The present disclosure illustrates an introducer sheath with a partially annealed metal frame. The introducer sheaths described herein include a hub coupled to a shaft. The shaft comprises a braided wire frame with (i) an annealed distal portion that prevents the braided wire frame from unraveling at a distal end, and (ii) a second portion that is unannealed; a jacket encompassing the braided wire frame; and a liner forming an inner wall.

A vascular introducer sheath device comprising a tubular main shaft and a main hub attached to the proximal end of the main shaft. Attached to the proximal end of the main hub is a header hub, which has a first arm and a second arm. The header hub is attached to the main hub in a releasably locked configuration. As such, the header hub is functionally detachable from the main hub. The header hub and the main hub could together have a twist-on or snap-on mating mechanism. An example of such a mating mechanism is a male lock fitting on the header hub and a female lock fitting on the main hub. Further, there could be a side port on the main hub and a side port on the header hub, wherein the side ports for the main hub and header hub are oriented on a same plane when the header hub and the main hub are in locked configuration.

A surgical access device includes a check valve having baffling discs, a tube, and a housing. The housing has first and second housing halves. Baffling discs are configured to form a lumen. Each baffling disc is a conical annulus and is stacked adjacent to another baffling disc and spaced apart via spacers disposed on each baffling disc. The spacers help define a first gap between adjacent baffling discs for defining a first fluid path. A cover is coupled to the housing and permits access to the surgical access device. The housing is configured to receive the tube and the baffling discs, and the baffling discs are spaced apart from the first and second housing halves defining a second gap therebetween for defining a second fluid path. The first and second gaps form fluid convection channels for guiding fluid flowing in a proximal direction back into itself.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to adapting medical devices for use of a distal portion of a medical device within a restricted anatomical area. In one example, a coupling device may comprise first and second ends. A first end may be configured to couple to a locking member of a medical device delivery system. The first end may comprise a lumen extending therethrough. The second end may comprise a lumen continuous with the lumen of the first end. The second end may be configured to couple to a channel opening of an endoscope. Other embodiments are contemplated.

This present disclosure provides devices, systems, and methods relating to the management of a subject's medical needs involving safely accessing a body cavity. In particular, the present disclosure is directed to body cavity conduit devices and systems that facilitate repeated access to a subject's body cavity for removing fluid or performing a procedure in a manner that provides enhanced comfort, safety, and efficacy.

In a sheath device for inserting a catheter into a patient's body, comprising a first sheath having a proximal end and a distal end, wherein when used as intended the distal end of the first sheath is provided for arrangement in the patient's body and the proximal end of the first sheath is provided for arrangement outside the patient's body, and wherein the first sheath comprises a tubular section and a sheath housing, which is disposed at the proximal end of the section and comprises a receiving channel for a catheter, according to the invention the tubular section is detachably held in a clamping element of the sheath housing in a non-positive manner so as to be able to easily shorten the tubular section.

A hydraulically driven surgical apparatus may be a tube enclosing a first channel filled with a first fluid. Changing a fluid pressure in the first channel may trigger a deformation of the tube. The deformation of the tube may perform an action associated with a surgical procedure. Related methods for steering a hydraulically driven surgical apparatus are also provided.

The present disclosure relates to a subcutaneous fixation system for fixing medical devices, in particular catheters, and keeping them in position with respect to an access point on the skin of a patient.

A percutaneous access device for use in minimally invasive surgery includes an elongated body having a proximal portion and an opposing distal portion. The proximal portion has a proximal bore extending therethrough and the distal portion has a distal bore extending therethrough. The distal portion of the body is hingedly connected to the proximal portion in a first percutaneous access position and a second anchoring position. In the first percutaneous access position the distal and proximal bores are linearly aligned when a surgical instrument is inserted into both the proximal and distal bores. In the second anchoring position the distal bore is angularly displaced from the proximal bore when the surgical instrument is removed from the distal bore.

In a sheath device for inserting a catheter into a patient's body, comprising a first sheath having a proximal end and a distal end, wherein when used as intended the distal end of the first sheath is provided for arrangement in the patient's body and the proximal end of the first sheath is provided for arrangement outside the patient's body, and wherein the first sheath comprises a tubular section and a sheath housing, which is disposed at the proximal end of the section and comprises a receiving channel for a catheter, according to the invention the tubular section is detachably held in a clamping element of the sheath housing in a non-positive manner so as to be able to easily shorten the tubular section.
