocoagulation of blood vessels such as may be needed in the treatment of a gastrointestinal ulcer. The probe body is provided with electrically separate conductors which are formed of a plurality of electrodes distributed over the peripheral surface of the probe body. The electrically separate conductors are so sized in width W and spaced from each other by a distance S as to establish a ratio of W:S which enables effective bipolar treatment of tissue independent of probe body orientation relative to the tissue and without sticking of the probe body to coagulated material. A plurality of at least six electrodes which can form six bipolar electric fields are formed which in one embodiment are aligned longitudinally on the probe body. The electrodes extend onto the probe body's distal end to provide an omnidirectionally effective electrosurgical device. A central conductive wash channel is provided for electrical connection to a set of electrodes at the distal end of the probe body while also providing a passage for fluid to enhance the visibility of the target area for subsequent precise electrocoagulation of the bleeding site. Several embodiments are shown and described.
