Abstract: A transseptal needle assembly comprised of a cannula, a handle assembly and a stylet is described. The cannula of the needle assembly is of a uniform body construction such that the cannula main portion and needle portion are fluidly connected in one-piece. The handle assembly comprises a handle housing, a handle sleeve and a handle slug. The handle slug provides ballast which improves tactile feel of the needle assembly. In addition, the stylet comprises a stylet housing having a hinged designed that allows for easier control of the stylet.

Abstract: In various examples, an apparatus includes a needle assembly including an outer cannula including a tubular sidewall disposed around a lumen. At least a portion of the sidewall includes an exterior including a polymeric material configured to inhibit skiving of an interior of a dilator with movement of the outer cannula within the dilator. An inner cannula is disposed within the lumen and is selectively slidable with respect to the outer cannula. A handle is disposed at a proximal portion of the needle assembly. The handle includes a first handle portion coupled to and movable with the outer cannula. A second handle portion is coupled to and movable with the inner cannula, wherein the first handle portion is selectively movable with respect to the second handle portion to extend a distal end of the inner cannula from within the lumen of the outer cannula.

Abstract: In various examples, an apparatus includes a gripping member including a body and a gripping portion attached to the body. The body includes a passage configured to accept a needle cannula within the passage. The gripping portion includes an open configuration in which the needle cannula is movable within the passage and a closed configuration in which the gripping portion engages the needle cannula to inhibit movement of the needle cannula within the passage. A coupling member is rotatably attached to the gripping member. The coupling member is configured to selectively couple with a dilator. The coupling member includes a bore fluidly coupled with the passage, the bore being configured to accept the needle cannula within the bore.

Abstract: A novel catheter is described. The catheter comprises a handle, an inner sheath providing an inner sheath lumen extending along a first length from a proximal inner sheath portion supported by the handle to a distal inner sheath portion connected to a cage gripper, and an outer sheath having a second length extending from a proximal outer sheath portion supported by the handle to a distal outer sheath portion connected to a cage housing. The inner sheath rotatably resides inside the outer sheath with the cage gripper rotatably housed inside cage housing. During a surgical procedure, a distal bridge portion of the inner sheath is connected to an opening in the lead sidewall with the lead received inside the cage housing. A gear knob is manipulated to cause the inner sheath to rotate with respect to the outer sheath so that the cage gripper is moved from an un-deployed position housed inside the cage gripper to a deployed position completely surrounding the lead connected to the distal bride.
