A hand held, hand operated apparatus for rotating, or spinning, rotatably oscillating and/or inducing back and forth longitudinal movement in a device, such as an elongated medical device. A drive shaft of the hand held, hand operated rotational drive apparatus includes a ratcheting mechanism capable of enabling oscillating (repeated forward and reverse) rotation of a device that has been coupled thereto when there is little or no resistance on the rotated device, and of enabling an actuator to return to a position that will enable further forward, or driving, rotation of the drive shaft and the rotated device when resistance on the rotated device prevents the rotated device and the drive shaft from rotating in a reverse direction.

Rotational drive apparatus with ratcheting mechanism

An exoskeleton device is capable of being positioned over an expandable instrument, such as a balloon catheter. The exoskeleton device may include an expandable section that receives an expander of the expandable instrument. Expansion of the expander may cause the expandable section of the exoskeleton device to expand and force the expandable section of the exoskeleton device against a surface to be treated. The expandable section may be capable of scoring the surface against which it is forced.

Exoskeleton device with expandable section for scoring

A rooter includes a rotatable element, an actuator for causing the rotatable element to rotate, and a coupling feature for rotatably coupling an elongated medical instrument to the rotatable element. The rotatable element may be at least partially contained within the interior of a housing or another element that remains substantially stationary as the actuator causes the rotatable element to rotate. The rooter may be used with a variety of elongated medical instruments, such as wires, mascerators, needles, drill bits, trocars, catheters, tubes and other elongated instruments that are used to enable or effect medical procedures within the body of a subject. The rooter may be used for a variety of purposes, including, without limitation, the introduction of an elongated medical instrument into the body of a subject or its removal from the subject's body; removing, breaking up, or eliminating obstructions (e.g., blood clots, plaques, etc.) from the body of a subject; and obtaining samples from a subject's body.

Apparatus for rotating medical devices, systems including the apparatus, and associated methods

An elongated medical device includes an elongated tubular element with a series of flexibility enhancing features along a length of the elongated tubular element. Each flexibility enhancing feature may include a circumferential series of cuts. The cuts of one flexibility enhancing feature may be offset relative to the cuts of a longitudinally adjacent flexibility enhancing feature. The flexibility enhancing features may be grouped into two or more interleaved sets, with each set of circumferential cuts being offset relative to the next set of circumferential cuts. Methods for manufacturing such elongated medical devices are also disclosed.

Elongated medical instruments with flexibility enhancing features

An exoskeleton device includes an expandable section. The expandable section may be positioned over an expander, such as a balloon catheter, and expand upon expansion of the expander. The expandable section may include struts that rotate as the expandable section expands. Edges of the struts may score surfaces (e.g., pathology, tissue, etc.) against which the struts are forced as the expandable element expands. The expandable element may carry a medicament, which may be delivered upon expansion of the expandable element.

Expandable exoskeleton devices

A temperature probe for monitoring temperatures of a surface of a tissue or organ within the body of a subject includes a section with a substantially two-dimensional arrangement and a plurality of temperature sensors positioned across an area defined by the substantially two-dimensional arrangement. Such an apparatus may be used in conjunction with procedures in which thermal techniques are used to diagnose a disease state or treat diseased tissue. Specifically, a temperature probe may be used to monitor temperatures across an area of a surface of a tissue or organ located close to the treated tissue to prevent subjection of the monitored tissue or organ to potentially damaging temperatures.

Large surface area temperature sensing device

A cannula-stylet assembly for piercing tissues of a subject's body includes a stylet that is significantly longer than the cannula. The length of the stylet enables introduction of the stylet through the length of both the cannula and a gripping device that has been coupled to a proximal end of the cannula. A medical piercing system may include a cannula-stylet assembly with a long stylet and a gripping device that may remain assembled with the cannula when the stylet is removed from the cannula or a gripping device that remains assembled with a stylet of a conventionally configured cannula-stylet assembly when the stylet is removed from the cannula.

Tissue piercing assemblies

An exoskeleton device is capable of being applied to an outer surface of an elongated medical instrument, such as a catheter or a balloon (e.g., an angioplasty balloon, etc.). The exoskeleton device includes a sleeve or another element that is configured to be placed over a distal portion of the elongated medical instrument, one or more features on the sleeve or other element for performing a procedure within the body of a subject, and one or more elements that communicate with the sleeve or other element and/or the features carried thereby to enable performance of the procedure within the body of the subject. Methods of applying exoskeleton devices to elongated medical instruments and methods of using exoskeleton devices are also disclosed.

Expandable medical device

A tissue resector includes an outer cannula with a cutting element disposed therein. The outer cannula includes an opening that is configured to be associated with a cutting element of the cutting element in such a way that when tissue is drawn into the opening of the cannula, a cutting element of the cutting element can be rotated past the opening to engage and cut into and through the tissue. The outer cannula and the cutting element may also be configured to enable aspiration of the tissue. A tissue resector according to this disclosure may be used with a hand-held, hand-operated rooter.

Tissue resectors with cutting wires, hand operated tissue resecting systems and associated methods

A positioning device is configured to selectively position or otherwise manipulate one or more organs within the body of a subject. The positioning device includes a shaped expandable element that is configured to be selectively transitioned between an unexpanded, or collapsed, state and an expanded state. While in the expanded state, the expandable element repositions or otherwise manipulates an organ. Systems that include positioning devices are also disclosed, as are methods for positioning or otherwise manipulating organs.

Positioning device

A percutaneous access system is disclosed that includes a needle and an inner cannula. The needle includes an internal passageway. At a distal end, the needle includes an expandable section. A distal section of the internal passageway of the needle, which corresponds to the expandable section, is tapered to enable the expandable section to expand and collapse as the inner cannula is positioned within and/or moves through the tapered distal section. The inner cannula may enable grasping and/or aspiration of a sample from a location of interest within a subject's body. Biopsy methods are also disclosed.
