Problems solved by technology

However, one of the problems associated with conventional hemostatic devices and clips is that many are not strong enough to produce permanent hemostasis
Additionally, clips have also been attempted to close perforations in gastric or GI tract structures, but unfortunately, conventional clips suffer from difficult placement and a limited amount of tissue to grasp, potentially resulting in incomplete closure

Embodiment Construction

[0034] The terms "proximal" and "distal" as used herein are intended to have a point of reference relative to the user. In particular, throughout this specification, the terms "distal" and "distally" shall mean a position, direction or orientation generally away from the user, and the terms "proximal" and "proximally" shall mean generally toward The user's location, direction or orientation.

[0035] has a T for engaging tissue ( Figure 11 ) An exemplary medical system 20 of medical devices 40 is shown in Figure 1 to Figure 4 middle. Medical system 20 and device 40 are generally sized and configured to operate through the working channel of an endoscope (not shown) or other viewing equipment, although system 20 and device 40 may also be used alone or with other elongated devices (such as catheters, fiber optic visualization systems, needles, etc.). Generally, the medical system 20 includes an actuation wire 22 slidably received within a distal end 23 of an elongate cathe...

Abstract

The present invention provides medical systems and devices for engaging tissue (T), eg, for clamping tissue (T), closing a perforation, or hemostasis. Generally, the medical system (20) includes a housing (42), a first jaw (44) and a second jaw (46) rotatable relative to the housing (42), a driver (48) and a Long drive wire (22). The elongated drive wire (22) is detachable from the driver (48), the first jaw (44) and the second jaw (46) and the housing (42), the driver, the first jaw and the second jaw The jaws and housing are left in vivo to engage tissue (T).

Description

Background technique [0001] Typically, clips may be introduced endoscopically into a body cavity to grasp living tissue of the body cavity for hemostasis, marking and / or ligation. Such clips are often referred to as small surgical clips, endoscopic clips, hemostatic clips, and vascular clips. In addition, clips are used today in a variety of applications related to gastrointestinal bleeding such as peptic ulcer, esophageal-cardia mucosal lacerations, Dieulafoy's lesions, hemangiomas, post-papillotomy bleeding and venules with active bleeding varicose. Clips have also been attempted to close perforations in the stomach. [0002] Gastrointestinal bleeding is a less common and serious condition that is often fatal if left untreated. This problem has prompted the development of various endoscopic treatment modalities to achieve hemostasis, such as injection of sclerosing agents and contact thermocoagulation techniques. Although these modalities are often effective, many patien...
