Abstract: An imaging system for use in a patient is provided. The system includes an imaging probe, a rotation assembly, and a retraction assembly. The imaging probe collects image data from a patient site and includes an elongate shaft with a proximal end and a distal portion, with a lumen extending therebetween. A rotatable optical core is positioned within the elongate shaft lumen and an optical assembly is positioned in the elongate shaft distal portion. The optical assembly directs light to tissue at the patient site and collects reflected light from the tissue. The rotation assembly connects to the imaging probe and rotates the optical assembly. The retraction assembly connects to the imaging probe and retracts the optical assembly and the elongate shaft in unison.

Abstract: Provided herein are imaging systems for a patient including an imaging probe and an imaging assembly. The imaging probe includes: an elongate shaft with a proximal end, a distal portion, and a lumen extending between the proximal end and the distal portion; a rotatable optical core with a proximal end and a distal end, and at least a portion of the rotatable optical core is positioned within the lumen of the elongate shaft; and an optical assembly positioned proximate the distal end of the rotatable optical core, the optical assembly configured to direct light to tissue to be imaged and collect reflected light from the tissue to be imaged. The imaging assembly is constructed and arranged to optically couple to the imaging probe. The imaging assembly is configured to emit light into the imaging probe and receive the reflected light collected by the optical assembly.

Abstract: A trocar or surgical port assembly includes an annular body attachable to a patient at an incision in a patient. The annular body includes a cylindrical insert portion defining a proximal end and a distal end and a flange disposed at the proximal end of the cylindrical insert portion. A skirt is attached to the distal end of the cylindrical insert portion and extends distally from the annular body and includes a flexible web and a wire attached to the flexible web that in a multiple looped configuration of non-intersecting curved portions positioned in the vicinity of the distal portion of the skirt to enable the flexible web to be biased via a biasing force exerted by the wire into a funnel-shaped open configuration having an opening of the skirt at the distal portion of the skirt that is larger than an opening of the skirt at the proximal portion.

Abstract: A surgical port comprising a body and first and second cannula extending from the body and movable with respect to the body via an instrument inserted through the respective cannula. The cannulas can extend distally from the body and can include one or more seals. A port assembly and first and second instruments manipulatable in a crossed configuration are also disclosed.

Abstract: Various embodiments of a laparoscopic trocar assembly are disclosed. The port assemblies include inserted parts that protect the patient's tissues at the point of deployment. The port assemblies include seals for maintaining pneumoperitoneum both when instrument are being used and when instruments are not inserted.

Abstract: A collection device and a method for collecting a biological sample, particularly whole blood, includes a separating member to separate the whole blood into its components, and at least reagent positioned to selectively interact with a component of the separated sample. The reagent is able to selectively interact with the plasma/serum, and is prevented from contacting or interacting with the whole blood.

Abstract: A surgical portal assembly includes a portal member defining a longitudinal axis and having a longitudinal passageway for passage of a surgical object, and being dimensioned to pass through tissue to provide access via the longitudinal passageway to an underlying operative site and a plurality of object seals in mechanical cooperation with the portal member and positioned to intersect the longitudinal passageway. Each object seal has inner surfaces defining a seal passage to permit passage of the surgical object. The inner seal surfaces of each object seal include a primary finger segment and secondary finger segments on opposed sides of, and in spaced relation to, the primary finger segments.

Abstract: The medical puncturing device includes an actuator, a shield, and a skin puncturing assembly. The actuator and shield are movable relative to one another. The skin-puncturing assembly includes a carrier and a skin-puncturing element. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the distal end of the skin-puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin-puncturing element is exposed to puncture the skin of a patient. The carrier is maintained in the retracted position by interference engagement between the carrier and shield. A drive spring is provided to move the carrier from the retracted to puncturing positions. A retraction spring is provided to return the carrier to a position wherein the shield encompasses the skin puncturing element.
