A transvascularly placed steerable microcatheter, further including internal steerability and the ability to articulate in a direction at right angles to its longitudinal axis at or near its distal end. The steerable microcatheter is generally fabricated from stainless steel, nitinol, or other metal and includes an outer tube, an inner tube, hub structures, and a distal articulating region. The steerable microcatheter can be advanced through a body lumen in its straight configuration and then be selectively articulated or curved to permit negotiation of tortuous curvature. The microcatheter is especially suited to robotic or powered control applications with user intervention or using artificial intelligence (AI).

Steerable microcatheter and method of use

An endoluminal punch and introducer sheath are described wherein the endoluminal punch comprises a guidewire lumen through which a user is capable of placing a guidewire. The endoluminal punch system further comprises a mechanism affixed to the hub which is capable of controlling the axial positioning of the guidewire relative to the endoluminal punch distal end. The control mechanism can be released so that the endoluminal punch can be removed from a patient while retaining the guidewire in place within the patient. The endoluminal punch introducer, including a sheath and dilator, can comprise energy emitting electrodes or transducers for cutting larger size holes in stubborn (friable, scarred, or fibrotic) tissue. In other embodiments, the endoluminal punch can comprise a guidewire or stylet, wherein the guidewire or stylet is capable of emitting energy to cut through tissue.

Surgical bolts are useful for solid visceral wound hemostasis. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts bring the tissue into apposition and hold said tissue in apposition while the wound heals. These bolts, or soft tissue rivets, overcome the limitations of sutures that are currently used for the same purposes. The devices are flexible, bendable, and conformable in their wet or dry state. The bolts include pressure plates that are capable of exerting compressive pressure over broad areas of visceral wounds without causing tearing of the friable parenchyma. The bolts are placed and removed by open surgery or laparoscopic access. The bolts can be placed into tissue where both sides of the bolt are exposed, or they can be placed blindly into tissue where the bolt does not protrude out of the tissue at its distal end.

Devices and methods are disclosed for achieving control and stabilization of bone fractures in mammals, most specifically humans. Stabilization and traction is often required to support fractured bones of the arms or legs. The devices and methods disclosed herein are especially useful in the emergency or military setting. The devices utilize a collapsible, inflatable member that is expanded and locked into position. The frame or inflatable member is fabricated primarily from polymeric materials with low radiodensity. The limb contact regions are adjustable to fit a wide variety of limb sizes and fracture locations. The traction applied by the splint is adjustable, controllable and measurable. The traction splint is compact and will fit in a compartment of most emergency rescue vehicles, thus making it more available for use than standard traction splints used today. The traction splint is either a separate device or integrated into a backboard.

Splint system and method of use

Devices and methods are disclosed for achieving hemostasis in traumatized patients. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. The patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices come in a variety of configurations including sheet, rolled sheet, folded sheet and polygonal solids including extruded shapes. The devices are capable of serving as carriers for thrombogenic or anti-pathogenic agents. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding, and may further comprise antimicrobial or thrombogenic regions.

Method and apparatus for hemostasis

A device and method for achieving hemostasis and leakage control in vascular structures and other body ducts or vessels in an emergency room or trauma situation. The device has at least one shunt that contains an obturator on an end of the shunt. The shunt is inserted into a damaged vessel or lumen for sealing the leak or hemorrhage. Two shunts that both contain obturators on one of their ends can be inserted into two different vessels or lumens when the vessel or lumen has been severed. The obturators allow for the improved ease of insertion into the vessel or lumen. The two shunts are then releasably attached to restore fluid communication through the vessel or lumen. The shunt is placed temporarily within the patient and then removed when definitive repair can be achieved by a qualified physician.

Method and device for temporary emergency vessel anastomoses

Devices and methods are disclosed for achieving hemostasis in traumatized patients. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. In such cases, the patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. Peripheral haemostatic packing devices include optional adhesive structures to attach one packing device to another. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding. The devices can be inserted into a wound and filled with fluid, gel, or particulates through an axially elongate tube to generate pressure to tamponade the wound.

Devices and methods for achieving hemostasis and leakage control in hollow body vessels such as the small and large intestines, arteries, and veins as well as ducts leading to the gall bladder and other organs. The devices and methods disclosed are especially useful in the emergency, trauma surgery or military setting, and most especially during damage control procedures. In such cases, the patient may have received trauma to the abdomen, extremities, neck or thoracic region. The devices utilize removable or permanently implanted, broad, soft, parallel jaw clips with minimal projections to maintain vessel contents without damage to the tissue comprising the vessel. These clips are applied using either standard instruments or custom devices that are subsequently removed leaving the clips implanted, on a temporary or permanent basis, to provide for hemostasis or leakage prevention, or both. These clips overcome the limitations of clips and sutures that are currently used for the same purposes. The clips come in a variety of shapes and sizes. The clips may be placed and removed by open surgery or laparoscopic access.

Method and apparatus for vascular and visceral clipping

Devices and methods are disclosed for achieving hemostasis in patients who have received skin-penetrating wounds to the periphery, including the head, arms, and legs. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery, or military setting. The devices utilize fluid impermeable barriers surrounded by exterior dams and pressure to achieve tamponade and hemostasis, primarily by exertion of force to hold the dams against the skin surrounding a wound. The devices are capable of serving as carriers for thrombogenic, antimicrobial or antipathogenic agents. The devices do not require the use of adhesives to work as they are attached to the patient using mechanical locking devices. Peripheral haemostatic packing devices include optional adhesive hemostatic barriers to attach at least a portion of the device to the skin or to assist with initial coupling of a hold-down strap to another strap using a more secure mechanical lock. The peripheral hemostatic packing system does not completely surround the extremity having the wound and therefore do not cause a tourniquet effect. The peripheral hemostatic packing system preferably is held against the skin surrounding a wound by a force that is generally unidirectional and substantially perpendicular to the plane in which the skin of the wound resides.
