Novel peripheral vessel intervention exchange sheath

Abstract

The invention provides a novel peripheral vessel intervention exchange sheath. Compared with the traditional catheter sheath, a small balloon is designed at the far end of a sheath tube, the sheath tube is fixed in a punctured blood vessel after the balloon dilatation, and by adjusting the position of a catheter sheath, the lesion towards two directions, namely the near end and the far end, of the ilio-femoral artery can be simultaneously treated, therefore, the puncture times of patients is reduced, and the treatment effects are improved; compared with a two-cavity catheter sheath, the three-cavity catheter sheath provided by the invention has the advantage that one function cavity is added, and therefore, two sets of intervention medical apparatuses can be simultaneously introduced into the near end or the far end.

Description

technical field [0001] The invention relates to an interventional treatment appliance, in particular to a catheter exchange sheath for interventional treatment of intracavitary vascular diseases. Background technique [0002] At present, in the treatment of cardiovascular diseases, interventional therapy has been widely used because of its advantages of less bleeding, less trauma, fewer complications, safety and reliability, and quick postoperative recovery. Interventional treatment often requires frequent and continuous delivery of therapeutic fluids or medical devices into the patient's body. The catheter sheath is a channel for inserting various medical devices into the patient's body cavity or blood vessel. Puncture a relatively small The catheter sheath is inserted into the puncture hole, and the doctor can transport the therapeutic liquid or medical device to the place where it is needed in the blood vessel through the end of the catheter sheath that is inserted outsid...

Problems solved by technology

However, the existing introducer sheaths on the market only have one inlet and one outlet, which limits that one puncture site can only treat vascular lesions in one direction, which not only makes most patients with vascular diseases have to undergo two or even multiple treatments clinically. Interventional surgery, and it also greatly reduces the therapeutic effect; at the same time, for patients with antegrade puncture of the femoral artery, the guide wire can easily enter the deep femoral artery, making the operator have to puncture multiple times to place the guide wire into the superficial femoral artery, which increases the The probability of damaging the punctured artery significantly increases the occurrence of complications related to the puncture point, such as pseudoaneurysm, arteriovenous fistula, etc.
