Problems solved by technology

The existing thrombus capture catheters have their own advantages and disadvantages. Because of their insufficient flexibility, they can capture thrombus in larger blood vessels better, but it is difficult to enter the tortuous intracranial blood vessels and difficult to implement.

Embodiment Construction

[0024] Please refer to Fig. 1, 2, the device of embodiment 1 of the present invention comprises: guide wire 1, filter 2, tubular cross wire 3, connector 4, traction guide wire 5, balloon 6, multi-balloon catheter 7, guide wire Through hole 8 and housing conduit 12 . The guide wire 1 can pass through the thrombus or exfoliated arteriosclerotic plaque or other emboli to reach the distal end of the thrombus far enough; the multi-balloon catheter 7 follows up the guide wire, passes through the thrombus and reaches the distal end of the thrombus far enough, and The proximal balloon should be located at the proximal end of the thrombus; the thrombus capture device includes a distal filter 2 and a tubular cross mesh 3 connected thereto. The distal end of the balloon catheter 7 is inserted into the thrombus along with the balloon catheter 7, the balloon 6 is inflated, the tubular cross mesh 3 and the filter 2 are expanded thereupon, the thrombus is compressed into the space between th...

Abstract

The invention discloses a device for crushing and taking-off thrombus. The device comprises a conducting wire, a crossing mesh, a strainer, a draught device, a multi ball bag conduct pipe and a casing conduct pipe. A plurality of ball bags are arranged in series on the soft part of the far end of the multi ball bag conduct pipe; the crossing mesh and the strainer are sleeved through compression on the far end of the ball bag conduct pipe and covered on the ball bags, the ball bags are filled, the crossing mesh and the strainer are pulled off, and the thrombus or other emboli in the small blood vessel is crushed and taken off.

Description

technical field [0001] The present invention relates to devices for comminuting and removing fresh thrombus, atherosclerotic plaque or other objects within blood vessels or other anatomical passages. Background technique [0002] With the improvement of living standards, the incidence of cardiovascular and cerebrovascular diseases has increased year by year, becoming one of the three major causes of death in humans. Among them, the morbidity, prevalence, mortality, disability and recurrence of cerebrovascular diseases are all high. The main results of the epidemiological survey of cerebrovascular diseases in China are as follows: Incidence rate: 136-441 / 100,000 population / year (1.632-15.292 million / year), of which cerebral infarction accounts for 75% of stroke; prevalence rate: 280 ~1285 / 100,000 population (3.36-15.292 million / year); mortality rate: 59-281 / 100,000 population / year (70.8-3.372 million / year) average 1.30 / 100,000 / year (1.56 million / year); Disability rate: 60-8...
