The disclosure provides various embodiments of systems to facilitate the cutting of luminal tissue structures percutaneously.

A medical system may include an insertion device including a delivery shaft with at least one lumen, a tube coupled to an exterior of the delivery shaft, and an adaptor coupling a distal end of the delivery shaft to a distal end of the tube. One of the delivery shaft and the tube may be configured to receive an energy delivery device, and the other of the delivery shaft and the tube may be configured to be coupled to a suction source to apply suction.

A surgical access device sterilizes tissue at a surgical site and/or the air at the surgical site. The surgical access device may include a cannula including an elongated shaft having a fluid delivery channel defined therein, a fluid delivery port coupled to the cannula and in fluid communication with the fluid delivery channel, and a porous sleeve disposed around the elongated shaft and in fluid communication with the fluid delivery channel. The fluid delivery channel provides a pathway for fluid flow (e.g., an anti-infective agent) from the fluid delivery port into the porous sleeve. The surgical access device may include a cannula including an elongated shaft having an anti-infective agent disposed therein. The surgical access device may include an instrument housing secured to a cannula, and a light source (e.g., an air sanitizing light source) disposed within a cavity of the instrument housing.

Present invention relates to a medical device for blood vessels compression that is applied to a limb of a patient in order to achieve local haemostasis. The compression device of the invention is equipped with a compression control mechanism distal to the compression area, which controls the compression of the device onto the patient's limb by adjusting the tension of the strap used for attaching the device to the patient's limb. The device further comprises a stabilising support, which prevents the device from changing its position, when it is applied to the patient's limb.

Tissue ligation devices and methods are provides to mechanically strangulate abnormal or undesirable tissue. Tissue ligation devices include a catheter having an outer diameter smaller than the inner diameter of a standard endoscope channel such that the catheter can be inserted into the endoscope. Tissue ligation devices also include a ligation system with an expandable hood disposed located at the distal end of the catheter. A suture extends through a lumen of the catheter and has a distal loop portion exposed outside of the expandable hood.

A surgical access system comprises a trocar, an insufflating optical obturator slidably insertable into the trocar, and a laparoscope slidably insertable into the obturator. A distal end of the obturator comprises a tip, at least a portion of which comprises a wall with a generally uniform thickness comprising a transparent material. At least one vent hole disposed at the obturator tip is fluidly connected to a gas flow channel defined by an interior surface of the obturator and the laparoscope, which is fluidly connected to an insufflation gas inlet disposed at a proximal end of the trocar. Improved optical characteristics of the trocar system permit precise and accurate visual placement thereof into a body cavity. Accordingly the access system is suitable as a first entry surgical access system. Embodiments of the trocar access are also useful for drug delivery, and/or for fluid and/or tissue aspiration.

A gripping and positioning tool for a poly-axial screw insertion guide comprises a handle, a main body connected to the handle positioned at a first end of the main body and a coupling zone positioned at a second end of the main body. The coupling zone is able to vary its position with respect to the insertion guide keeping the application direction of the force applied by the surgeon to said instrument constant.

A balloon assembly (200) that can be attached to a band assembly (300) to form a hemostasis band (100) used to perform hemostasis on a puncture site (89) of a human being (90). The balloon assembly (200) can include a balloon (210) that provides for being inflated to apply pressure to the puncture site (89), one or more openings (220) that provides for the insertion of the band assembly (300), and an inlet (230) for inflating the balloon (210).

A tissue displacement/separation device includes a seamless bladder constructed of a biodegradable polymer. The bladder is expandable from a collapsed or rolled state for insertion into a body between a first and second tissue to an expanded state for separating the first and second tissue.

The present disclosure relates to a surgical drape to be used in conjunction with a surgical procedure, and more specifically to a surgical drape that includes one or more of the following: (1) a patient drape for use with a standalone non-draped image acquisition device; (2) a patient drape for use with a standalone non-draped image acquisition device with image guidance navigation technology; (3) the means to provide temporary sterile coverage of an underlying sterile field; (4) the means to provide sterile separation of at least a portion, if not the entire temporary sterile coverage; and (5) the means to provide covering of the undersurface of the operating surface and enclosing any suspended medical devices, wires, cables, tubes, etc.
