A method for automatically detecting a clinically relevant leak and/or inadequate closure following a medical procedure, in a hollow organ residing in the interior volume of a body cavity. The test method includes the steps of: injecting, via an adapted injection element, a specific test gas or a gas mixture containing at least one test gas, into the organ, analyzing the gas mixture and measuring the test gas concentration in the interior volume of the body cavity via an adapted detection element and at least during a measurement window, evaluating the likelihood of the presence of a leak and its degree of severity, by comparing stored data and real-time data with each other. The pressure difference between the interior of the hollow organ(s) and the interior volume of the body cavity is controlled or mastered at least at a given moment during at least one measurement window.

A medical implant comprises a central flow portion having a first network of struts forming two or more cells, a first set of anchoring arms, and a second set of anchoring arms. The two or more cells are arranged linearly and extend from the first set of anchoring arms to the second set of anchoring arms.

A reversible vasectomy device suitable for reverse vasectomy operations is presented. More specifically, the present invention may take the form of a stent device that installs along the severed vas deferens such that the vas deferens ends are opened and coupled together. The reversible vasectomy device is made out of an absorbable material, allowing the reversible vasectomy device to be absorbed by the body, leaving only the connected vas deferens once the healing process is completed. The reversible vasectomy device contains a first connection element, a second connection element, and a mid-section. The mid-section is connected between the first connection element and the second connection element. The first connection element, the second connection element, and the mid-section are in fluid communication with each other.

Disclosed are a lead method of suturing an acutely ruptured Achilles tendon and a device used in it. The suturing device includes a suture line, guide lines, a clamping instrument and suture needles. As performing suturing, the clamping instrument is inserted into the fascia sheath of Achilles tendon to clamp Achilles tendon, the suture line and the guide lines are made to penetrate Achilles tendon and skin through the threading hole on the clamping instrument by the suture needle, wherein the suture line is located far away from Achilles tendon rupture; the guide lines are used to guide the suture line, so that both ends of the suture line can penetrate Achilles tendon in turn along the guide lines, and the suture line is tightened and knotted on the two ruptured Achilles tendons.

A medical device assembly includes a hinge rod having a first portion and a second portion, and a pedestal is coupled to the second portion of the hinge rod, the pedestal having a top surface, and portions of the pedestal cooperate to define a trough that is configured to hold a first portion of a vessel on the top surface of the pedestal. A retainer is movably coupled to the pedestal, and the retainer has a planar member having a lower surface configured to oppose the top surface of the pedestal. A joint member is coupled to the hinge rod, and a clamp assembly is releasably coupled to the joint member such that when the clamp assembly is in a locked configuration, the hinge rod is not repositionable, and when the clamp assembly is in an unlocked configuration, the hinge rod is repositionable.

Devices and methods for increasing a patient's pulmonary arterial compliance are disclosed. The devices include catheters designed to create a connection between a patient's venous anatomy and the patient's pulmonary artery. With the arteriovenous connection various devices can be implanted in order to increase the volumetric compliance of the pulmonary artery. The devices include collapsible and expandable mechanisms which allow the effective pulmonary arterial volume to expand during systole and contract during diastole. The devices may include a balloon or balloon-like implants which cyclically shuttle a working fluid from the pulmonary artery to the vein and back. The devices may be adjustable to provide desired hemodynamic benefits. Methods are disclosed for making and using the inventive devices.

A sensing device for sensing one or more tissue properties includes an adapter assembly, an actuation assembly, a shuttle, and a piston assembly. The adapter assembly is configured to couple to surgical handheld devices. The actuation assembly extends distally from the adapter assembly and is configured to operably couple to and be engaged by handheld devices coupled thereto. The actuation assembly includes a first drive shaft and a second drive shaft. The shuttle has a clamp and a shuttle sensor, and is coupled to the first drive shaft via a coupling. The shuttle sensor is disposed on the clamp. The piston assembly is coupled to the second drive shaft and configured to compress target tissue between the piston assembly and the clamp of the shuttle.
