摘要： Flexible microcatheter having regions of different flexibility integrally and strategically placed along and about the length of a one-piece composite catheter tube. Distally the flexible microcatheter exhibits pronounced flexibility with respect to locations or regions of flexibility located proximally for navigation along tortuous vascular paths. Different regions of flexibility are formed by applying resins of different Shore hardness readings either singularly or in combination along and about a braid which overlies an inner resin layer. The encapsulated braid provides resistance to kinking and bending of the flexible microcatheter as well as providing for torque transmission and pushability along the length of the flexible microcatheter.

摘要： A rheolytic thrombectomy catheter and method of using same to remove thrombus from a body vessel or other body cavity. Several embodiments are disclosed. All embodiments include an outer catheter having a lumen and an inner high pressure tube of a size to enable it to be passed through the lumen of the catheter. The distal end of the inner high pressure tube extends beyond the distal end of the catheter and carries a jet cap for directing one or more jets of saline proximally toward the distal end of the catheter. In some embodiments, the catheter has a distally located inwardly directed stationary stop and the inner high pressure tube includes a distally located outwardly directed transitional stop for engaging the inwardly directed stationary stop to thereby position the jet cap at a defined distance from the distal end of the catheter. In other embodiments, a stationary stop is located at the proximal end of the catheter and a transitional stop is carried on the proximal end of the inner high pressure tube. In the embodiments having the stationary and transitional stops located proximally, the inner high pressure tube includes a flow director at its distal end. In use, thrombus is dislodged, entrained, and broken into pieces by the saline jets and evacuated proximally through the lumen of the catheter.

摘要： A surgical device and method for removal of tissue, such as thrombus, from a vessel in the body. The device has a first tube with a distal open end and an inward directed stop and a second tube with an outward directed stop for engaging the inward directed stop and thereby regulating the relationship between a retrograde jet and the distal open end. Thrombus is dislodged, entrained, and broken into pieces which are evacuated through the first tube.

摘要： A miniature cross stream thrombectomy catheter useful in small blood vessel thrombectomy procedures. An annulus near the distal end of the miniature cross stream thrombectomy catheter is formed between a hypo-tube and a proximally directed bore of a concentrically aligned flow director whereby jet orifices in the hypo-tube communicate with the annulus to direct jet flows of saline or other fluid around and about the annulus and to be directed proximally from the annulus to pass through one or more outflow orifices and thence to pass through one or more inflow orifices thereby creating an ablation flow therebetween which loosens and carries away thrombotic materials from the walls of a blood vessel.

摘要： A tubular guidewire assembly having a distal occlusive device and an extended crimpable section proximate a proximal end that is adapted to connect to a gas inflation/evacuation system. The extended crimpable section can be selectively sealed at one of a plurality of separate locations to form an airtight seal of the tubular guidewire assembly. Each time a deflation of the occlusive device is desired in order to reestablish blood flow to a vessel downstream of the occlusive device, the extended crimpable section preferably is cut distal to the location of the last seal to quickly deflate the occlusive device.

摘要： A thrombectomy catheter system with occluder and method of using same for removal of tissue, such as thrombus and the like, from a vessel in the body. Multiple catheters and an occluder-bearing guidewire tube at a thrombus site provide for expandable deployment of a compliant occluder against the vasculature walls distal to the thrombus. The expanded occluder is maneuvered proximally to urge thrombus into close proximity with a retractable capture cone located distally on a capture catheter where the thrombus is dislodged, entrained, and broken into pieces by the action of a fluid jet emanator and then evacuated through the capture catheter.
