An anchor and procedure for placing a medical implant, such as for monitoring physiological parameters. The anchor includes a central body in which a medical implant can be received. arms and members extend radially from first and second ends, respectively, of the central body. Each member defines a leg extending toward distal portions of the arms to provide a clamping action. The anchor and its implant are placed by coupling first and second guidewires to first and second portions of the anchor, placing an end of a delivery catheter in a wall where implantation is desired, inserting the anchor in the catheter with the guidewires to locate the anchor within the wall, deploying the arms of the anchor at one side of the wall followed by deployment of the members at the opposite side of the wall, and thereafter decoupling the guidewires from the anchor.

The present invention is a catheter having a tube and including mechanisms that provide precision control over insertion and retraction of the catheter tube. The catheter is particularly adapted for introduction into the pulmonary system. The catheter includes an insertion depth control mechanism that acts as a stop and provides a tactile indication to the person inserting the catheter tube that a predetermined position has been reached. The catheter also includes an anti-bunching mechanism to prevent bunching of a protective sleeve disposed around the catheter tube, thereby reducing interference from the sleeve during insertion of the catheter tube.

A loading device for facilitating the loading of a guidewire into a lumen defined by a catheter. A catheter may have a shaft extending from a proximal end to a distal end, defining one or more lumens having one or more catheter ports. A guidewire has a flexible wire-like structure extending from a proximal end to a distal end. The guidewire loading device defines a passage having a first and second loading port. A portion of a catheter may be partially inserted into one of the loading ports, such that a catheter port communicates with the loading device passage. Then, one of the guidewire ends may be inserted into the other loading port. The guidewire may be more easily inserted through the loading device passage, into the catheter port, and thus into the catheter lumen.

The invention discloses an intravascular thrombus suction catheter device and a mesh basket assembly thereof, and belongs to the field of vascular intervention medical treatment. The device comprisesa three-way connecting base, a catheter, a connecting base and a conveying sheath tube, and further comprises an expandable guide head end and a self-expansion mesh basket assembly. The self-expansionmesh basket assembly consists of a mesh basket conveying pipe, a hammer-like guide cap, a mesh basket supporting pipe and a self-expansion mesh basket, wherein the mesh basket conveying pipe is inserted into the catheter, the hollow hammer-like guide cap is arranged at the far end of the mesh basket conveying pipe, the mesh basket supporting pipe is inserted into the mesh basket conveying pipe, and the self-expansion mesh basket is fixed to the far end of the mesh basket supporting pipe. The hammer-like guide cap serving as a thrombus breaking separator is arranged at the suction opening in the head end of the far side of the catheter and used for breaking and separating thrombus blocked at the suction opening of the suction catheter; and the self-expanding mesh basket is arranged at thefar end of the lesion thrombus and used for scraping and collecting thrombus tissue attached to the wall of a blood vessel, and besides, the collected thrombus tissue is pushed to the position near the suction opening in the near end of the suction catheter.

A therapeutic or diagnostic instrument includes first and second shaped wire members and that can be simultaneously inserted into a catheter tube and has predetermined bending elasticity, in which the first and second shaped wire members and are adapted to respectively have first and second curving parts that curve in a natural state, and when inserted into the catheter tube, curve the catheter tube at two desired positions correspondingly with the first and second curving parts.

The invention discloses an epidural puncture needle insertion device for a department of anesthesiology. The epidural puncture needle insertion device comprises a fixed plate, wherein the two ends ofthe top surface of the fixed plate are fixedly connected with the same handheld U-shaped handle, a pusher bar motor is fixedly mounted on the top surface of the fixed plate, a telescopic end of the pusher bar motor penetrates through the fixed plate in a sliding manner and is fixedly connected with a needle insertion shell, both ends of the bottom surface of the fixed plate are fixedly connected with two fixed rods, compression springs sleeve the fixed rods in a sliding manner, two driving plates are mounted on the two fixed rods in a sliding penetrating manner, and the other end of each of the two driving plates is fixedly connected with the sidewall of the needle insertion shell. According to the epidural puncture needle insertion device, the handheld U-shaped handle is held by a hand, then, a sucker is sucked to skin, and then, a needle insertion region is determined, so that the stability of a puncture needle can be guaranteed, and the aching feeling of a sufferer can be reduced; and when an airbag is deflated, needle insertion is stopped, and a catheter is inserted into the puncture needle, so that a puncture result is convenient to monitor, and whether puncture is successfulor not can be known rapidly.

A system for use in treating a tissue site, e.g., a site exhibiting or at risk for developing compartment syndrome, the system including a monitor for use in controlling the function and operation of one or more apparatuses providing insertable catheters. The system includes at least one apparatus having a catheter portion that includes both a suitably protected, functional device tip, adapted to be positioned and used within the tissue site, and one or more hollow fiber membranes, e.g., an array of such membranes, adapted to be positioned within the tissue site in order to simultaneously collect fluid therefrom. The catheter portion is adapted to be safely inserted and positioned within the tissue site, in a manner that permits it to function there while substantially minimizing direct impingement of the non-fluid tissue on the functional device tip surface.

An in-line sampling syringe for selectively introducing and aspirating a fluid from a downstream fluid conduit connected to a catheterized patient. The syringe includes a housing with a distal component defining a distal chamber having a proximal opening and a distal outlet port to be coupled to a downstream fluid conduit; and a pair of proximal wall components assembled together in an airtight manner defining a proximal chamber having a proximal opening for coupling to an external source of fluid and a distal opening that is coupled to the proximal opening of the distal component. The syringe also includes an elongated volume regulator positioned inside the housing. A curved element is positioned at and in alignment with the distal outlet and retention elements are defined in the distal component at the distal outlet port to mount and retain the curved element at the distal outlet port while enabling flow around the curved element relative to the distal outlet port. A conduit extends from the proximal opening of the proximal chamber through the elongated volume regulator to the curved element at the distal outlet port.

The invention discloses a large channel straight-through endoscope, comprising: an insertion part, including an insertion catheter and a tip head fixed at the front end of the insertion catheter; an operation part, connected to the end of the insertion part, including a handle and a certain angle with the handle The handle of the handle; the rear end of the handle of the operating part is provided with an instrument inlet, the inside of the handle and the inner cavity of the insertion catheter are pierced with an instrument catheter, and the acute angle between the section axis of the instrument inlet and the section axis of the instrument catheter in the handle is less than 15 degrees. The large channel of the present invention leads directly into the endoscope, and the optical fiber does not need to be bent during the process of extending from the instrument entrance into the instrument channel, which effectively avoids damage to the optical fiber. The instrument is inserted into the instrument catheter for operation at the same time, which shortens the operation time, improves the operation efficiency, and has high practical value.
