An expandable access port includes a port body transitionable between expanded and collapsed configurations. The expandable access port also includes a plug with a first portion secured to the port body and a second portion flexibly coupled to the first portion by an arm. The first portion has an orifice and the second portion has a post insertable into the orifice. A tube is attached to an inflation port on the first portion of the plug. The tube is attachable to a source of inflation fluid and in fluid communication with a chamber of the port body. A lumen extends through the port body and is configured to slidably receive the post or a surgical instrument therethrough. The lumen forms a fluid-tight boundary when the port body is in the expanded configuration.

An apparatus includes a slotted tube having a plurality of first slots and a plurality of second slots; an imager disposed in the slotted tube, the imager having a plurality of corners arranged in the plurality of first slots; and a plurality of light guides disposed in the plurality of second slots.

A dilator system for arterial and venous cannulas, where there is a smooth transition between the dilator and the outer wall of the cannula. One aspect of the subject technology provides a blunt-tip cannula that is used as a dilator for insertion of an arterial or venous cannula. The balloon might either be a single diameter or may have a larger diameter at the distal portion such that the diameter of the distal portion of the balloon dilator matches the diameter of the cannula at the tip. Another aspect of the subject technology is a balloon dilator for cannulae that may be positioned over a guidewire, for guidewire-directed placement of a cannula within a vessel, duct, lumen or heart structure of the body. Another aspect of the subject technology is an inflation system for the balloon dilator, such that the balloon dilator may be deflated and quickly removed from the cannula after the cannula has been positioned and secured within the vessel, duct, lumen or heart structure. Another aspect of the subject technology includes a stiffening element in the balloon dilator along its shaft to increase the rigidity of the combined balloon dilator and cannula to provide improved ease of insertion. Another aspect of the subject technology is an improved curvature of the shape of the right angle dilator that achieves more uniform flow within the dilator and ease of insertion and more even flow within the cannula, and ease of insertion of and retraction of the balloon dilator. Another aspect of the subject technology is a gel-filled balloon dilator that improves ease of insertion of the cannula within the vessel, duct, lumen or heart structure, and can be removed without deflation.

The present invention provides devices and methods for laparoscopic access and wound closure. The device is in the form of a unitary needle device, which enables performance of several tasks, including penetration or puncture of fascia layers, insufflation of a body cavity with gas, and placing a suture for wound closure. In particular, the device features a blunt-tipped stylet having a hook or notch at the proximal end, which can be used to capture a suture.

Various devices, apparatuses, and methods for transseptal puncture and crossing are disclosed herein. A transseptal puncture and crossing device can include novel puncture member having a crossing coil mated to a body portion to be able to both cross a tissue and allow a wire or guard be inserted through the puncture member. Though not required, the puncture member can have one or more of novel features, including a tapered coil portion, a transition cutter, a gripper coil portion, an atraumatic guard, and a shaped cutting wire. Methods for transseptal punctures and crossing include adding rotation, oscillation and/or ultrasound to a transseptal puncture device.

An introduction device for the percutaneous introduction of drainage tubes, in particular thoracic drainage tubes, including: a main body, which has a grip portion adapted to be gripped by a hand of an operator, and a proximal portion provided with an internal longitudinal cavity; a terminal tubular element, which is extended longitudinally and distally from the proximal portion of the main body; a longitudinally extended percussion element, which can slide within the terminal tubular element between a retracted position and an extracted position; and a tubular introducer which forms inside it a through duct and can be configured in a coupled cutting configuration, in which the tubular introducer is fitted on the terminal tubular element, and in an uncoupled configuration, in which the tubular introducer and the terminal tubular element are uncoupled.

In one embodiment, the present disclosure relates to a probe for use in minimally invasive surgery. The probe includes a shaft and a tip extending from the shaft. The tip includes a bulbous shape with a smooth and rounded outer surface. In some embodiments, the shaft is separated from the tip by a neck such that both the shaft and the tip expand outward from a concave surface of the neck. In some embodiments, one or both of a neuromonitoring element and an ultrasound sensor are disposed on the tip. In some embodiments, a probe may include a surface feature that resists expulsion of the probe from a human body when the probe is disposed in the human body. In further embodiments, a probe may include insulated material over a first surface region and conductive material over a second surface region.

The present disclosure relates to the technical field of medical instrument and provides a passage establishment device for posterior spinal fusion minimally invasive surgery. The device includes: a tube, an interior of the tube includes a through hole penetrating through both axial ends of the tube, and a wall of the tube includes an opening portion. The tube of the passage establishment device of the present disclosure can be inserted between the vertebral bodies and can also be removed from between the vertebral bodies. The through hole of the tube forms a surgical passage for the fusion device to penetrate, which can safely protect human tissues and is convenient for doctors to perform follow-up operations. The tube can be installed quickly, and thus the operation time is shortened. It is easy to disassemble, clean, and disinfect the tube.

A puncture instrument kit includes a puncture rod, mesh, and sheath. The puncture rod consists of a puncture head, puncture rod body, and handle. One end of the puncture rod body is connected to the handle and the other end is integrated with the puncture head. The puncture head is arc-shaped with an end gradually tapering to form a tip. The tip of the puncture head is circumferentially designed with a groove for fixing a thread during surgery. The puncture head is smoothly connected with the puncture rod body, and the line between the tip of the puncture head and puncture rod body is at an obtuse angle of 130-140° relative to the puncture rod body. The sheath is sleeved on the puncture rod with the rod tip exposed. The mesh and sheath are designed as separate or integrated, and the tip of the puncture rod is provided with a shape-matching detachable silicone protective sleeve.

An intraosseous access system including an intraosseous driver coupleable with access assembly that includes an obturator assembly having an obturator and an access assembly needle assembly having a needle lumen defining a needle lumen. The access assembly further includes an extension set having an extension tube having extension tube hub and a bag attachment member coupled with the extension tube at opposite ends. The extension tube hub forms a rotating seal with the access assembly. The access assembly and the bag attachment member are contained within separate sterile packages with the extension tube extending therebetween. A fluid pathway extends between the bag attachment member and the needle lumen.
