摘要： A medical sheath includes an elongate member having a sidewall extending longitudinally between a proximal end portion of the elongate member and an opposed distal end portion of the elongate member, and radially between an outer surface of the elongate member and an inner surface of the elongate member. A lumen is defined by the inner surface and extends through the elongate member from the proximal end portion to the distal end portion. At least a first echogenic band is associated with the distal end portion and is secured to the sidewall.

摘要： A medical dilator includes an elongate member having a proximal end portion, an opposed distal end portion, and a lumen extending through the elongate member from the proximal end portion to the distal end portion. A dilating tip is at the distal end portion. The dilating tip has a first end of enlarged cross-sectional area and tapers going in the distal direction to a second end of reduced cross-sectional area. At least a first electrode is associated with the dilating tip. An electrical conductor is electrically connected to the first electrode and extends proximally from the first electrode towards the proximal end portion for electrical connection with an electro anatomical mapping system.

摘要： Devices and methods for providing access to the pericardial cavity while reducing risk of myocardial damage. One method includes using an apparatus to apply pressure to a parietal pericardium, retracting the apparatus, and puncturing the parietal pericardium by delivering electrical energy using a puncture device. Another method includes moving a portion of parietal pericardium away from a surface of myocardium of the heart and puncturing the parietal pericardium by delivering electrical energy using a puncture device. The methods may include a step of confirming that the puncture device is at least partially within the parietal cavity by injecting or aspirating fluid through a lumen in the puncture device or measuring the pressure or electrical impedance at the distal end of the puncture device.

摘要： A system of medical devices includes a needle, an endoscope, and an introducer. The needle extends between a needle proximal portion and a needle distal portion having a puncturing tip. The endoscope extends between an endoscope proximal portion and an endoscope distal portion having a camera. The introducer is for guiding the needle and the endoscope towards a target location. The introducer extends between an introducer proximal portion and an introducer distal portion and has a first lumen extending therethrough from the introducer proximal portion to the introducer distal portion and a second lumen extending therethrough from the introducer proximal portion to the introducer distal portion. The needle is advanceable through the first lumen to position the puncturing tip proud of the introducer distal portion and the endoscope is advanceable through the second lumen to position the camera proximate the introducer distal portion and outside of the lumen.

摘要： Novel and unique medical devices and associated methods are disclosed, for a medical device for puncturing tissue at a tissue site. The medical device is an elongate member having a proximal section, a distal section, and a rail section therebetween. The medical device includes an active tip at a distal end of the distal section and is operable to deliver energy to create a puncture through the tissue. The rail section is configured to both act as a rail for supporting installation of one or more tubular members thereupon, as well as be maneuverable for enabling access to the tissue site.

摘要： A tissue-spreader assembly is configured to be selectively inserted into a patient having a first biological tissue and a second biological tissue, and to be maneuvered proximate to the second biological tissue. The tissue-spreader assembly is also configured to selectively engage, at least in part, an area of the second biological tissue without engaging the first biological tissue. The tissue-spreader assembly is also configured to selectively spread, at least in part, the area of the second biological tissue, and maintain the area of the second biological tissue in a spread-apart condition after the tissue-spreader assembly, in use, selectively engages, at least in part, the area of the second biological tissue.

摘要： An electrosurgical device for puncturing tissue comprises an electrically conductive elongate member which is capable of force transmission from a distal portion of the electrosurgical device to a proximal portion of the electrosurgical device to thereby provide tactile feedback to a user. The proximal portion comprises a handle or hub which includes an electrical connector configured to receive, in a releasable manner, an electrically conductive component operable to be electrically coupled to an energy source.
