Problems solved by technology

About 24-48 hours after surgery, usually when the patient is normal temperature and has no coagulopathy, the packs are removed, but this usually results in clot rupture and excessive rebleeding
This rebleeding is particularly troublesome when the initial injury included, for example, a massive rupture of Gleason's capsule, as this would result in a proportionally larger area of ​​rebleeding
[0006] Currently available devices and methods for hemostatic control have certain inherent disadvantages, including but not limited to the previously mentioned problem of clot rupture

Embodiment Construction

[0019] The present invention can be further understood through the description of the following specific embodiments. The terminology used herein is only used to describe specific embodiments but not to limit the present invention.

[0020] In a specific embodiment, the present invention provides a method of treating a patient, particularly a larger mammal or human suffering from internal organ damage. In most cases, this injury will result in undesirable bleeding of the organ; however, in some cases the methods of the present invention can also be applied to other types of injury. The method includes at least partially surrounding an injured organ with a container, and applying a compressive force to at least a portion of the injured organ with the container. The container need not completely surround the organ; however, in some cases it is preferred that the container almost or completely surrounds the organ. The amount an organ needs to be surrounded depends on the specif...

Abstract

Methods and devices for hemostatic control of an injured internal organ. In one embodiment, a container is provided for at least partially surrounding an injured organ and exerting a compressive force upon the organ. Methods of treatment utilizing such devices are also provided.

Description

technical field [0001] In certain embodiments, the present invention relates to medical devices for hemostasis, and more particularly, the present invention relates to devices and techniques for inhibiting undesirable bleeding from internal organs. Background technique [0002] Bleeding from certain injuries to internal organs can present very challenging clinical management. For example, hepatic hemorrhage typically occurs after major abdominal trauma or rupture of the hepatic parenchyma caused by rapidly expanding tumors, such as those caused by adenomas, hemangiomas, or hepatocellular carcinoma. Severe hemorrhage, with accompanying hemodynamic instability, may cause or lead to an emergency in which the patient is in shock. The situation may be further complicated by secondary physical injury and the development of secondary metabolic complications including coagulopathy, severe acidosis, and hypothermia. [0003] Known techniques to control internal organ bleeding inclu...
