Abstract
Provided herein are methods of penetrating tissues using impact-force medical devices. Additional methods as well as related impact-force medical devices, kits, systems and computer readable media are also provided.
Claims37
An impact-force medical device, comprising:
- a body structure that comprises a channel disposed at least partially within the body structure, which channel communicates with first and second ends of the body structure;
- a medical end-effector element directly or indirectly operably connected, or connectable, to at least the first end of the body structure;
- and,
- an asymmetric magnetic element at least partially disposed within the channel, which asymmetric magnetic element is configured to selectively move within the channel at least when a magnetic field, pulse, and/or gradient is applied to the asymmetric magnetic element such that the asymmetric magnetic element reversibly applies an impulse force to the first or the second end of the body structure, which impulse force effects movement of the medical device.

A method of penetrating a tissue of a subject, the method comprising:
- positioning an impact-force medical device in a first position relative to the tissue of the subject using at least a first applied magnetic field, pulse, and/or gradient, wherein the impact-force medical device comprises:
- a body structure that comprises a channel disposed at least partially within the body structure, which channel communicates with first and second ends of the body structure;
- a medical end-effector element directly or indirectly operably connected to at least the first end of the body structure;
- and
- an asymmetric magnetic element movably disposed within the channel;
- and,
- contacting the asymmetric magnetic element with at least the first end of the body structure one or more times with sufficient impact-force using at least a second applied magnetic field, pulse, and/or gradient such that at least the medical end-effector element at least partially penetrates the tissue of the subject.

A system, comprising:
- an impact-force medical device that comprises:
- a body structure that comprises a channel disposed at least partially within the body structure, which channel communicates with first and second ends of the body structure;
- a medical end-effector element directly or indirectly operably connected to at least the first end of the body structure;
- and
- an asymmetric magnetic element movably disposed within the channel;
- a magnetic coil subassembly configured to apply magnetic fields, pulses, and/or gradients at least to the asymmetric magnetic element;
- a controller that comprises, or is capable of accessing, computer readable media comprising non-transitory computer-executable instructions which, when executed by at least one electronic processor, perform at least:
- positioning the impact-force medical device in a first position relative to a tissue of a subject using at least a first magnetic field, pulse, and/or gradient applied by the magnetic coil subassembly;
- and
- contacting the asymmetric magnetic element with at least the first end of the body structure one or more times with sufficient impact-force using at least a second magnetic field, pulse, and/or gradient applied by the magnetic coil subassembly such that at least the medical end-effector element at least partially penetrates the tissue of the subject.
