Description

Surgical guide peristaltic balloon catheter capable of hemostasis {balloon catheter}

The present invention relates to a surgical guide peristaltic balloon catheter capable of hemostasis. Specifically, the present invention changes the position of the balloon according to the change in the position of the guide part by the operation part, the tube and the guide part has a flexible feature, and when the amount of gas injected into the tube is specified in advance, input The part relates to a balloon catheter, characterized in that only gas corresponding to a predetermined amount is introduced into the inside of the tube, and hemostasis is possible.

The sinus is a hollow cavity within the skull that is connected to the nasal cavity by small openings known as vesicles. Each pore between the sinuses and the nasal cavity is formed by the bone covered by a layer of mucous tissue. Usually, air passes through the pores into and out of the sinuses. In addition, mucus continues to be formed by the lining of the mucous membrane of the sinuses, and is discharged through the pores and into the nasal cavity.

Sinusitis is a general term referring to inflammation within one or more sinuses. Acute sinusitis can be associated with an infection or allergic disease that can lead to tissue swelling and temporarily impede normal tracheal-passage and ventilation of the sinuses, resulting in some accumulation of mucus and possibly infection in the sinuses. . Chronic sinusitis is an organ disease characterized by persistent narrowing or blockage of one or more sinus vesicles, causing chronic infection and inflammation of the sinuses. Chronic sinusitis is often associated with prolonged respiratory allergies, nasal polyps, hypertrophic turbinates and/or septal curvature. Acute sinusitis is typically caused by infection with a single pathogen (e.g., one type of bacteria, one type of virus, one type of fungus, etc.), whereas chronic sinusitis is caused by infection with multiple pathogens (e.g. For example, more than one type of bacteria or more than one type of microorganism) is often associated.

Chronic sinusitis, if left untreated, can lead to irreparable damage to the tissue and/or bone structures of the sinus anatomy. The initial treatment of chronic sinusitis usually involves the use of drugs such as decongestants, steroid nasal sprays, and antibiotics (if the infection is bacterial). If cure has failed with drug treatment alone, surgical intervention may be recommended.

The most common surgical procedure for treating chronic sinusitis is functional endoscopic sinus surgery (FESS). FESS is generally performed using an endoscope and various rigid instruments inserted through the patient's nostrils. Endoscopy is used to visualize the positioning and use of various rigid instruments used to remove tissue from the nasal cavity and sinus vesicles in an attempt to improve sinus drainage.

A technique known as Balloon Sinuplasty procedure and a system for performing this procedure was developed by Acclarent Inc, Menlo Park, Calif., USA for the treatment of sinusitis. A number of U.S. patents and patent applications, including U.S. Patent Nos. 7645272, 77654997, and 7803150, describe various embodiments of balloon sinusplasty procedures, as well as various devices that can be used to perform such procedures. In balloon sinusplasty procedures, a guide catheter is inserted into the nose and placed in or adjacent to the pore of the affected sinus. A guidewire is then advanced through the guide catheter and into the affected sinus.

Thereafter, an expansion catheter with an expandable dilator (eg, an expandable balloon) is advanced over the guide wire to a position where the dilator (balloon) is located within the pore of the affected sinus. The dilator is then enlarged, causing the expansion of the pore and remodeling of the bone adjacent to the pore without requiring an incision of the mucosa or any bone removal. The catheter and guidewire are then removed, and the dilated pore allows for improved drainage and ventilation of the affected sinus.

After performing a FESS or balloon sinusplasty procedure, it may be useful or necessary to flush the sinuses. The device described in US 2008/0183128 can be used to clean the sinuses. The washing catheter can be advanced through the guide catheter and into the pore or sinus, for example, for the purposes of washing, aspiration, mass transfer and culture recovery.
