The example thrombectomy catheter includes a catheter tube including a proximal portion, a distal portion and a lumen extending therein. The thrombectomy catheter also includes a high pressure tube extending through the catheter lumen from the catheter proximal portion toward the catheter distal portion, the high pressure tube having at least one jet orifice for directing at least one fluid jet through the catheter lumen. The thrombectomy catheter also includes an outflow orifice, an inflow orifice and a fluid pulse generator coupled to the proximal portion of the catheter tube, wherein the fluid pulse generator is configured to inject fluid though the thrombectomy catheter at a first frequency. ## Claims ### Claim 1 A thrombectomy catheter, comprising: a catheter tube including a proximal portion, a distal portion, and a lumen extending therein; a high pressure tube extending through the catheter lumen from the catheter proximal portion toward the catheter distal portion, the high pressure tube having at least one jet orifice for directing at least one fluid jet through the catheter lumen; an outflow orifice; an inflow orifice; and a fluid pulse generator coupled to the proximal portion of the catheter tube; wherein the fluid pulse generator is configured to receive a fluid flow and modify the received fluid flow into a pulsed fluid flowing through the thrombectomy catheter at a first frequency; wherein the first frequency is 20-30 MHz. ### Claim 2 (depends on 1) The thrombectomy catheter of claim 1, wherein the first frequency approximates a resonant frequency of a target site. ### Claim 3 (depends on 1) The thrombectomy catheter of claim 1, wherein the fluid pulse generator is configured to receive the fluid flow at a second frequency different from the first frequency. ### Claim 4 (depends on 1) The thrombectomy catheter of claim 1, wherein the first frequency is within 5% of the resonant frequency. ### Claim 5 (depends on 1) The thrombectomy catheter of claim 1, wherein the first frequency is less than or equal to 30 MHz. ### Claim 6 (depends on 1) The thrombectomy catheter of claim 1, wherein the first frequency is 23-27 MHz. ### Claim 7 (depends on 1) The thrombectomy catheter of claim 1, wherein the fluid pulse generator includes a fluid inlet portion, a fluid outlet portion, and a frequency modulating portion extending therebetween. ### Claim 8 (depends on 7) The thrombectomy catheter of claim 7, wherein the frequency modulating portion includes a disruptor, and wherein the disruptor is intended to disrupt the flow of fluid through the fluid pulse generator. ### Claim 9 A thrombectomy catheter, comprising: a catheter tube including an inlet portion, an outlet portion, and a lumen extending therein; and a fluid pulse generator coupled to the inlet portion of the catheter tube; wherein the fluid pulse generator is configured to receive a fluid flow and modify the received fluid flow into a pulsed fluid flowing through the lumen of the catheter tube at a first frequency of 20-30 MHz. ### Claim 10 (depends on 9) The thrombectomy catheter of claim 9, wherein the first frequency approximates a resonant frequency of a target site. ### Claim 11 (depends on 9) The thrombectomy catheter of claim 9, wherein the fluid pulse generator is configured to receive the fluid flow at a second frequency different from the first frequency. ### Claim 12 (depends on 9) The thrombectomy catheter of claim 9, wherein the first frequency is 23-27 MHz. ### Claim 13 (depends on 9) The thrombectomy catheter of claim 9, wherein the fluid pulse generator includes a fluid inlet portion, a fluid outlet portion, and a frequency modulating portion extending therebetween. ### Claim 14 (depends on 13) The thrombectomy catheter of claim 13, wherein the frequency modulating portion includes a disruptor, and wherein the disruptor is intended to disrupt the flow of fluid through the fluid pulse generator.
